Your hardware design made easier, more efficient and more fun


A basic text editor just won’t do if you want to write VHDL or SystemVerilog code like a pro. Sigasi Studio is an intelligent 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 time and helping you and your team write better VHDL and SystemVerilog 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.

Code editing

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

Code browsing

Sigasi Studio serves as a VHDL and SystemVerilog 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.

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 and SystemVerilog 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 are free to choose your own project structure, install other plugins, use any language, version control- or issue tracking system.

Forever free

Sigasi Studio Starter is a great editor for everybody. It beats all existing VHDL editors, and it is available for free.


If the manual or the tricks available on the Insights-section of our site are not enough for you and your team, there are several ways in which we can help you train. Ask us!


Our Educational licenses are free too. Sigasi Studio is used in hundreds of universities as teaching and learning tool by thousands of students and professors.

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.

Well formatted

Save time by typing less. Keep your code clean and well formatted. Our templates only show up where they are legal.




“Sigasi is great tool for designers who want to spend more time coding instead of typing.”

Johannes Vanoverschelde


“The “Net Search” feature of Sigasi Premium boosts my productivity greatly because with it I save a lot of time navigating around the design that I can use to do actual work!”

Kenneth Macpherson
