NAME

beh_makgex - create a GEX for each expression in a description

SYNOPSYS

void beh_makgex (fig_pnt)
struct befig *fig_pnt;

PARAMETERS

fig_pnt
pointer of the BEFIG structure

DESCRIPTION

beh_makgex() reads a whole behavioral description (a BEFIG) and creates a GEX for each expression present in the description. A GEX is a structure able to represents binary expressions. It has almost the same organization as an ABL but, like a BDD, uses an index to represent variables. For simple signals (simple outputs - BEOUT, simple iternal signals - BEAUX, simple internal delayed signals - BEDLY), one GEX is created which corresponds to the expression that drives the signal. The GEX is stored into a specific field in the corresponding structure (NODE). For signals that have multiple expressions (registers, internal busses, bussed ports), one GEX is created for each expression and stored in the corresponding field of the structure (CNDNODE for conditions or VALNODE for the value).

fig_pnt represents the pointer of the description.

EXAMPLE

#include <beh109.h>
struct befig *befig_pnt;
beh_makgex (befig_pnt);
