design or timing problem with inclusion of chipscope core

Jump to solution

hello all,

 

 

Chipscope core is introduced in my design only for debug purpose.

 

later I wish to take it out... But my question is that if I include chipscope core, there will be definitely timing differences, I suspect including chip scope I intend to include more than 500 signals (collectively) to the chipscope core.

 

The reason is that the design is quite large, involving DDR3 communication block + algorithm implementation + address generation.... Hence I am worried about the performance with and without chipscope...i.e. if I debug my design (which I find very useful actually...) using chipscope but later if removed and it work differenly bcz of timing changes....

 

 

thank you in advance

Yes, the design will work differently without ChipScope.

Usually, the design will have better timing without ChipScope, but if (like 1 design I had) it fails STA when ChipScope is taken out, you just have to put it back in.
