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

    Andrew, Thats a valid point you have stated. However, if I start from the topCellView, the search space would be greatly reduced. However, if there are multiple instances of the current cellView, the same problem remains of identifying which one of them I am currently in. (This is what I understand). Thanks anyways for the previous solution. Regards, Atul
