why did these companies choose Tcl over Python

That is correct. Tcl has it roots at UC Berkeley and was originally
to provide a command line interface for electronic design automation
Most commercial EDA vendors at that time were using their own,
command language. Only later became Tcl widely adopted among EDA
and -even more important- among users, electronic designers.
There is a large base of Tcl scripts in existence among users.
that is practically and commercially simply not feasible regardless of
the strengths or weaknesses of Tcl vs any other language.
Recently, Python is getting more traction inside EDA, especially for
internal use and internal development and in some cases as the design
language of newer EDA tools.
