Name
The Square Root block returns the square root and optional remainder of unsigned
integer input data with the equation:
The Square Root block supports sequential mode (when the number of pipeline
stages> 0) or combinational mode (when the number of pipeline stages = 0).
Assume the radical d is an unsigned integer, and that q and the remainder are always
unsigned integers.

Direction
Specify the number of bits of the unsigned input signal.
Specify the number of pipeline stages. The computation is sequential
when the pipeline is greater than 1 or combinational when the number
of pipeline stages is zero. The clock enable and asynchronous clear
ports are available only if the number of pipeline stages is greater than
or equal to 1.
Turn on to use the clock enable input (ena).
