Sigasi® Visual HDL™

Create, Integrate, and Validate HDL - Available Now

Choose the tier that’s right for you

Introducing Sigasi Visual HDL 2024.1!

We offer Sigasi Visual HDL (SVH™) in tiered editions that build on each other, each seamlessly elaborating on the last. Each edition uses industry standards to ensure you get the highest quality checks as you create your code, with specific language and standards support within the leading integrated development environment (VS Code) that frictionlessly incorporates tools like source control management (SCM), central repositories, gremlin tracking, bookmarks, and comment-based TODO lists.

Create in an environment that fully embraces the shift-left principle. Get 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.

Try out the features offered in our commercial editions through our easy-to-use Community Edition. Simply start the SVH extension in VS Code and start playing! (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 download it from the VS Code marketplace. 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.

Requires Active Talkback

Requires Active Talkback

Talkback automatically collects metadata about how someone is using SVH (but 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.
