The SV package is very nice. I love it. Just not autocomplete :).
I am not sure what you mean by screenshot what “autocomplete” I mean… But here is an example. if I start typing a variable name, like rsp_ and then hit tab repeatedly, then for each tab a get a different rsp_* variable.
What I do NOT get is this. If I type always_ff and hit tab, then I do not get a template for an always block. I am starting to suspect that the autocomplete might be from the base sublime3 options, not from the sytemverilog package.
I have autocomplete turned off there too, but I cannot kill the darn thing
