NAME¶

applybddnodeite - computes the IF-THEN-ELSE logical operation.

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. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr

SYNOPSYS¶

#include "bdd101.h"
bddnode ∗applybddnodeite( BddSystem, BddIf, BddThen, BddElse )
  bddnode   ∗BddSystem;
  bddnode   ∗BddIf;
  bddnode   ∗BddThen;
  bddnode   ∗BddElse;

PARAMETERS¶

BddSystem

The bdd system.

BddIf

The IF bdd node.

BddThen

The THEN bdd node.

BddElse

The ELSE bdd node.

DESCRIPTION¶

applybddnodeite computes the following logical function ( BddIf AND BddThen) OR ((NOT BddIf) AND BddElse) in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

RETURN VALUE¶

applybddnodeite returns a pointer to the resulting bdd node with its number of external reference incremented.

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 );
   addbddcircuitin( (bddcircuit ∗)0, "i0", 0, BDD_IN_MODE_FIRST );
   addbddcircuitin( (bddcircuit ∗)0, "i1", 0, BDD_IN_MODE_FIRST );
   addbddcircuitin( (bddcircuit ∗)0, "i2", 0, BDD_IN_MODE_FIRST );
   BddNode = applybddnodeite( (bddsystem ∗)0,
                              searchbddcircuitin( (bddcircuit ∗)0, "i0" ),
                              searchbddcircuitin( (bddcircuit ∗)0, "i1" ),
                              searchbddcircuitin( (bddcircuit ∗)0, "i2" ) );
   Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );
   /* displays ((i0 and i1) or ((not i0) and i2) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
