Critical Issue
Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.4, you may find functional failures or bit-errors on Periphery-to- Core (P2C) paths when using the PHY Lite for Parallel Interfaces Intel® Agilex™ FPGA IP. This is because the timing of the P2C transfers paths is not analyzed.
This problem only affects P2C transfers within PHY Lite for Parallel Interfaces Intel® Agilex™ FPGA IP.
There is no workaround to this problem but a patch is scheduled to be released.
This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
