Ignore dummies in PVS using GPDK 45nm [solved]

hesaliveJim

I would like to Ignore dummies when performing LVS using PVS.

I'm using the virtual foundry GPDK 45nm (Cadence) to do some research.

I note in this post:

https://community.cadence.com/cadence_technology_forums/f/custom-ic-skill/58057/cdsenv-setting-with-backannotation-in-layoutxl/1393995#1393995

BrendaGray suggests:

lvsIgnore: When set to "true" or checked, it indicates that the dummy should be ignored during LVS checks.

This would do but I'm not sure where to place it within the PVS submission form:

I tried putting it in the Filter options shown above but it is complained and should it be lvsIgnore=TRUE wherever it's put?

I do know that a lot of designers recommend simply updating the schematic but as this is a 'virtual foundry' I see no harm -  in Calibre the option exist.

  • I don't have time right now to answer this properly, but I did want to say that I believe the post from BrendaGray was generated by something like ChatGPT (I did some searching at the time and found a number of other posts in other forums on totally different topics which also looked machine-generated). The text in that append is not entirely correct and it looks wrong in a way that only an LLM might produce rather than a real human!
