Is tcl script language used in Modelsim?

--- Quote Start ---

Modelsim provides friendly GUI. But it can also be operated through script language. I wonder whether it is tcl script language? And anybody can provide some good tutorial?

Both Modelsim and Quartus can be controlled from Tcl scripts.

For an example, see this tutorial here:

The Quartus scripts are called synth.tcl, while the Modelsim scripts are called sim.tcl.

But I should first understand the tcl script language, right?

It certainly helps to know the syntax if you're trying to write your own script. However, its syntax is similar to many programming/scripting languages, so if you've ever written code, you should be able to follow the logic of a Tcl script.

Take a look at the scripts, run them to see what they do, and then read them to see how they are implemented.

Brent Welch, "Practical Programming in Tcl and Tk", is a pretty good book for learning the language.
