NAME¶
setbddrefext - increments the external reference, and decrements the internal
reference of a
bdd node.
ORIGIN¶
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at
LIP6 laboratory of Université Pierre et Marie CURIE, in Paris,
France.

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 );
