Sigasi Studio

Create, Integrate, and Validate HDL

Your Favorite HDL IDE

Sigasi Studio is a trusted development environment for VHDL and SystemVerilog. Harnessing integrated development, synchronous visualization, and shift-left validation means that HDL specifications are easier than ever to create and hand off without issues.

With Sigasi Studio, you receive instant feedback. We want designers to get alerts about possible errors or issues as early as possible, as complementary help to a classic linter; we want you to shift further left by getting code checks even if you’ve made syntax errors. If you’re still using a regular editor to create your HDL specifications, our IDE will be a pleasant surprise, verifying your code upfront, as you type it.

Once you’ve downloaded Sigasi Studio, you’ll need a license to enjoy our fabulous features. We offer two options to choose from—XL and XPRT licenses. Both offer world-class code creation and project navigation.

Our XPRT license additionally gives you various views, generated from your code, to help have control over your design. Diffs in revision control show what has been changed in the code and the graphics adapt automatically, a vast improvement over working with binary file formats!
