Serial Lite IV - Rx Simulation Issues
Hello, I'm having trouble with the RX in side when simulating the F-Tile Serial Lite IV example design. Enviroment: - Quartus Prime Pro Edition 26.1, Windows - Questa Altera FPGA Edition-64 2025.3, installed with Quartus 26.1, with its precompiled device libraries - Device AGMF039R47A1E1VC (Agilex 7 M-Series) - F-Tile Serial Lite IV IP: FGT, NRZ, 8 lanes, 18.0048 Gbps, RS-FEC enabled, FULL streaming mode, PMA reference clock 180.048 MHz, System PLL 562.65 MHz - Example design generated from the IP parameter editor (Generate Example Design). Problem 1 : the generated run_mentor.tcl cannot compile the device libraries. run_mentor.tcl sets QUARTUS_SIM_LIB_DIR to $QUARTUS_ROOTDIR/eda/sim_lib2, DEVICES_SIM_LIB_DIR to $QUARTUS_ROOTDIR/../devices/sim_lib2 and ENABLE_QE_LIBRARY_COMPILATION to true. Both folders exist, but dev_com fails with vlog-7 (Failed to open design unit file) on the first file of every device library : quartus/eda/sim_lib2 : 220model.v, sgate.v, altera_primitives.v, altera_mf.v, altera_lnsim.sv, tennm_atoms.sv, tennm_hssi_atoms.sv, ctfb_hssi_atoms.sv, ctr_hssi_atoms.sv devices/sim_lib2 : tennm_fm_hps.sv, tennm_fp8_noc.sv, tennm_revb_io96.sv, tennm_revb_io96_iopll.sv ,ctfb_hssi_atoms_ncrypt.sv and ctfb_hssi_atoms2_ncrypt.sv, which the script also compiles, are not present anywhere in the installation. The only ctfb_hssi_atoms file installed is questa_fe/intel/verilog/src/ctfb_hssi_atoms.sv. Problem 2 : with the precompiled libraries the rx never comes up To get past problem 1, the two sim_lib2 lines were removed from run_mentor.tcl and ENABLE_QE_LIBRARY_COMPILATION was set to false, so the design binds to the precompiled Questa Altera FPGA Edition libraries. The macros in USER_DEFINED_VERILOG_COMPILE_OPTIONS were left as generated. Compilation and elaboration then succeed, and : - Phy TX Lanes Stable and Phy EHIP ready assert at 58,215 ns, TX link_up at 58,223 ns. - rx_pcs_fec_phy_reset_n is released at about 200 ns together with the TX, and rx_reset_ack asserts during the reset and clears after the release. - rx_cdr_lock stays 0 on all 8 lanes and rx_link_up never asserts : the testbench stays at "Waiting for RX Link Up". The run was stopped at 126.5 us, 68 us after TX link up. The reference logs in UG-20325 show RX link up 20 to 28 us after TX link up. - The F-tile model reports a single lane state change per lane, "State change from S0, R0, W0 TO S2, R0, W0", finished at 3,625 ns, and nothing after that. - The simulation runs at about 5 hours of wall-clock time for 126.5 us. Our own design, which uses the same IP, behaves identically on this installation. Questions 1. Where should the files that run_mentor.tcl expects in quartus/eda/sim_lib2 and devices/sim_lib2 come from ? Is an installation component missing ? 2. Is the example design supported with the precompiled Questa Altera FPGA Edition libraries ? If so, what does the FGT RX need to reach rx_cdr_lock ? 3. Is this a known issue in 26.1, and is there a patch or a workaround ?Solved182Views0likes9CommentsInquiry About Package Internal Trace Lengths of Arria 10 PCIe Pins
I referred to the following document to check the package internal trace lengths of the pins on the Arria 10 FPGA. Device: 10AX032E3F29E2LG Reference document: 10AX032EF29_netlength.xlsx However, I could not find the internal trace length information for the transceiver pins in this document. Examples of the pins of interest include: REFCLK_GXBL GXBL1D_TX/RX Could you please let me know if there is any documentation available that provides the package internal trace lengths for these transceiver pins? If such documentation is not publicly available, could you recommend any reference materials or design guidelines that would be useful for PCB routing of these transceiver pins, particularly for considering package delay and trace length?20Views0likes2CommentsHyperRAM Hyperbus options for Agilex
