hello, i am violating setup when concatenating my design into user_project_wrapper. i tried reducing the frequency 10 times but the setup slack didn't change at all. Can someone help me?

@teolinhka I think the correct way, is to set timing constraints on your macro ports before you synthesize the macro. However, I can’t give you any advice on how to do that. The default

user_project_wrapper

config does not make any timing changes because

SYNTH_ELABORATE_ONLY

is set to

1

. What you might try is not using a macro, but synthesizing the top level. You’ll need to change your config file. There have been designs that. Maybe someone on the channel can share their config file.

Can I change SYNTH_ELABORATE_ONLY of user_project_wrapper to 0?

I searched through all the config files I have access to, but I couldn’t find an example where

SYNTH_ELABORATE_ONLY

was

0

.

but the setup on my design are still positive. Only when plugged into the wrapper does it become negative. I still haven't found a way to fix it.

Can anyone suggest timing constraints on the macro so that setup violations won’t occur at the top level? Or is there some other way to handle this?

I think I will have to edit the .sdc file to fix this error. Can anyone suggest an idea for me?
