Is there any knonw issue for simulation StratixIII Altmemphy DDR2?

Description

Yes. There's a bug in ALTMEMPHY when quick-calibaration mode is selected in the GUI that affects DDR2 params. Basically, one of the resync stages is disabled when it shouldn't be, which causes the sim to always fail.

 

Workaround/Fix

Workaround for the customer is to simulate using either skip-cal or full-cal mode. It would be fixed in 12.1
