Sigasi® Visual HDL™

Create, Integrate, and Validate HDL - Available End of June 2024

Choose the tier that’s right for you

Introducing Sigasi Visual HDL 2024.1! Available from the marketplace during DAC61 (end of June 2024). Already available for pre-order through our Sales Team. Read the full press release here.

Sigasi will offer our Visual HDL 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.

You’ll be able to try out the features offered in our commercial editions through our easy-to-use Community Edition. Once we’ve launched in June, simply start the SVH™ extension in VS Code and start playing! (Note that Community Edition requires actived talkback, see below.)

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.
