15 years agoEPCS contraints in TimeQuest
I have created an SOPC Builder module and added the EPCS core. Can anyone provide an example or point to some documentation that shows how I should constrain it in TimeQuest? For example, should I treat it as a source synchronous output? Should I constrain the EPCS I/O to the EPCS clk?

Thanks for the response. I did run into that old post. I wasn't sure exactly how relevant it was considering it was addressing the ALTASMI_PARALLEL megafunction. The last comment on that post was from someone basically saying don't worry about it.
I still somehow feel like I should be constraining the EPCS signals. - Altera_Forum

I don't know if TQ constrain for epcs i/o is strictly required. Probably the i/o frequency is low enough and it will always meet the timing.
Anyway you find some information in AN523 and in the following thread http://www.alteraforum.com/forum/showthread.php?t=20938
