NAME

       createbddsystem - creates a bdd system.

SYNOPSYS

       #include "bdd101.h"
       bddsystem ∗createbddsystem( ModelVar, ModelOper, MaxVar, MaxNode  )
         long   ModelVar;
         long   ModelOper;
         long   MaxVar;
         long   MaxNode;

PARAMETERS

       ModelVar            Initial size of the hash table uses for a variable.

       ModelOper           Size of the hash table uses as a cache.

       MaxVar              Initial maximum number of variables.

       MaxNode             Maximum nodes allowed.

DESCRIPTION

       createbddsystem creates and initializes a bdd system.

RETURN VALUE

       createbddsystem returns a pointer to the bdd system created.

ERRORS

       "system model variable xxx error !"
              The ModelVar parameter must be a positive value.
       "system model oper xxx error !"
              The ModelOper parameter must be a positive value.
       "variable xxx out of range error !"
              The MaxVar parameter must be less than BDD_MAX_VAR.

EXAMPLE

       #include "bdd101.h"
          bddsystem ∗BddSystem;
          BddSystem = createbddsystem( 100, 1000, 100, 50000 );
          ...
          destroybddsystem( BddSystem );
