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.

Latest News
Sigasi, your first line of defense
A recent GPTZero investigation should make every engineer pause. They scanned 4,841 accepted NeurIPS 2025 papers and reported 100+ confirmed hallucinated citations spread across 50+ papers; issues that slipped past “3+ reviewers” per paper.
18th Birthday
Exactly 18 years ago today, our founders—Hendrik Eeckhaut, PhD in Computer Science Engineering, and Philippe Faes, freshly graduated at the time—launched Sigasi with a single mission: “to make chip design easier and faster”.
Done doesn't mean "correct"
If you’re managing chip projects, the hardest part isn’t writing/generating more RTL; it’s predicting verification + debug. This isn’t an “FPGA problem” or an “ASIC problem.” It’s a verification predictability problem.
The 7 Advantages for (E)CAD Managers
The success of an (E)CAD Manager is measured on predictable delivery and risk reduction. Tooling decisions directly impact productivity, code quality, onboarding speed, and ultimately time-to-market. That’s exactly where Sigasi Visual HDL makes the difference.
Verification is eating the schedule
The 2024 Wilson Research Group Functional Verification Trend Reports point to a harsh reality: design complexity is rising faster than verification capacity, and the industry is paying for it in escapes, respins, and delays.
12,000 Downloads and Counting
It took us more than one year to get to 10,000 downloads. In less than 2 months, 2,000 more downloads were done. Our mission to empower design and verification engineers to save time and costs for their team/company pays off.
Seeing is Believing. Feeling is the Truth.
Request a free trial and discover how easy it is to improve RTL quality, reduce debugging time and save money. As an (E)CAD Manager or Teamlead leading a team of design and/or verification engineers you can also request a floating license trial for multiple users.
