So do I!!

I have met the same problem as you, and I have tried to modify the ptf document, but I failed.

And now I am trying to write a interface which can change the asynchronous timing to synchronous timing, and then from the Nios avalon bus, the SSRAM works as ASRAM.

But I still think that to modify the ptf is the best method to make it works.

Can anyone tell we how to do it??

thinks!!
