Skill code to get the selected instance's position (wrt topLevel) in the schematic hierarchy

Atul Dwivedi

Hi there,

As the subject suggests, there is a MOS in a subcircuit which I want to reference it to use it in extracting info during simulation like VDS etc.

Ex. a Mos named N0 is in the instance of the subcircuit named "inst1" which inturn is a part of a bigger subcircuit "Inst2" in the topLevel. So from the topLevel I would reference it like: "Inst2.inst1.XN0.M0". [Final use: .extract label=VDSN0 vds(Inst2.inst1.XN0.M0)]

The prefix of "X" and the suffix ".M0" I am able to obtain by some manipulation of cdf params, but I am stuck in finding the rest of the part (Inst2.Inst1).

If anyone could help, it would be nice.

Thanks and Regards,

Atul

    Hi Andrew,

    Thanks a lot. I just tested and I indeed needed exactly this.

    However, the assumption that the user will descend from the toplevel is obvious, but just in case someone (the user) opens the view separately, isn't there any fancy way to get the names of parent cellView and the parent above etc ?
