[MIG] Where to find memory initialization info/log?

Jump to solution

PG150 has detailed info on memory calibration esp. read & write training. However, there is little info found on PG150 about memory initialization (MRS cmds, ZQ cal etc.). It even says "Memory IP designs never issue a calibration failure during Memory Initialization".

Is there a way to read the memory initialization info or log? I want to find out the info on CAS latency, Writing latency, ZQ calibration etc.

Hello @adieux ,

 

Please check the MR register in the XSDB log or you could check the MR regiters in the RTL.

Do you want to check the Mode reigsters settings? You can run simulation to find out and check they're the identical with the values you set in IP wizard.
