void beh_makbdd (fig_pnt) struct befig *fig_pnt;
pointer of the BEFIG structure
beh_makbdd() reads a whole behavioral description (a BEFIG) and creates a BDD for each expression present in the description. For simple signals (simple outputs - BEOUT, simple iternal signals - BEAUX, simple internal delayed signals - BEDLY), one BDD is created which corresponds to the expression that drives the signal. The BDD is stored into a specific field in the corresponding structure (NODE). For signals that have multiple expressions (registers, internal busses, bussed ports), one BDD 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.
