Greg, > signed'(1'b1) will 0-extend the literal before cloaking it > with signedness I don't think so. See, for example, in 11.7: regS = signed'(4'b1100); // regS = -4 According to you, the RHS becomes 8'sb00001100, which is not -4. If it is first turned to signed, 4'sb1100, then size-extended, it becomes 8'sb11111100, which is indeed -4. 6.24.1 says, "The cast shall return the value that a variable of the casting type would hold after being assigned the expression."
