From the (little) I've seen of that world, I'm not sure the EDA vendors understand Tcl very well either; I wouldn't want to work with scripts for Cadence's schematic capture tool, and that's not because of Tcl, it's because their scripting interface is a disaster. (Exposing C++ iterators at the script level, for example.)

Ironically the schematic capture scripts were likely written in SKILL (LISP-like language) and not TCL.

SKILL is much better than TCL for data processing. TCL's strength is in command control flow.
