Cyclone V SoC 5CSXC6 Series GXB Utilization and Limitations
Dear Intel Altera, I would like to confirm that the 6 channels GXB device: Q1) Do it possible to use all 6 TX / RX GXB Transceivers when Hard PCIe is used. Based on: CV-53004 There are no specific diagram to explains the single PCIe hard core device with only 6 channel case. Q2) Based on the document: CMU PLL will use CH5 and do this simply means there will be one extra for PCIe Hard-Core? Q3) If not understood falsely, Either PCIe X2 GEN1 + 4 custom GXB usage nor PCIe X4 GEN1 + 2 custom GXB usage is possible? And most protocol uses 1,2,4 and the only possible case is PCIe X4 GEN1 + 1 custom GXB? A little more info from CV-53002 So in order for PCIe Hard Core to run x2 or x4 CH4 must be used. As a result for custom TRX there is no way to use CH1 when PCIe is > x1? Thanks, BrianAltera SSLC License

Why does my Altera FIR IP, configured for interpolation by 80, produce the expected outputs when I provide 3 input samples, but fail to produce the expected behavior when I provide 10 input samples? In this case, the FIR IP keeps tready asserted high, but only generates 4 valid outputs. What could be causing this behavior? I am simulating this in Quartus Prime Lite Edition.241Views0likes7CommentsQuartus and power domain
We actually one remaining pending issue with the Agilex chip that we can't get resolved and might need some help. The basic description is that when comparing the power consumption of the Agilex 5 on our module, to the Agilex 5 on the dev kit, at same temperature, before any configuration, our Agilex 5 consumes about 0.5-1W more. Besides this, all sub-systems seem to operate correctly (CPU, memory, FPGA, I/Os). This additional power consumption is worrying though, and we would like to understand it before spinning the next revision. Regarding the excess power on our board, it might also be a design issue, but we didn't find any hint yet despite multiple deep reviews and investigations. We already spent several weeks looking at this in every way we could think about, so there is already quite a bit of things we tried out, such as: - Measured the power rails, from the outside and from the inside as well, checking if there is any unexpected difference - Measured temperature from the outside (thermal camera) as well as from the multiple internal sensors - Reviewed power sequence, playing with various combinations to see if it made any difference - Reviewed multiple times schematics against documentation and dev kits The extra power is on the core rail. Now please look at the attachement: We collected side observations on an non-configured FPGA. Our board has a temperature-dependent power consumption. So we simply switched the fan off for a short period and then switched it back on. The main power consumption is on the 0.8 V rail (U500 RAA210130). A second interesting observation is the internal temperature of the Agilex: L0_0 is significantly hotter than the other three. When the fan is switched back on, the power consumption returns to its initial value. Very strange and unusual behavior. Could this somehow help set priorities and allow us to rank the most/least likely directions for investigating the source of the elevated power consumption?73Views0likes3CommentsLisence issue when running .do script
Hello, I am a beginner using the Questa FPGA starter edition for practicing SystemVerilog coding. I downloaded the 2025.2 Version and obtained the fix lisence according to NIC ID (my PC's Ethernet adapter's MAC address). And I set accordingly the environment variable(LM_LICENSE_FILE and SALT_LICENSE_SERVER) pointing to the .dat file. The software Questa run successfully. But when I want to use a .do script to run a simple SV simulation, the process failed and showed as attachment 1. The programm is simple and I believe it has no advanced grammar (attachment 2 and 3), but it still failed. Is that the limination of Starter Edition or problem about lisencing? Thank you in advance.143Views0likes7CommentsNeed Step-by-Step Guide: Configuring Arria 10 HPS for UART0 Access (Tools & Workflow)
Hello Altera Community, I am starting a new project using the Intel/Altera Arria 10 SoC FPGA. My immediate goal is to successfully configure the Hard Processor System (HPS) side of the chip and enable HPS UART0 access so I can view the boot messages and interact via a serial console terminal. Since I am new to the Arria 10 HPS ecosystem, could someone provide a detailed, step-by-step workflow of the procedure? Specifically, I would appreciate guidance on: 1.

