Tcl is a household name in the field of EDA tool scripting. Virtually all software tools designed by Cadence, Synopsys, and Mentor include a Tcl REPL/console. Any task performed in the GUI is actually executed in the REPL, making it easy to replicate a specific flow by just copy/pasting the commands displayed in the REPL into a Tcl script. To load a script, you simply pass it as an argument when running the software.
