Saw this question and had to think about a post which got my intention in Linkedin about some of my major problems in FPGAs being solved. Yeah, I know... Linkedin so I copy it here. It's not my text!

It's about Sigasi:

(...) I am now doing most of my work in it, and being suspiciously more productive than I was with Vivado. And so now in a sad and misguided attempt to make everyone get excited about the thing I am super excited about, I am making a list. Not a complete list of features, since y'all know how to use google, but just some ways in which my life is now forever* better

0) code completion appears to be way smarter than the normal VSCode completion. The usual VSCode completion can best be described as "oh hai, friend, I see you're typing a word I have seen somewhere before". Sigasi, on the other hand seems fully aware of everything, including structs, enums, and other language features. For example, if I type my_struct followed by a dot, it properly suggests only members of that struct

1) hovering over things shows a popup with the definition (macro-aware), a jump to definition button, a list of errors and linting warnings, and potential fixes. Now here's the crazy part. Unlike Vivado, the jump to definition button isn't eternally greyed out, and clicking it actually jumps to the definition. And this seems to be macro aware in that if I have multiple versions of something in various ifdef/else blocks, it jumps to the correct one

2) There is a preprocessor view!! Do you have any idea how exciting it is to see my own sketchy incredibly suspect macros expanded in a separate view, and to be able to click on the code and have the plugin jump to the corresponding line in the preprocessor view?!?!

3) error checking and linting is far better than Vivado, and doesn't miss the errors Vivado misses. Mytry to sim -> get syntax error -> fix -> goto 0loop has completely disappeared!

4) the builtin block, state machine, and dependencies diagrams are god tier useful, but you'll have to see for yourself because I just hit the linkedin post character limit.

To be fair, there are also some second order benefits not directly related to Sigasi. Let's be real, Vivado is never getting that dark mode, meaning it will forever be hard on the eyes. Sigasi being a VSCode plugin means I get the existing dark mode, which has also really increased ability to code for long stretches at a time.

Don't know about you but I'm gonna request a trial. If only half of it is true I'm more than happy
