Sigasi Visual HDL vs TerosHDL

Sometimes we get the question: Why pay for Sigasi Visual HDL? Adding the claim: TerosHDL does “the same” for free

TL;DR

We wanted to factcheck that claim, did a full investigation and one of our hardware engineers made a comparison feature by feature on the differences between Sigasi Visual HDL and Teros HDL. This comparison was made based on publicly available documentation, Teros HDL version 7.0.3 (3/25/2025), our friends at ChatGPT, Gemini, Claude, Perplexity,… and user feedback. It becomes quickly clear that TerosHDL by Teros Technology does not match the capabilities and features of Sigasi Visual HDL and that the claim “it does the same” is false.
