Create & edit RTL faster in Sigasi Visual HDL

Sigasi is much more than an editor but it wouldn’t be Sigasi without syntax checking, formatting, auto-completion, or content assist. Sigasi has a built-in incremental real-time compiler that follows the reference manuals of Verilog, SystemVerilog, and VHDL. The Sigasi editor is packed with features for the FPGA or ASIC design engineer writing code or using AI generated code.

• Hover to immediately get the necessary context from any identifier or type
• Quick fixes fix linting violations with 1 simple click
• Autocomplete ensures you don’t need to remember syntax and names and saves you a lot of typing work
• Signature helper keeps signatures in sight, eliminating needless back and forths between two files
• Sticky scroll keeps all parent elements in sight, even if they’re hundreds of lines higher up
• Smart indentation ensures the most likely indentation is applied after pressing enter
• Preprocessor view offers insights into how your code is handled by the preprocessor
• Folding lets you hide unnecessary details
• Stuttering enables fast typing of common symbol combinations
• Generic editor features help you with day-to-day coding, such as auto-closing brackets

In this 5 minutes demo you’ll get the basics. Feel free to get in touch with us for more info or watch our other shorts serie.

Built for engineers and agents

AI can produce lines of code. Sigasi ensures those lines make sense in context. With real-time semantic awareness in the editor, engineers get immediate feedback on correctness, scope, and intent. Whether code is written by a human or generated by AI, Sigasi keeps the editing experience grounded in deterministic validation.
