NAME

addbddcircuitabl - converts an abl expression to a bdd node.

See the file man1/alc_origin.1.

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 );