In migrating a Xilinx design : We are looking to use a A5E A 007 B23B device with a NIOS-V or other RISCV soft core. Because we need to use the HSIO pins for ~ 20 pairs of LVDS, and the entireHSIO bank (96 wide) having to be at 1.3V to support LVDS mean that we cannot use the internal LPDDR4 memory controller. Please confirm my understanding - that although the 96 wide I/O bank can be split into two functional sub banks (2A, 2B etc) (to support say, LPDDR4(16 bit), and something else , that we CANNOT split the VCCIO-BANK between the two sub banks ? (to have 1.1V for LPDDR4 and 1.3V for LVDS) The projects do not need much memory- a 64 Mbit HyperRAM device hanging from 1.8V HVIO would do the job (perhaps max clock 125 MHz on HVIO ?) What instantiable cores do ALtera have in the war chest for HyperRAM? There is a 3rd party Hyperbus controller IP but we wont want to spend $10,000 on it, as moving from a cheaper Xilinx device to a less competitive Altera device is already a big job and we do not think it deserves having that much more money spent on it. (Efinix have a free Hyperbus core, Xilinx have a free Hyperbus core....) Regards Glen.Solved170Views0likes6Commentsneed for Agilex 5 utilization&performance support in Altera IP ?
Altera, please update the documentation - missing Agilex 5 IP support. Overall question- is it expected that users do all their work in DSP builder to generate performance and utilization, IE use DSP builder as a wrapper for all Altera DSP IP ? Example https://docs.altera.com/r/docs/683208/24.1/fir-ii-ip-user-guide/fir-ii-ip-core-performance-and-resource-utilization no numbers for Agilex 5, and preliminary support https://docs.altera.com/r/docs/683366/24.1/unified-fft-ips-user-guide/unified-fft-intel-fpga-ips-device-family-support support but no utilizatiion or performance numbers is it expected that users run {2.2. Generating a Unified FFT IP} generate the HDL in QUartus to get utilization ? But surely the fmax and utilizatiion will not be final until the synthesis and P&R tools have done their jobs ? https://docs.altera.com/r/docs/683374/17.1/fft-ip-core-user-guide/dsp-ip-core-device-family-support no support for Agilex 5 (old core?) regards, glen5Views0likes1CommentWhat are the issues in Nios® V processor for designs targeting Agilex® 27 FPGA device?
Description Due to a problem in the Quartus ® Prime Pro Edition software version 26.3, Nios® V Debug IP fails to execute dmcontrol.hartreset on a halted Nios® V processor. This is because there is a bug in Nios® V/c processor, when servicing dmcontrol.hartreset request while halted. If the processor is a running state, dmcontrol.hartreset can be executed successfully. Resolution To work around this problem in the Quartus ® Prime Pro Edition software version 26.3 (select one), Use dmcontrol.ndmreset to reset the processor at any states. Use dmcontrol.hartreset only when the processor is at running state. This problem is currently scheduled to be resolved in a future release of the Quartus ® Prime Pro Edition Software.Questa Prime Pro 25.3 license rehosting
Hello, I need to get a license rehosting for our Questa Prime Pro license as it is a fixed license to a machine that will no longer be in use at our company. I worked with Intel Customer Support last year on generating the license and was told they could do the rehost for us if we need it in the future but since everything has migrated to Altera including the license generation, could someone please help. Thanks.38Views0likes3CommentsHaven't received the license file for Questa-FPGA Starter Edition after registration

Agilex 5 parts have high static power by industry traditions, so using Agilex in our designs needs some attention. Using the PTA 26.1.110: fixed junction temperature Is there going to be facility in the PTA to vary the core power supply values over the min and max range ? via tcl ? Will there be a model update soon? most of the values I get seem same for ES and production silicon in the PTA. (static power , 50 deg C, typical ) power of 100 DSPs at 200 MHz, + LPDDR4(32 + usage defaults) A5EE008BB23BE6X : 551mW , + 200mW, +576 mW A5EE008BB23BE6S : 759mW, +200mW , +576mW A5EE008BB23BE5S : 666mW, +216 mW, +592mW A5EE008BB23BE4S : 739mW , +227mW, +604mW sweet spot speed/static/cost appears to be -5 notes : Static power is 2x Xilinx ZU2CG.... Turning on all those I/Os for the EMIF LPDDR4 hurts alot for Agilex5. ALthough the defaults for EMIF write/read and toggle rates are high (50%) so, might be pessimistic. But, the DSPs consume about half what XIlinx Ultrascale+ does.... FWIW Xilinx Ultrascale+ DSP consumption is 560mW (25x18) for same task. So Agilex wins there . (but Ultrascale+ can operate much faster -1 xilinx (slowest) = -2V Agilex (fast)) . Agilex 5 static and I/O power is massively higher, but when it gets busy, Agilex 5 fabric functions are lower power cost than Ultrascale+. Agilex5 may not be the best choice for battery operated devices... Agilex 5 is best when it is busy and heavily utilized, only then it has power advantages over Ultrascale+ Glen44Views0likes3Comments

