Schematic net/inst name mapping: case-insensitive to case-sensitive

tweeks
Here's a fun SKILL problem to chew on:

I have a tool that reads SPF (Standard Parasitic Format) files and spits out case-INsensitive hierarchical net and instance names. I want to probe them in Virtuoso Schematic Editor (latest version) using geAddNetProbe().

Problem: how to map the case-insensitive names from the SPF tool like this

"/rtop/r<0>/rdb<0>/decovst/nd_share"

to names that will be recognized by geAddNetProbe() like this:

"/rtop/r<0>/rdb<0>/DECOVST/nd_share"

(in this case, "DECOVST" is in upper-case in the Virtuoso schematic.)

You can assume there will never be a schematic with two instance or net names differentiated only by case.

I'd like to avoid traversing the entire hierarchy to build a mapping table of every instance and net name, but as I comb the SKILL docs, it's starting to look like there is no other way....
