Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 19.3, you may see this error during synthesis. This error occurs in designs that include embedded memory IPs with the RAM_BLOCK_TYPE set to M20K and has been upgraded from version 19.2.
The following embedded memory IPs are affected
- RAM: 1-PORT Intel FPGA IP
- RAM: 2-PORT Intel FPGA IP
- RAM: 4-PORT Intel FPGA IP
- ROM: 1-PORT Intel FPGA IP
- ROM: 2-PORT Intel FPGA IP
Only designs targeting Intel® Stratix® 10, Intel® Arria® 10 and Intel® Cyclone® 10 GX are affected.
To work around this problem, either recreate the RAM IP in version 19.3 or upgrade the IP from version 19.1
This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
