Calibre How to check for poly jumpers using “soft” connectivity for DRC

Poly jumpers are sometimes used in layout to form a connection where there isn’t enough room to make a more robust connection with metal. In some processes though, poly resistance can be high enough that jumpers like this are undesirable or not allowed.

This video uses an example layout to demonstrate some high level ideas related to checking for poly jumpers with Calibre nmDRC.

Specific SVRF code examples can be found in the Calibre Verification User’s Manual.
