Retaining group membership when copying fig group objects with "Transparent Group" set to "ON"

Jeff Lucas

I was using an older version of Virtuoso - Layout up until a few months ago.  The behavior with that previous version when copying wires, vias, etc. contained within a fig group, but operating from the top of the cell layout hierarchy with the "Transparent Group" icon clicked on, was for the copied object to inherit fig group membership from the source object of the copy.  I.E. - when turning off "Transparent Group", afterward, you had to descend into the copy-source fig group to be able to select that new object.  For whatever reason in the new version (ICADVM20.1-64b.500.17) and our company's default settings, now the new object doesn't inherit the group membership from the copy reference object, subsequently is not part of the source's fig group, and appears as if it were created at the top level.

Question - is there a setting somewhere that controls this behavior so that I change it to be able to get copied objects in this scenario to inherit the group membership of the reference object?

    envSetVal("layout" "keepCopiedInsideGroup" 'boolean t)

    will do this. My guess is that this was set in your previous environment - I don't think it was ever the default.
