Why do I see SEU errors being detected consistently on my Agilex® 7 FPGA F-Series Development Kit (2x F-Tile) (DK-DEV-AGF023FA)? - Why do I see SEU errors being detected consistently on my Agilex® 7 FPGA F-Series Development Kit (2x F-Tile) (DK-DEV-AGF023FA)? Description Due to an issue with the settings of the Voltage Regulator LTC3888 used on the Agilex™ 7 FPGA F-Series Development Kit (2x F-Tile) (DK-DEV-AGF023FA), you may see SEU error being detected regularly when you enable SEU error check. The behavior occurs because the voltage required by Agilex™ 7 devices during operation, which can be between 0.7 V and 0.9 V, is over the VOUT_OV_WARN_LIMIT value programmed on LTC3888. Triggering the LTC388 to report an error back to the FPGA SDM. The SDM queues this error on the Error Message Queue (EMQ) which then asserts the SEU Error check. Resolution To solve this problem, you will need to reconfigure the Non-Volatile Memory registers of the Voltage Regulator using a Linear Technologies USB-to PMBus Controller ( DC1613A ) and Programming Adapter ( DC2086A ) and the Linear Technologies LTpowerPlay Software. Using the PMBus Controller and the LTpowerPlay software, configure the following Voltage Regulator configuration file linked at the bottom of this article and follow the steps lay out below: 1. Open the LTpowerPlay on a Windows computer. 2. Connect dongles as shown in picture, power up the board 3. Start LTpowerPlay. It will show a window like below: 4. Click "Open Project", browse to the project file, select it and click "Open". 5. Go to Utilities > Programming Utility. 6. Press OK when asked 7. In the LT Device Programmer, browse again for the project file: 8. Click "Program and Verify System" 9. Application will confirm all was programmed fine: Loading this file will configure the LTC3888 Voltage Regulator to operate within the required voltage range and allow the Agilex™ 7 device to operate with getting assertions from false errors.