I am hoping to create a script which will automatically package the IP I am working on as a packaged subsystem. So far, I have automated the creation of an IP directory which describes a new component using a _hw.tcl file and the various source files. I believe the next step is to take this component, instantiate it in a Platform Designer system, and create a Packaged Subsystem using it. I am also hoping that I can parameterise and hide/modify ports of the packaged subsystem, like I can with the _hw.tcl component description. I am encountering a problem; I am running the following command: qsys-script --script=create_packaged_subsystem.tcl --new-quartus-project=my_project_name However, the script fails for the following reason: Error: invalid command name "set_package_property" Here is the script itself (more or less a copy-and-paste from the GUI): package require -exact qsys 26.1 set_package_property NAME "packagename" set_package_property DISPLAY_NAME "PackageName" set_package_property VERSION "1.0" set_package_property GROUP "GroupName" set_package_property DESCRIPTION "A descripton." set_package_property ELABORATION_CALLBACK elaboration_callback set_package_property EXTRACTION_CALLBACK extraction_callback add_fileset synth_fileset QUARTUS_SYNTH fileset_callback "Quartus Synthesis Fileset" add_fileset sim_verilog_fileset SIM_VERILOG fileset_callback "Simulation Verilog Fileset" proc elaboration_callback {} { enable_all_instances } proc extraction_callback {} { extract_modules } proc fileset_callback { output_name } { generate_all_instances } Any help would be hugely appreciated, on this issue and on my general workflow.

Runtime flexibility is only valuable when it is reliable High-speed systems are being asked to do more with the same hardware. A data-center platform may need to operate as a single 400G Ethernet link in one deployment, then support multiple 100G links in another. A front-haul or edge system may need to adapt to different rates, protocol roles, or customer configurations over the life of the product. The promise is simple: deploy one platform, then adapt it as requirements change. But in high-speed design, changing a configuration is not the hardest part. Changing it correctly is. A live transition is not just a speed change. It can require coordinated updates across the the various networking layers, along with clocking, lane mapping, reset behavior, and link recovery. If those layers do not move together and in the right order, the result can be an unstable link, silent data corruption, or a system that hangs indefinitely waiting for CDR lock. That is the real value of Altera Dynamic Reconfiguration: it gives designers confidence that runtime transitions are clean, verified, and repeatable. The Altera difference: clean, verified transitions Altera Dynamic Reconfiguration is built around a profile-driven, silicon-aware flow. Designers define the target operating modes in Quartus Prime, and the system generates validated profiles for each supported state. At runtime, the Dynamic Reconfiguration Controller applies the selected profile through a managed, hardware-driven sequence. It orchestrates the transition across the full protocol stack, ensuring MAC, FEC, PCS, and PMA layers are updated in a coordinated and deterministic order, rather than leaving the designer to manually manage each step. The result: clean, verified transitions - no partial configurations, no unsequenced resets, and no user-managed state machines to debug at 2 a.m. This matters because the transition itself is often where risk appears. A system may appear to support multiple modes on paper, but if each layer must be independently controlled, reset, and validated by user logic, the design team carries the burden of proving that every edge case works under real operating conditions. Altera reduces that risk by turning reconfiguration into a controlled system operation. The selected profile is known, and the transition is repeatable. Silicon-driven confidence The assurance comes from the architecture. Agilex devices use hardened transceiver and protocol IP designed for high-speed operation. Rather than treating reconfiguration as a collection of ad hoc register writes, Altera Dynamic Reconfiguration works with hardened IP and validated profiles to help ensure that runtime switching happens in a controlled, silicon-driven way. That silicon foundation is especially important at 100G and 400G data rates, where small sequencing mistakes can lead to difficult debug cycles. When designers hand-craft transceiver reset state machines, getting the order right, the timing right, and the edge cases right can take weeks. With Altera, those critical sequencing responsibilities are built into the reconfiguration flow. The benefit is not just ease of use. Ease of use is a result. The primary benefit is trust: designers can enable live switching with greater confidence that the system will move from one valid state to another without glitches. A practical advantage for real systems In real deployments, flexibility has business value only if it does not create operational risk. Altera Dynamic Reconfiguration helps a single hardware platform support multiple configurations while avoiding the disruption of a full FPGA reprogramming cycle or duplicate hardware paths for every possible mode. For networking platforms, this can mean supporting different Ethernet configurations on the same physical transceiver resources. For multi-protocol systems, it can mean adapting a port role as requirements evolve. For platform owners, it means more deployment options from the same hardware design. This is where Altera has a practical positioning advantage: customers get runtime flexibility with more of the critical transition behavior handled by the platform. Instead of asking designers to manually manage every reconfiguration step, Altera provides a structured flow designed to produce predictable, verified results. What the demo proves The Agilex 7 400G Dynamic Reconfiguration demo turns this story into proof. In the demo, two Agilex 7 FPGA boards are connected over QSFP-DD, and the system dynamically switches between a 400G Ethernet configuration and multiple 100G Ethernet links using the same setup. The demonstration shows more than a mode change. It shows live traffic validation, link status, packet counters, error status, and FEC behavior during the transition. That is the point: the feature is not theoretical. It is running on silicon, switching in real time, and validating the kind of clean transition designers need before they trust the feature in production systems. Why this matters now As data-center, telecom, edge, and industrial systems become more configurable, customers increasingly need hardware platforms that can support multiple roles over time. The question is no longer whether a system can support more than one mode. The question is whether it can switch modes cleanly, predictably, and with confidence. Altera Dynamic Reconfiguration is designed for that moment. It combines hardened IP performance, profile-driven control, and coordinated sequencing to deliver runtime flexibility without compromising reliability. Dynamic reconfiguration is valuable because it enables flexibility. Altera makes it compelling because it makes that flexibility trustworthy.

