NAME¶

applybddnodeterm - applies an operator on two bdd nodes.

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 ∗applybddnodeterm( BddSystem, Oper, Index, BddNode )
  bddsystem ∗BddSystem;
  long       Oper;
  bddindex   Index;
  bddnode   ∗BddNode;

PARAMETERS¶

BddSystem

The bdd system.

Oper

The binary operator.

Index

The index of the terminal bdd node.

BddNode

The bdd node.

DESCRIPTION¶

applybddnodeterm computes the boolean function BddNode Oper and the terminal node corresponding to Index in the bdd system BddSystem. The Index parameter can take only the two following values BDD_INDEX_ONE and BDD_INDEX_ZERO. If a null pointer is given, the default bdd system is used.

RETURN VALUE¶

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

ERRORS¶

"bad operator xxx error !"

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 );
   BddNode = applybddnodeterm( (bddsystem ∗)0,
                               ABL_XOR, BDD_INDEX_ONE,
                               searchbddcircuitin( (bddcircuit ∗)0, "i0" ) );
   Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );
   /* displays (not i0) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
