Synopsys

#include bdd101.h"
bddnode *setbddrefext( BddNode )
bddnode *BddNode;

Parameters

BddNode
The bdd node.

Description

setbddrefext increments the number of external reference of the bdd node BddNode and decrements its number of internal reference.

Return Value

setbddrefext returns the BddNode pointer.

Errors

negative reference, index xxx error !" The BddNode must have a postive number of internal reference.

Example

#include bdd101.h"
bddsystem *BddSystem;
bddcircuit *BddCircuit;

bddnode
*BddNode; chain_list *Expr; BddSystem = createbddsystem( 100, 1000, 100, 50000 ); BddCircuit = createbddcircuit( hello_world", 10, 10, BddSystem ); BddNode = addbddcircuitin( (bddcircuit *)0, i0", 0, BDD_IN_MODE_FIRST ); BddNode = addbddnode( (bddsystem *)0, BddNode->INDEX, BddNode->LOW, BddNode->HIGH ); Expr = convertbddcircuitabl( (bddcircuit *)0, BddNode ); incbddrefint( BddNode ); setbddrefext( BddNode ); /* displays Node VAR: 0 INDEX: 2 MARK: 0 REF_EXT: 1 REF_INT: 0 */ viewbddnode( (bddsystem *)0, BddNode ); /* displays (not i0) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 );
