Regular ContributorHi,
emif_usr_reset_n is an active low signal.
It's asserting when entering reset sequence then perform calibration.
local_reset_done is a active high signal.
It's asserting when the calibration is done.
According to the initialization flow, the memory will run a calibration first before it's able to accept command from user logic.
Therefore, the emif_usr_reset_n should be trigger first.

Occasional ContributorJust to make sure i understand it correctly, please confirm:
1) after user issues reset_request, which of the two signals go high first:
emif_usr_reset_n
local_reset_done
2) When these signals go low to high, it means that IP is out of reset. is that right?
thank you.
