Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.1, there might be a hardware test failure related to the Capture strobe phase shift setting for the PHY Lite for Parallel Interfaces Intel FPGA IP at all supported frequencies when targeting the Intel® Agilex® 7 device. The hardware test failure may be observed when the Capture strobe phase shift is set to:
- Any value for interface frequencies less than 150 MHz.
- Any value other than 90 degrees for interface frequencies of 150 MHz or more.
Due to this failure, interface frequencies below 150 MHz are not supported in the PHY Lite for Parallel Interfaces Intel FPGA IP. The minimum interface frequency must be 150 MHz.
For the supported interface frequencies, the Capture strobe phase shift is fixed to 90 degrees in the PHY Lite for Parallel Interfaces Intel FPGA IP GUI.
For the Intel® Quartus® Prime Pro Edition Software version 21.1 and later, it is recommended to use Capture strobe phase shift values other than 90 degrees to use dynamic reconfiguration.
For more details, refer to PHY Lite for Parallel Interfaces Intel® FPGA IP User Guide, Dynamic Reconfiguration section.
For the Intel Quartus® Prime Pro Edition Software versions 20.4 and 20.3, there is no hardware support enabled for PHY Lite for Parallel Interfaces Intel Agilex® 7 FPGA IP.
This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 21.3.
