Anyway to Speed up simulation time for DDR2 Controller?

Hi, Is there any trick to speed up simulation time for DDR2 Controller? It takes me 40mins from start until LOCAL_INIT_DONE is asserted which shows memory has been initialized. Is there anyw...

Are you interested in a full scale simulation? are you testing the DDR2 controller or something that connects to it?

You could try writing a bus functional model of the DDR2 controller - that would give massive speed ups.

Hi,

Thank you Tricky . I'm testing my logic which is interfacing to the local_ side of the DDR Controller.

It's okay to have slow simulation but the thing is that it spends 40 minutes just to complete initialization, then i can start access the DDR2 controller !!! (I wonder why I need to initialize that long for functional simulation???)

There should be a better way, right?
