Extraction shorts vs LVS shorts

[karthikshetty]

Hi,
Can anyone please explain the major differences between extraction short and LVS short in physical design?

Thanks in advance

Is this question from an interview? I mean, it is pretty vague as it is.

We call extraction shorts as layout shorts. Layout shorts are PG Shorts and port-to-port shorts, whereas lvs shorts include all types of shorts like PG, signal, and clock shorts. It is good practice to first clean up all layout/extraction shorts and then to check for LVS issues otherwise the LVS report will pop up lots of violations and are difficult to debug.
