^ in Verilog?

Question

What is the ^ symbol used for in Verilog?

Answer 1

This is 'XOR'. It may be either unary or binary operator.

a ^ b - is a XOR b

^a - is a bit-wise XOR, the result is scalar single bit value that is XOR of all bits of the vector a.

Answer 2

It is a reduction XOR operator. It performs bit-wise operation on an operand. Operand is a multibit vector and the output is a single bit after this operation is performed. It performs bit-wise XOR reduction on all bits of the input vector and returns a single bit.

Answer 3

it's xor logic
