Note the operator precedence; the "INV" operator is associated with the term to its left, and the AND, OR, XOR, etc. follow standard logic equation precedence rules. Don't forget the semicolon after the assign statement! So going back to our example, assign led = switch[0] & ~switch[...
If a=4'b1010 and b=4'b10x0 Operators Precedence The order of the table tells what operation is made first, the first ones has the highest priority. The () can be used to override default. // conditional operator ?:, this example is an expression that implements min(a, 10)wireout;a...
