Hi,

I would like to know if fixing DRC and LVS impacts timing in any way. Is there a chance that it might degrade setup/hold timing?How exactly they are related?
 

It may impact timing. Suppose you have open net (not fully routed) - it is LVS error. So, the parasitics (especially resistance) of this wire will be inaccurate, so the timing will be wrong.

DRC errors - space between wires (or cells) or not enough metal density or other violations - all of these may impact RC of the wires - impact timing.

One could argue that measuring timing doesn't make any sense if it is not DRC clean.
