Welcome to Sigasi Visual HDL (SVH™)!
SVH is an HDL platform, the place where chip designers and verification engineers can shift their hardware design language (HDL) and register transfer language (RTL) projects to the left. (Find out more about what “shifting left” means in our FAQ section!)
Fully integrated within the leading integrated development environment (VS Code ), SVH harnasses the rich marketplace of existing tools like source control management (SCM), central repositories, gremlin tracking, bookmarks, and comment-based TODO lists.
To make life even easier, SVH gives you tiered editions that build on each other in a single extension. One download, many license options.
Each edition uses industry standards to ensure you get the highest quality checks as you create your code, with specific language and standards support.
Create with type-time syntax and semantic checks; guardrails that enforce coding styles, policies, and standards; and instant feedback and warnings for any files associated with a project.
Moreover, Sigasi offers numerous ways to view a project, all updated in real-time (no need to save first) and with cross-probing. Move seamlessly through hierarchy views and graphics that update instantaneously as you make changes in your code.
How does it work?
Download the SVH extension at the VS Code marketplace .
Configure your license, which unlocks your edition and related features. Input the key we provide when you buy a commercial license when prompted. Or you can try out most of SVH’s features by choosing our Community Edition. (Note that Community Edition requires actived Talkback, see below.) Students can use Community Edition to better learn the fundamentals of HDL.
Sigasi users who have a commercial license for our older products can seamlessly transition to SVH, just input your existing license information. Not ready to switch yet? You can find information about Sigasi Studio at our Legacy Section . Or talk to our Sales Team about your options.

Download NowRequires Active Talkback
Talkback automatically collects metadata about how someone uses Sigasi Visual HDL—only telemetry, no design data—and sends this metadata to Sigasi through a secured connection. You can read all the details here.
By enabling Talkback, you help us improve SVH
- Talkback provides us with feature usage. This information helps us determine which features are valuable for you as a user so we can adjust our product roadmap.
- Talkback collects performance statistics that we can relate to the project sizes. Together with our in-house performance tests, this helps us keep the SVH compiler and user interface fast.
- Talkback helps us reduce software errors by collecting incident reports from various use cases.
- Talkback is automatic and less cumbersome than feedback surveys.
