What's the difference between cellView~>prBoundary and cellView->shapes->lpp ?

Zelli

when lpp=list("prBoundary" "boundary") ?

 I mean, what's the cellView~>prBoundary supposed to do?

Thank you.

  • As Lawrence pointed out, prBoundary is now a specific object in OpenAccess, and tools that need a boundary (such as various parts of the Virtuoso Layout Suite, such as VLS-XL and the space based router, placers, etc, and also Encounter) will create such an object. 

    For example VLS-XL creates one when you do a generate all from source. Also you can create them manually with the Create->P&R Objects menu.

    No Cadence tool is using shapes on the prBoundary/boundary layer purpose pair any more.

    LEF will also use the prBoundary object.
