Cyclon 5 tampering protection bit
I have a cyclone V with an AS scheme. I have generated an key-file (ekp) with tampering protection bit set according to AN556 Then I open it in the programmer programmer and generate a jam-file now in the jam-file the procedure DO_KEY_SECURE is optional which means I have to enable that procedure manualy with "-e DO_KEY_SECURE" in the command, for example: quartus_jli -c <n> keys.jam -e DO_KEY_SECURE -a <action> is it possible to make this procedure non-optional so it will program the tampering bit by default when programming the key?31Views0likes3CommentsTranceiver Enhanced PCS Basic mode questions
Hello Guys, We used Arria GX and Straitx IV GX devices before, now we switch to use Cyclone 10 GX FPGA. I have several simple questions about XCVR's control port/signal. Why I can't see rx_control and tx_control ports when I make "Enable simplified data interface" ON? In basic or custom mode, 1 bit control signal corresponding 8-bit parallel data bits. I read XCVR user guide, it seems that only LSB 2-bits of the control bus will be used to recognize/indicate data word or control word?203Views0likes14CommentsWhy does the F-Tile JESD204C FPGA IP Example Design fail to generate when the data rate above 23 Gbps with a target development kit selected, showing an error requiring VSR_MODE_HIGH_LOSS even though this option is unavailable in the IP GUI?
Description Due to a problem in the Quartus® Prime Pro Edition software version 25.3, the VSR_MODE_HIGH_LOSS option was removed. User is expected to use VSR_MODE_LOW_LOSS instead, which provides the same functionality previously available in both modes. However, this change is not correctly reflected in the F-Tile JESD204C IP GUI. Resolution To work around this problem in the Quartus® Prime Pro Edition software version 25.3, download and install the patches below. This problem is fixed beginning with the Quartus® Prime Pro Edition software version 25.3.1.Why is the maximum number of I/O PLLs incorrectly reported in the Total PLLs Fitter Summary report?
Description Due to a problem in the Quartus® Prime Pro Edition Software version 25.1.1 and earlier, you might see that the maximum number of I/O PLLs for Agilex® 5 FPGA devices is stated incorrectly in the Total PLLs Fitter Summary report. Resolution The compilation will pass as long as the number of I/O PLLs used in the design does not exceed the actual maximum number of I/O PLLs supported by the specific device. The correct maximum number of I/O PLLs supported can be checked from the PDF with the title of Agilex 5 FPGAs and SoCs <Series> Product Table. This problem is fixed beginning with the Quartus® Prime Pro Edition Software version 25.3.Why is there "sopcinfo2swinfo.exe: command not found" when running sopc-create-header-files under WSL, or Docker under Windows?
Description An error message like this: sopc-create-header-files: line 182: sopcinfo2swinfo.exe: command not found sopc-create-header-files: sopcinfo2swinfo.exe --input=./peripheral_subsys.sopcinfo --output=/tmp/sopc-create-header-files.1312.tmp.swinfo failed will be seen in the Quartus ® Prime Pro Edition Software version 25.3.1 and earlier, when using the sopc-create-header-files script within the Linux version of the Quartus ® Prime Pro Edition Software, running on the Microsoft* Windows operating system. The Linux version of the tools can be installed under Windows* using WSL, WSL2 or Docker. In all of these cases, the sopc-create-header-files script detects that it is running under Windows* and looks for an internal tool with the suffix “.exe”. However, since the Linux version has been installed, the tool does not have that suffix and so cannot be found by the sopc-create-header-files script. Resolution To work around the problem, either switch to using a Windows* installation of the Quartus® Prime Pro Edition Software, or follow these steps to continue using the Linux installation under Windows*: Under Linux, use the command “which sopc-create-header-files” to find the location of the script. Copy the script from this location to another location of your choice. Make the newly copied script version writable using the command: chmod +w <path to newly copied script> Modify your newly copied script version. Find the following line: windows_exe=.exe and either remove it or add a single # symbol at the start to comment it Use your newly modified version of the script instead of the installed version. This will now execute correctly.Why there is Missing location assignment warnings on hps_io interfaces (SDMMC, UART, I3C) in Quartus® Prime Pro Edition Software version 25.1.1 and earlier?
Description Due to a problem in Quartus® Prime Pro Edition Software v25.1.1 and earlier. You might see the warnings messages “Missing location assignment” on some of the hps_io interfaces due to the mismatch interface name. Resolution This problem is resolved in Quartus® Prime Pro Edition Software v25.3.Why does GD55LB02GE QSPI flash fail in Linux* in FPGA SoC device?