PACKET CLASSIFICATION | FPGA | NETWORKING + SECURITY Every packet decision starts with classification. Routers, firewalls, SmartNICs, security gateways, and service-edge platforms must determine which policy applies before traffic can be forwarded, blocked, inspected, redirected, or prioritized. TCAM earned its place in these systems because it provides predictable lookup behavior and native ternary matching for ACL and LPM workloads. But as policy databases grow, search keys widen, and rules change more frequently, the traditional approach of scaling specialized ternary memory creates tougher tradeoffs in capacity, power, resource utilization, and system integration. Altera Stellar solutions takes a different approach. Instead of scaling packet classification by building ever-larger ternary-memory structures, Stellar turns classification into an optimized search problem that runs on configurable FPGA resources. The result is an FPGA-native path for large, dynamic packet-classification tables without giving up the policy semantics that made TCAM useful in the first place. TCAM scales through memory expansion. Stellar scales through search intelligence. Keep the TCAM semantics. Change the scaling model. Stellar preserves the intent of ACL, LPM, and multi-field classification, but changes how those rules are represented and searched. The Stellar Software Stack organizes policies into optimized graph structures, partitions the rule database, and continuously manages those search structures as the database evolves. The hardware then executes the search using configurable FPGA search engines while rule information is stored in conventional memory resources. Depending on the configuration, Stellar can use on-chip M20K memory, eSRAM, DDR, or HBM. That gives architects more freedom to balance throughput, capacity, latency, power, and FPGA resource use around the needs of the actual system. Use dense memory where it makes sense, and intelligence where it matters A traditional TCAM combines storage and comparison circuitry inside specialized ternary-memory arrays. That architecture delivers deterministic matching, but scaling the table means scaling the specialized comparison structure as well. Stellar separates rule storage from search execution. Ternary information can be represented as value-and-mask data in conventional memory, while graph organization and software-managed optimization direct each search toward the relevant parts of the database. As tables grow from thousands of entries toward hundreds of thousands or millions, this creates a different path for scaling capacity and power. The white paper goes deeper into why this matters, including the tradeoffs between TCAM and Stellar, the role of memory hierarchy, and a set of Stellar configurations spanning different key widths, capacities, memory resources, and projected five-tuple performance. Bring classification into the programmable datapath The value is bigger than the lookup engine itself. Stellar is designed to operate inside the FPGA alongside packet parsing, telemetry, encryption, traffic management, host-interface logic, and customer packet-processing RTL. For system architects, that means classification can become part of the same programmable platform already handling the datapath. A firewall can pair large, dynamic ACL processing with the rest of its traffic pipeline. A router can combine LPM and policy enforcement with programmable networking functions. A SmartNIC can integrate flow classification with offload and customer-specific acceleration. That system-level flexibility is especially relevant for 100GE to 400GE designs where classification must scale without consuming the platform that surrounds it. Read the full whitepaper! The full Altera white paper, Altera TCAM Alternative Solutions Scale Packet Classification to Millions of Rules for Networking Equipment, explains the architecture behind Stellar and the design choices that make it different. It covers TCAM fundamentals and scaling limits, Stellar graph-based search and software partitioning, memory-hierarchy options, configuration examples, quantitative architectural comparisons, dynamic updates, and deployment use cases across networking and security. Read the white paper See how Stellar uses search intelligence, configurable FPGA resources, and a flexible memory hierarchy to create a scalable alternative for large ACL and LPM workloads.

