Course preview: Tcl scripting for FPGA engineers

This is a preview of some of the lessons of the new Tcl course.

The Tool Command Language (Tcl) is the scripting language that goes hand in hand with VHDL. That’s because most FPGA software tools use this language. For example, Vivado, Quartus, Questa, and ModelSim.

You can create powerful scripts for any of these tools when you know Tcl. But Tcl isn’t like other programming languages. A major point of confusion for new learners is that everything is a string in Tcl, and I will explain what that means in the first lessons.

If you already know Tcl, there are still many things you can take away from this course. For example, the details of how namespaces, variable scopes, and classes work.

Finally, we will use Tcl to create a GUI widget for Questa/ModelSim. And you will see how we can interact with VHDL simulations and visualize the state of the DUT using Tcl as a front-end.
