Occasional Contributorlocal_reset_done and emif_usr_reset_n on emif ip
Could someone please help me understand difference and relation between these two signals on the emif ip - local_reset_done and emif_usr_reset_n ? If I toggle local_reset_req to the ip, then local_r...

Regular ContributorHi,
local_reset_req (input)
local_reset_done (output)
local_reset_req has effect only when local_reset_done is high.
The local_reset_done signal transitions high once the calibration is completed.
Once the reset is requested (local_reset_req = high, for at least 2 EMIF core clock cycles), the EMIF interface will enter reset sequence (local_reset_done = low).
Then the core reset signal (emif_usr_reset_n) is driven low. The emif_usr_reset_n is active low signal.
After the reset sequence is done, local_reset_done is driven high again.
Regards,
Adzim

Occasional ContributorThank you for replying. But my question was which one of the two - emif_usr_reset_n, local_reset_done - goes high first?
or do they go high at same time?