Agilex® 9 Direct RF-Series FPGAs help system designers address two critical RF system priorities: lower latency and improved SWaP (size, weight, and power). By integrating high-performance RF data converters directly with FPGA fabric, Agilex 9 Direct RF-Series FPGAs can reduce RF-to-baseband latency, simplify the signal chain, lower system power, and free up valuable board space for future capabilities addition. In a draft comparison of discrete JESD-based architectures versus an Agilex 9 integrated Direct RF approach, the integrated solution showed up to 78% lower latency versus a JESD204C discrete solution and up to 86% lower latency versus a JESD204B discrete solution. The comparison also showed approximately 40% lower power consumption and up to 48% board-area reduction. These gains support both primary value propositions: faster system response through lower latency, and better SWaP through fewer external components, lower power, and a smaller, more efficient RF design. Digital radio frequency memory (DRFM), electronic attack, and electronic protection are good examples of applications where latency improvements can make a meaningful difference. In these types of RF systems, lower RF-to-baseband latency helps systems act on complex signals faster, improving responsiveness, timing precision, and mission effectiveness in contested electromagnetic environments. The SWaP benefit is also critical in long-lifecycle aerospace and defense platforms which may remain operational for decades, yet have limited space, weight, power, and cooling capacity for new hardware. As signal environments evolve, these platforms need room to add or upgrade capabilities without major system redesigns. By integrating RF data conversion with FPGA processing, Agilex 9 Direct RF-Series FPGAs can help system designers improve responsiveness, reduce board area, simplify the RF signal chain, and create more headroom for future upgrades.

New DDR5-6400 support delivers a 14% increase in maximum DDR5 data rate, strengthening Agilex® 7 M-Series device’s memory leadership on a production device family. This effort reflects Altera’s continued investment to improve features on platforms already in volume production. For customers building high-performance FPGA-based systems, memory capability is a core platform requirement, and the level of memory performance increasingly shapes overall system differentiation. That is why this latest Agilex 7 M-Series enhancement matters. With DDR5 support increasing from 5600 MT/s to 6400 MT/s, Agilex 7 M-Series devices support a 14% increase in maximum DDR5 performance on a device family already shipping in production. The significance of this update goes beyond speed alone. It reinforces a broader story about platform value: more usable bandwidth, better system efficiency, and continued innovation on a platform customers can design around today. More bandwidth, better system efficiency DDR5-6400 is not just a higher interface number. It enables more memory bandwidth from the same platform, helping customers move more data through bandwidth-intensive designs. That added bandwidth can also improve bandwidth density at the system level. In practical terms, it can help designers reach target throughput with a more optimized memory subsystem, potentially reducing DIMM or channel requirements in some designs and improving overall platform efficiency. Those advantages become increasingly important in the kinds of applications Agilex 7 M-Series devices are built to address. Across AI, networking, video processing, and data center infrastructure, system performance depends not only on compute capability, but also on how efficiently data can be moved and sustained through the platform. A broader production-ready platform advantage This update also says something important about the platform itself. Agilex 7 M-Series devices already offer production-ready support for advanced external memory technologies, and DDR5-6400 extends that advantage further. As next-generation infrastructure platforms evolve for AI, scale-out networking, and data-intensive acceleration, advanced memory capability is becoming an increasingly important platform differentiator. DDR5 support is now emerging across a broader range of FPGA segments, including mid-range devices such as Agilex 5 and even power- and cost-optimized devices such as Agilex 3 (with LPDDR5 support). Agilex 7 M-Series devicesbrings DDR5-6400 to a high-end FPGA platform tier built for larger, more data-intensive AI, networking, and infrastructure applications. By combining advanced memory performance with substantially greater logic capacity, it delivers differentiation at the platform level. This enhancement is enabled through an upcoming release of Quartus® Prime Pro Edition and is designed to be backward compatible with previously shipped silicon and boards. Customers interested in enabling DDR5-6400 should contact Altera for additional guidance on supported configurations, applicable speed grades, and implementation details. Conclusion The move to DDR5-6400 on Agilex 7 FPGAs and SoCs M-Series delivers a 14% improvement in maximum DDR5 data rate, improving bandwidth density and system-level efficiency while extending the value of a production-ready platform for evolving customer requirements.
