VCS error due to defining default net type as none for primitives about skywater-pdk HOT 3 OPEN

Is it safe to comment out `default_nettype none and why does this help? I'm guessing it's a VCS quirk. I'm also not sure why SET is flagged but other ports/identifiers are not. SET seems to be declared as one would expect, but maybe this is a VCS bug or some other issue to do with SET often being a keyword in various implementations...?

It works because the default net type in verilog is wire. So if the default net type doesn't change any net with no definition would considered as a wire.
The 2 code below would be equivalent:

    input  SET  ;

    input  wire SET  ;

but they are not in the case of default net type none

Ah right, thanks @M0stafaRady! So I assume the reason it isn't flagged on the line above it (output Q) is because later Q is declared as a reg. Cool, thanks for the feedback.
