Why are there intermittent calibration failures in the External Memory Interfaces Agilex® 5 FPGA E-Series IP?
Description Due to a problem in Quartus® Prime Pro Edition Software version 25.3.1 and earlier, you may run into intermittent EMIF calibration failures on LPDDR4 1CHx32, 2-Rank configurations running at 1333 MHz on Agilex® 5 FPGA E Series devices. Resolution To work around this problem, disable cross-rank delay averaging by enabling the following debug flag in the parameter table: DBG_CFG_DISABLE_RANK_AVG_AND_OVR This prevents the firmware from averaging DQS-WR delays across ranks, which eliminates the invalid delay setting that causes the MGN-stage calibration failure. Note: Disabling rank averaging may affect traffic stability in some configurations. A patch is available to fix this problem in Quartus Prime Pro Edition Software version 25.3.1. Download and install the below 1.04 patch. This problem has been fixed beginning with version 26.1 of the Quartus Prime Pro Edition Software.Why does Board Support Package (BSP) Editor in Quartus® Prime Pro Embedded Edition fails to generate Nios® V processor BSP project from .vds file?
Description Due to a problem in the Quartus® Prime Pro Embedded Edition Software version 26.1 and 26.1.1, the BSP Editor fails to generate Nios® V processor BSP project from .vds file. This issue is not affecting BSP project generation: From .qsys file using BSP Editor in Quartus® Prime Pro Embedded Edition software, or Using BSP Editor in Quartus® Prime Pro Edition software. This issue is caused by a software bug in the BSP Editor of Quartus® Prime Pro Embedded Edition software. Refer to Nios V Embedded Processor Design Handbook - Recommended Tools from Quartus Prime Installer (PDF) for more information on the difference between Quartus® Prime Pro Edition and Quartus® Prime Pro Embedded Edition software. Resolution To work around this problem in the Quartus® Prime Pro Embedded Edition Software version 26.1 and 26.1.1, apply either one of the workarounds below: Switch from .vds to .qsys file Use BSP Editor in Quartus® Prime Pro Edition software version 26.1 or 26.1.1 This problem is currently scheduled to be resolved in a future release of the Quartus® Prime Pro Embedded Edition Software.Why is Agilex® 5 and Agilex® 3 FPGA External Memory Interfaces (EMIF) IP missing from the BSP Linker when the Nios® V processor Board Support Package is generated?
Description Due to a problem in the Quartus ® Prime Pro Edition starting since software version 24.1, the Agilex ® 5 and Agilex ® 3 FPGA EMIF IP is missing from the BSP Linker when generating the Board Support Package. This might occur for Nios ® V processor designs targeting Agilex 5 FPGA or Agilex 3 FPGA, that uses EMIF IP. This is because Agilex 5 and Agilex 3 FPGA EMIF IP are missing the isMemoryDevice agent information. Refer to Nios® V Processor Software Developer Handbook - Memory-Mapped Slave Information (PDF) for information about isMemoryDevice agent information. Refer to External Memory Interfaces (EMIF) IP User Guide Agilex® 5 FPGAs and SoCs (PDF) for information Agilex ® 5 FPGA EMIF IP. Refer to External Memory Interfaces (EMIF) IP User Guide Agilex® 3 FPGAs and SoCs (PDF) for information Agilex ® 3 FPGA EMIF IP. Resolution To work around this problem in the Quartus ® Prime Pro Edition in all the affected software version, apply either one of the following workarounds: Workaround 1: Manually add isMemoryDevice to the EMIF IP (in Platform Designer only) Select the s*_axi4 signal (mainband AXI4 from fabric to controller) that connects to the Nios ® V processor’s instruction/data manager. Right-click, and click Edit Component Instantiation ... Select s*axi4 and edit the Assignments. Enter new Key as embeddedsw.configuration.isMemoryDevice, and Value as 1. Save the new assignment. Generate a new BSP. Workaround 2: Manually define EMIF IP linker memory device Refer to the Nios V Embedded Processor Design Handbook - Defining Address Span Extender Linker Memory Device. The example demonstrates how to manually define Address Span Extender linker memory device. For this problem, apply the same procedure but on the EMIF IP directly. This problem is currently scheduled to be resolved in a future release of the Quartus ® Prime Pro Edition Software.
