addbddcircuitabl.3alc - Man Page

converts an abl expression to a bdd node.

Synopsis

#include "bdd101.h"
bddnode ∗addbddcircuitabl( BddCircuit, Expr )
  bddcircuit ∗BddCircuit;
  chain_list ∗Expr;

Parameters

BddCircuit

The bdd circuit.

Expr

The expression to convert.

Description

addbddcircuitabl converts the abl expression Expr to a bdd node. The BddCircuit is used to translate the atomic expressions into variable nodes. If a null pointer is given, the default bdd circuit is used. If an atomic expression doesn't appear in the BddCircuit  input names hash table or output names hash table, then addbddcircuitabl adds a new input by calling the function  addbddcircuitin with the BDD_IN_MODE_LAST mode.

Return Value

addbddcircuitabl returns a pointer to the bdd node translated.

Errors

"bad operator xxx error !"

The Expr parameter must be a well defined abl expression.

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 );
   Expr = createablbinexpr( ABL_AND, 
                            createablatom( "i0" ),
                            createablatom( "i1" ) );
   BddNode = addbddcircuitabl( BddCircuit, Expr );
   freeablexpr( Expr );
   Expr = convertbddcircuitabl( BddCircuit, BddNode );
   /* displays (i0 and i1) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem ∗)0 );
   destroybddcircuit( (bddcircuit ∗)0 );
