I've heard it's used a lot in EE design software (PCB design, or FPGA as you mentioned). My experience with Tcl is as part of Altair's suite of mechanical simulation (FEA, MBD, etc) software, which is quite popular in aerospace and automotive. It has its warts (associative arrays) but it's still a neat little language. EIAS actually works pretty well as an abstraction tool. I'd take it over VB (eg, excel VBA) anyday as a macro/automation language.
