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);
