Sigasi Visual HDL (SVH) transforms VS Code into a powerful VHDL/Verilog/SV platform for chip designers providing deep design insights and a streamlined workflow. We made our tool for one purpose: build better chips, faster. You catch errors and bugs early in the design cycle which avoids costly delays in the later stages. Visual HDL is an essential tool for advanced chip designers.

Discover Sigasi Visual HDL

The fastest way to a flawless design

Real-time feedback

Gain instant feedback in real-time as you type—no waiting for simulation or synthesis steps. Context-aware insights and actionable suggestions help you quickly spot, investigate, and correct errors to avoid bugs in your design.

Design visualization

See a real-time graphical interactive representation of your design while you type, which allows you to understand even the most complex designs with ease. It empowers visual thinking and smooth navigation between your code and the visual overviews, including block and state machine diagrams.

Verification acceleration

Enjoy the benefits of our actionable real-time feedback and visualization fully applied to your verification code, with built-in support for all industry-standard verification frameworks like UVM, OSVVM, UVVM, VUnit, and Cocotb.

Toolchain leverage

Get the most out of your setup.Your existing tools and workflows, from EDA toolchains to version control systems and CI solutions are seamlessly integrated with industry-standard documentation and reporting tools in our platform.

Functional Safety standards facilitation

Receive warnings and tips that guide you to follow industry or custom in-house rules, removing the hassle of meeting even the most demanding requirements. Sigasi Visual HDL supports compliance with rigorous safety standards like DO-254, ISO 26262, and STARC.

"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

Ectek SRL

"Provides software-development-like IDE capabilities that work well and greatly increase my productivity. Haven’t found another tool anywhere close to the capability. I also appreciate your connection and responsiveness to customers."

"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."
