Your hardware design made easier, more efficient and more fun


A basic text editor just won’t do if you want to write VHDL code like a pro. Sigasi Studio is an intelligent VHDL design tool that offers advanced design assistance. Why walk if you can drive… or get driven to your destination?

More efficient

Sigasi Studio guides you through complex code designs. With instant feedback on errors and auto-completion suggestions. Reducing development times and helping you and your team write better VHDL code.

More fun

Our secret ingredient is the super fast built-in compiler. Because Sigasi Studio understands your code while you type, it can help you be more productive, produce higher quality work and have fun in the process.

VHDL code editing

Code completion, based on where you are in the code including component instantiation. Seconds after you type a line of code, Sigasi Studio marks your syntax errors so you can fix them right away. The code is formatted and beautified consistently.

VHDL code browsing

Sigasi Studio serves as a VHDL code browser, so that you can navigate through your designs to understand large and complex legacy designs. With graphical browsing you can create visuals of your code, updated instantly and cross-linked to your code.

VHDL code checking

See errors while you type and get warnings about dubious code. Save time and money as you need less time to write better VHDL code and you are able to free up valuable time at code reviews.

Sigasi at a glance


Our programs offer a standard way of doing things. But if that doesn’t fit your requirements, you can create a custom workbench, suited for you specific needs.


Built on the Eclipse framework, available both as Eclipse plugin and a standalone application.


You have complete freedom in setting up a project. If it’s installing plugins for other languages, version control or issue tracking.

Error highlighting

The number one time-saver for a lot of our clients: Sigasi Studio checks your code while you are typing.

Power navigation

Sigasi Studio’s built-in compiler knows the meaning of each word in your code, even if it’s declared in a different file. This works for all objects in your design.
