"Sigasi drastically improved my productivity and code quality. This allowed my company to rapidly offer top-notch designs to my customers which often ask for late changes. This advantage is crucial when working in mission and safety critical applications."

Marco Ruiz

"As a consultant who sometimes comes in mid-project, it makes navigating an unfamiliar codebase so much easier. Linting, completion, and refactoring make it quick and easy to improve/maintain code quality."

"Easy to use, fast and responsive interface and it makes mundane parts of vhdl like instantiations much more bearable and less error prone."

"Revolutionized my life 10 years ago. Still use it every day."
