Ddr4 command address parity error

WebJun 8, 2016 · The controllers' DDR4 command/address (CA) parity and write cyclic redundancy check (CRC) with retry features provide data and command/address integrity, allowing the system to recover from a command or address error by returning to the last known good state and retrying the failed command. WebFollowing the "UltraScale Architecture-Based FPGAs Memory IP v1.4 PG150 June 30, 2024" it shows a port called mc_PAR for RDIMMs and LRDIMMs. As far as I understand this partiy bit is for the encoding of the command and the address (CA parity). For some reason it is not showing in my IP.