Description If you use Linux* version between socfpga-6.0 and socfpga-6.12.43-lts with GD55LB02GE QSPI flash, you may fail to mount the file system in Linux if it’s stored in GD55LB02GE. This is caused by the gigadevice.c in these versions. Resolution This issue is fixed in socfpga-6.12.43-lts and afterwards. You can upgrade Linux source code to this version, or comment out the GD55LB02GE entry in gigadevice.c in old versions.Why is the HPS Xen Hypervisor GSRD for the Agilex™ 5 FPGA E-Series Premium Dev Kit not supported in release 25.3.1?
Description Due to the gradual GSRD migration from legacy (GSRD 1.0) to Baseline (GSRD 2.0) for the Agilex™ 5 FPGA E-Series Premium Dev Kit, the Legacy GSRD to boot from SD Card was deprecated in release 25.3.1. Since the Xen GSRD still makes use of Legacy GSRD, this is not supported in this release. Resolution There is not a workaround for this problem, but you can still use the latest Xen GSRD available from release 25.3: HPS Xen Hypervisor GSRD for the Agilex™ 5 FPGA E-Series Premium Dev Kit. This problem will be fixed in a future release once the Xen GSRD gets ported to use the Baseline GSRD. Additional InformationCannot enable SPIM0 and SPIS0 routing to FPGA at the same time. Disable one of these in Advance FPGA Placement
Description The Quartus Prime software does not allow the routing of both the SPI master (SPIM) and SPI slave (SPIS) interfaces to the FPGA fabric simultaneously for the same SPI instance. This restriction applies to SPIM0/SPIS0 and SPIM1/SPIS1. Resolution When configuring SPI routing to the FPGA, enable either the master or the slave interface for each SPI instance, but not both at the same time. For example: SPIM0 and SPIS0 cannot be enabled together SPIM1 and SPIS1 cannot be enabled together

Quartus® Prime Pro Edition 2026.1.1 expands memory options across the Agilex® FPGA portfolio. Memory is increasingly setting the performance, power, and lifecycle limits of modern systems. AI acceleration, packet processing, storage, video, industrial automation, and edge computing all depend on moving large amounts of data efficiently. At the same time, memory availability and vendor transitions can force design teams to revisit component choices long after a platform architecture has been selected. With Quartus® Prime Pro Edition 2026.1.1, Altera expands memory options across the Agilex portfolio. The release brings higher-speed DDR5 and LPDDR5 options to Agilex 7 M-Series FPGAs and SoCs, broadens component choice through documented LPDDR5X device support, and extends LPDDR5 support to Agilex 3 FPGAs and SoCs. Together, these enhancements give designers greater flexibility to balance performance, power, footprint, memory cost, and supply continuity. What is new with Quartus Prime Pro Edition 2026.1.1 Enhancement Customer value DDR5-6400 and LPDDR5-6400 on Agilex 7 M-Series devices Higher Memory Bandwidth Raises the maximum supported memory data rate from 5600 to 6400 MT/s, an increase of more than 14%. DDR5 delivers up to 204.8 GB/s of aggregate bandwidth, while LPDDR5 provides a lower-power, compact-footprint option for bandwidth-intensive designs. LPDDR5X device use in LPDDR5-compatible mode New Sourcing Option Adds sourcing flexibility when LPDDR5 availability, or component strategy favors an LPDDR5X device. LPDDR5 now available for Agilex 3 devices New Memory Support Added Brings a modern low-power memory option to power- and cost-optimized Agilex 3 device configurations. Two 6400 MT/s paths for high-performance systems Agilex 7 M-Series FPGAs and SoCs already combine high logic density, high-speed connectivity, and advanced external memory functionality in a device family available today in full-volume production. Quartus Prime Pro Edition 2026.1.1 strengthens that family’s offering with DDR5-6400 and LPDDR5-6400 in approved configurations. For DDR5, the move from 5600 MT/s to 6400 MT/s increases the maximum data rate by more than 14%. That additional throughput can help AI, networking, storage, and infrastructure designs sustain higher data movement without expanding the FPGA footprint. It can also give architects more flexibility in how they meet a target bandwidth, including the potential to optimize channel count, DIMM selection, board space, and subsystem complexity when the application and supported configuration allow it. LPDDR5-6400 brings a second option to the same top-line interface rate. LPDDR5 is increasingly relevant beyond mobile products because it combines strong bandwidth with lower I/O power and a compact board footprint. Those characteristics are valuable in embedded systems, smart network interface cards, industrial platforms, edge compute, and other designs, where thermal limits and board area matter alongside performance. The result is a high-end FPGA platform that lets designers choose between DDR5 for capacity and server-class memory options, or LPDDR5 for power and footprint efficiency, while reaching up to 6400 MT/s and 204.8 GB/s of aggregate memory bandwidth in selected Agilex 7 M-Series device configurations. LPDDR5X device compatibility adds practical supply-chain flexibility The LPDDR5X enhancement addresses a different customer need. LPDDR5X devices are backward compatible with the LPDDR5 interface, so components can be used with an Agilex LPDDR5 memory interface while operating at the same speeds, voltages, and specifications as the LPDDR5 configuration. Customers can now design with LPDDR5X components in LPDDR5-compatible mode with greater confidence, backed by documented Altera support process. A complete memory offering across the Agilex portfolio Because the Agilex portfolio spans high-performance, mid-range, and power- and cost-optimized devices, customers can carry a consistent FPGA architecture and Quartus development flow across products with very different memory requirements. That continuity helps reduce redesign effort and gives engineering teams more freedom to scale compute, connectivity, and memory together. Teams can preserve DDR4 or LPDDR4 where product requirements, temperature range, or supply conditions still favor those technologies. New designs can move to DDR5 or LPDDR5 for higher bandwidth and better system efficiency. LPDDR5X device compatibility provides an additional sourcing path without requiring customers to redesign a separate memory interface. Explore Agilex FPGA external memory solutions and review the Quartus Prime Pro Edition 2026.1.1 documentation for supported devices, speed grades, memory components, and configurations.

