This leads to a final solution of "assign F = ~(A ^ B);" 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...
Relational operators have a lower precedence than arithmetic operators and all relational operators have the same precedence. OperatorDescription a < b a less than b a > b a greater than b a <= b a less than or equal to b a >= b a greater than or equal to b module des; reg [7:...
In any instance where a reasonable human would need to expend thought or refer to an operator precedence chart, use parentheses instead to make the order of operations unambiguous. Ternary Expressions Ternary expressions nested in the true condition of another ternary expression must be enclosed in ...
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;assignout = a >10?10: a;// if...
list, whereas C uses { }. Early versions of the SystemVerilog draft standard used simple{ } braces to delimit value lists, like C. The final version of the IEEE SystemVerilog changed the delimiter to ’{ } to distinguish the list of values from Verilog’s { } concatenation operator. ...
