Module cdc_fifo_2phase
A clock domain crossing FIFO, using 2-phase hand shakes.
This FIFO has its push and pop ports in two separate clock domains. Its size can only be powers of two, which is why its depth is given as 2**LOG_DEPTH. LOG_DEPTH must be at least 1.
CONSTRAINT: See the constraints for cdc_2phase. An additional maximum
delay path needs to be specified from fifo_data_q to dst_data_o.
Parameters
T
The data type of the payload transported by the FIFO.
LOG_DEPTH
The FIFO's depth given as 2**LOG_DEPTH.
PTR_WIDTH
PTR_FULL
