DP_NUL - Zero Detect
#include <fpgen.h>
void DP_NUL(
char *InstName, /* Instance name */
long Width , /* Number of bits */
long Slice , /* Index of the bottom slice */
char *BusI0 , /* IN Operand input DATA */ char *SigNul , /* OUT Zero flag output DATA */ EOL);
DP_NUL creates a zero detect operator of Width bits and then instanciates it with the name InstName. The maximal authorized value for Width is the full width of the current data-path, set by the previous call to the function DP_DEFLOFIG. In the layout the leaf cells are placed on the slices numbered from Slice to Slice+Width-1 (the bottom slice of the whole data-path is numbered zero).
Operator wide : drive 4 to 8 --> 24 lambdas. drive 9 to 16 --> 29 lambdas. drive 17 to 32 --> 32 lambdas.
