Supported: •Both operands are constants, with the second operand being non-negative. •If the first operand is a 2, then the second operand can be a variable. •Vivado synthesis does not support the real data type. Any combination of operands that results in a real type causes an error. •The values X (unknown) and Z (high impedance) are not allowed. |
