    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, Verilog and SystemVerilog code.


    A basic text editor just won’t do if you want to write VHDL, Verilog 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?


    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 excel in your work.


    For VHDL users

    For Verilog and SystemVerilog users

    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 you can navigate through your designs to understand large and complex legacy designs. We create visuals of your code, updated instantly and cross-linked to your code, that allow graphical browsing.

    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.

    What customers love about Sigasi studio

    • Thank you for having such a robust product. I use Sigasi for a majority of my work day.
      It has increased my productivity immensely. I couldn’t imagine working on large projects without it. Sigasi’s automated block diagrams and state machines make my coworkers envious that they didn’t know about it sooner.