A customer recently shared with me an interesting way they viewed the updated Altera brand: It’s like a long-time friend who had moved away for a few years but is now back and it’s time to get caught up. One of the things customers might want to 'catch up' on is Altera's efforts with regards to AI. It started when early FPGA products included the first basic digital signal processing (DSP) circuits within the FPGA fabric to improve performance for math-based logic, such as Fast Fourier transforms (FFTs) and finite impulse response (FIR) filters. These early enhancements improved general purpose FPGA-based computing but since 2015, our focus has shifted to improving AI capabilities in both silicon and software tools. DSP capabilities have gotten more sophisticated (fixed point, floating point, small and large bit precisions, etc.) and the quantity of available DSPs within a single device, have increased dramatically. Modern FPGAs are now capable of handling complex equations, especially those needed with the introduction of AI. This historical reminisce catches us up all the way until today’s news, where the latest Altera FPGA family is now broadly available to any customer who wants it; Agilex™ 5 SoC FPGAs, the first FPGAs infused with AI tensor blocks throughout the FPGA fabric. A short list of features that would be attractive to embedded or intelligent edge applications include: For those haven’t heard about Agilex™ 5 devices before today, here is how you can get started: Learn about the family. Review technical details. Download FPGA software. Free for anyone wanting access to Agilex™ 5 E-Series devices: Download Quartus® Prime Pro Test drive hardware (generally available now, lead-times may apply, via franchised distributors): Buy Altera development kits or 3rd party boards and SoMs The initial wave of board/SoM options include 9+ variants, with more coming. Evaluate AI or embedded options: Test out the FPGA AI Suite. Contact Altera sales for limited time introductory pricing. Utilize 3rd party tools (Arm DS, MathWorks) to design for the new, best-in-class Arm dual-A76 + dual-A55 based SoC subsystem or RISC-V based Nios® V soft IP processors. Altera is announcing the Agilex™ 5 family broad availability coincident with Embedded World 2024 because it is one of the key markets this mid-range FPGA family was architected for. Embedded customers clearly told us they perceive a lack of adequate compute in embedded processors, see a big need to fill security gaps, and want to add AI into their next generation systems. Agilex™ 5 devices can address all these concerns. Coming back to our initial topic, AI: GPUs are certainly a popular choice for AI training, but power consumption of GPUs for AI inferencing may be too high for intelligent edge or embedded applications. Instead of adding a separate GPU/AI semiconductor device to an embedded system (resulting in higher cost, more power, more thermal, etc.), why not add the AI function into an FPGA already planned to be used in embedded/edge equipment? For decades, FPGAs have been used in embedded/edge and communication systems for real-time control, IO connectivity, or image/data processing. The estimates on Agilex™ 5 device AI performance look good compared to equivalent class competitors. Because the FPGAs new DSP/tensor is implemented in a fine-grained architecture, it provides the FPGA designer the ability to tune for higher performance or lower power consumption, using the minimum amount of FPGA resources for the desired algorithm. Agilex™ 5 devices – AI key figures of merit: Tensor neural acceleration performance: Up to 26 / 56 TOPS ² Better performance per power efficiency versus embedded market inference GPUs. 1.7x higher frames per second per watt ³ Better raw performance versus other AI targeted FPGAs. 69% higher frames per second ⁴ There are many great reasons to look at this new family of FPGAs. If you are an architect, AI developer, or FPGA designer for embedded systems, don’t wait. As Mark Twain famously said, “The secret of getting ahead is getting started.” Don’t believe the marketing hype, try out your ideas in actual hardware, to see what is ‘possible’. Agilex™ 5 SoC FPGAs are just the latest phase in our DSP/AI journey. Altera, accelerating innovators. Come visit us at Embedded World 2024: Altera booth Hall 5, 5-135 and 5-136.
