What users say about Sigasi HDT

Coming from a software background and learning VHDL I saw that their tools for writing code were lousy. I feel very productive with this Sigasi HDT, spending less time on the little quirks of VHDL and focus more on design/logic.

— Jose J. Cuello (City College of New York)

First, the tool asks for a location of its workspace folder. The proposed default should be fine. After you should review and accept the license agreement, fill in the license key.

Step 4. Work on your existing VHDL project

Note: Using Sigasi HDT on an existing VHDL project is non-intrusive. At any moment, you can switch back to your current development tools. However, for your first experiments you may want to work on a temporary copy of your project.

On the welcome page, choose Point Sigasi HDT to an existing project. When asked for the project location, select the top level folder of the project. Your project is now ready to be used from Sigasi HDT.

If you use VHDL libraries other than work, you will need to configure these libraries.