September 28, 2026 The next generation of embedded systems will not be defined by compute alone. It will depend on how quickly, reliably, and intelligently systems can move data from the physical world into AI engines and turn insights back into action. That message came through clearly at Embedded World North America 2026, held September 22–24 at the Anaheim Convention Center. For Altera, the show provided an opportunity to highlight a growing collaboration with NVIDIA and demonstrate the role of FPGAs in high-performance edge AI architectures. Connecting sensors to AI with flexibility and determinism At the center of the story was NVIDIA Holoscan Sensor Bridge technology. The solution creates a high-bandwidth, low-latency path between real-world sensors and GPU-based AI processing, an increasingly important capability for robotics, industrial automation, intelligent video, medical systems, and other physical AI applications. FPGAs are well suited to this role because they can provide deterministic processing, flexible I/O, and protocol adaptation close to the sensor. Rather than forcing every application into the same hardware configuration, FPGA-based designs can be tailored to performance, connectivity, and latency requirements of a specific system. In the show’s keynote, NVIDIA Vice President Deepu Talla described the value of this flexibility: “You can select any of the Altera FPGAs depending on the application and pair them with any of the NVIDIA frameworks.” Altera’s post noted that Altera offers Holoscan Sensor Bridge solutions spanning 10G to 100G, where 25G and 100G offer significantly more bandwidth compared to other Holoscan ecosystem partners, helping developers scale connectivity for demanding edge workloads. The result is a practical sensor-to-compute architecture: Altera FPGAs handle the flexible, deterministic front end, while NVIDIA platforms provide the accelerated environment for AI and robotics workloads. An ecosystem approach to accelerating development The demonstrations also underscored that successful edge AI deployments require more than individual components. Developers need reference designs, production-ready boards, and partners that help bridge the gap between evaluation and deployment. Altera’s growing Holoscan ecosystem includes more than 10 reference designs and partner boards. These building blocks can help teams reduce integration effort and move faster from proof of concept to a real-time AI product. One example was on display at Altera partner Critical Link’s booth. Critical Link was recognized as a Best in Show Award winner in the AI & Machine Learning category at the show. Visitors to the booth could see a live demonstration of a 5-camera Holoscan Sensor Bridge solution, using Critical Link’s MitySOM-A5E as the featured Agilex® 5 FPGA hardware platform. The demonstration showed how an Agilex 5 FPGA-based system can help bring sensor data into an NVIDIA-powered AI pipeline while preserving the low-latency, high-bandwidth behavior required by edge applications. From 10G to 100G: Building the data plane for edge AI Altera’s Holoscan Sensor Bridge solutions are designed to make the sensor-to-GPU path faster and more adaptable. A recent Altera technical blog describes 10G, 25G, and 100G reference designs, including a 25G design on Agilex 5 SoC FPGAs for multi-camera sensor data flow and accelerated processing at the edge. In this architecture, the FPGA serves as the data plane: connecting to diverse sensors, aggregating streams, adapting protocols, and preprocessing data before it reaches the NVIDIA GPU. That division of labor helps reduce data-movement bottlenecks while preserving deterministic timing and giving developers room to evolve the system as sensor interfaces and AI workloads change. Altera Technical Holoscan blog for Robotics: Altera Pushes the Boundaries of Edge AI with New Holoscan Sensor Bridge Solutions | Altera Community - 355665 Watch the 25G Holoscan demo video: YouTube/Altera Why the sensor-to-compute path matters As AI moves into physical environments, system designers are balancing several competing requirements: Real-time response: Applications such as robotics and industrial inspection cannot always afford the delay of sending raw sensor data to a remote system. High-bandwidth data movement: Modern sensors generate increasingly rich data streams that must be transported without creating a bottleneck. Deterministic behavior: Safety-critical and industrial systems need predictable timing and consistent performance. Design flexibility: Product teams must support different sensors, interfaces, and deployment conditions without redesigning the entire platform. Faster development: Reference designs and ecosystem partnerships can shorten the path from concept to production. The Altera and NVIDIA approach addresses these needs by combining FPGA-based connectivity and processing with GPU-accelerated AI. It gives developers a modular foundation for building systems that can adapt as sensors, models, and application requirements evolve. Building what comes next at the edge The conversation at Embedded World North America 2026 pointed toward a broader shift in embedded design. Edge systems are becoming intelligent, connected, and increasingly autonomous, but their performance still depends on the data path that feeds them. By pairing Altera FPGAs with NVIDIA platforms and collaborating with partners such as Critical Link, developers gain more options for designing that path. The combination of flexible hardware, high-speed connectivity, and accelerated AI can help transform raw sensor input into timely decisions at the point where data is created. For teams developing the next generation of robotics, industrial automation, intelligent vision, and physical AI systems, this is the opportunity: Build a sensor-to-compute architecture that is fast enough for today’s workloads, flexible enough for tomorrow’s requirements, and ready to scale from demonstration to deployment.

