And even with the commercial tools the set of SystemVerilog features supported varies wildly.

They're getting good at the RTL bits these days. always_ff, always_comb, structs, unions, enums all very useful.

Unfortunately the SystemVerilog standard doesn't bother defining which bits are synthesizable..

I think in the long run Verilog will have a more "assembly like" role in most flows. Verilog is absolutely sufficient for that role.

Maybe. I feel someone needs to invent Verilog DWARF first so waveform viewers can annotate actual source.

I think a small standard subset of Verilog + select features from SV would be very useful.

From SV I'd only like immediate assert/assume/restrict/cover, always_comb, and $urandom.

Not concurrent assertions? D: Seriously SVAs are the best.

They are neat, sure. But you can also just write checker FSMs.. probably even easier when generating from other higher level languages.

OTOH none of the formal tools I've encountered will do immediate assertions. Just concurrent.

Yosys can do immediate assertions.

Please stop feeding arguments to ARM people for using Yosys.
