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