As AI, cloud, and high-performance computing systems continue to scale, data center operators need more bandwidth within increasingly constrained power and thermal envelopes. Linear Pluggable Optics (LPO) offers an important path forward by simplifying optical modules, reducing power consumption, and lowering latency. LPO places signal-conditioning responsibilities in the host device, allowing the optical module to operate without the DSP used in traditional retimed optics. This architecture can reduce optical module power by 30% to 40%, helping data center designers increase connectivity density while simplifying cooling and thermal management. Altera Brings LPO to the FPGA Market Altera is the first FPGA provider to publicly demonstrate Linear Pluggable Optics interoperability using production FPGA devices. Continued validation with LPO modules from Amphenol and FS further demonstrates the breadth of the emerging ecosystem supported by Altera. Agilex® 7 FPGAs and SoCs bring the power and latency advantages of LPO to programmable platforms used in SmartNICs, data processing units, AI accelerators, and custom infrastructure. The initial public demonstration established that Agilex 7 devices could successfully interoperate with 400G LPO modules. The latest validation advances that milestone by confirming that the implementation meets the performance requirements expected for deployment in demanding data center environments. Validated for Real Deployment Conditions Comprehensive testing confirms that Agilex 7 F-Tile transceivers meet the electrical and link-performance requirements defined by the 100G-DR-LPO specification. The validation demonstrated: Compliance with the required transmit, receive, and link-performance criteria Successful interoperability with LPO modules from Amphenol and FS Successful LPO connectivity across distances from 1 meter to 500 meters Consistent performance across temperature and voltage conditions Measurable performance margin beyond required thresholds Testing covered demanding signal conditions, voltage variation, and temperatures ranging from minus 40 degrees Celsius to 105 degrees Celsius for electrical characterization. Functional link testing included a 1-meter LPO connection, a 100-meter active optical cable, and 500-meter LPO modules from Amphenol and FS. The results demonstrate robust, repeatable operation across multiple module suppliers and link distances, with measurable margin relative to the required performance limits. For customers, this validation provides confidence that Agilex® 7 support for LPO is ready for real-world deployment. Following the industry’s first public FPGA interoperability demonstration, the solution has now been evaluated against LPO performance requirements using modules from multiple suppliers and over link distances up to 500 meters. Together, these results demonstrate a practical foundation for deploying LPO connectivity in next-generation data center systems. More Efficient Connectivity for AI and Cloud Infrastructure The value of LPO grows as data centers deploy more high-speed optical connections. Eliminating the DSP from each optical module can reduce power across thousands of links, simplify optical module design, ease thermal pressure at the front panel, and support lower-latency data movement. Agilex 7 FPGAs add programmability to this more efficient optical architecture. Customers can combine LPO connectivity with packet processing, acceleration, security, telemetry, and evolving protocol support on a single adaptable platform. This flexibility is especially valuable for AI clusters and cloud infrastructure, where workloads, network architectures, and connectivity standards continue to evolve. Validation with multiple module vendors also gives system designers greater flexibility as the LPO supplier ecosystem continues to develop. Ready for the Next Generation of Data Centers The combination of public interoperability and comprehensive validation marks a major step for LPO in the FPGA market. Altera has demonstrated that LPO works with production Agilex 7 devices and validated that the solution meets key LPO requirements with measurable operating margin. This gives customers a proven foundation for evaluating and deploying lower-power, lower-latency optical connectivity in real data center environments. With Agilex® 7 FPGAs, LPO is ready for real-world data center deployment.
