[sv-bc] RE: initialization of unpacked union in declaration

Maybe, but the LRM does not say so. It is silent.

I would guess that it would be an aggregate expression of the type of the first member.

module bar();

union {
  bit a;
  string b;
} c = '{1'b1};

endmodule

Hi,
I never got any response to this.
I know some people are on vacation, but does no one have anything to say?
Thanks,
Shalom

Hi,
The LRM says in 7.3,
"If no initial value is specified in the declaration of a variable of an unpacked union type, then the variable shall be initialized to the default initial value for variables of the type of the first member in declaration order of the union type."
Question: how *does* one specify an initial value of an unpacked union variable in its declaration?
Thanks,
Shalom
