convertbddmuxabl.3alc man page

convertbddmuxabl — converts two bdd nodes to an abl multiplexor expression.

Synopsis

#include "bdd101.h"
chain_list *convertbddmuxabl( BddSystem, NameArray, IndexArray, Equation, BddHigh, BddLow )
  bddsystem  ΒddSystem;
  char      (*NameArray;
  bddindex   ΙndexArray;
  chain_list Εquation;
  bddnode    ΒddHigh;
  bddnode    ΒddLow;

Parameters

BddSystem

The bdd system.

NameArray

The array of names.

IndexArray

The array of indexes.

Equation

The multiplexor command.

BddHigh

The first bdd node.

BddLow

The second bdd node.

Description

convertbddmuxabl creates the following abl expression ( BddHigh AND Equation ) OR ( BddLow AND (NOT Equation ) ) in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The NameArray, and IndexArray parameters are used to translate the variable nodes into atomic expressions. The array NameArray is list of names. The array IndexArray does the correspondence between a bdd node  index and a slot in the NameArray. If the IndexArray parameter is a null pointer, then the name of the bdd index BDD_INDEX_MIN is assumed to be the first slot of the NameArray, and so on.

Return Value

convertbddmuxabl returns a pointer to the abl expression translated.

Example

#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddnode    ∗BddNode1;
   bddnode    ∗BddNode2;
   chain_list ∗Expr;
   char       ∗NameArray[ 2 ];
   BddSystem = createbddsystem( 100, 1000, 100, 50000 );
   BddNode1  = addbddvarlast( BddSystem );
   BddNode2  = addbddvarlast( BddSystem );
   NameArray[ 0 ] = namealloc( "i0" );
   NameArray[ 1 ] = namealloc( "i1" );
   Expr = convertbddmuxabl( BddSystem, NameArray, (bddindex ∗)0,
                            createablatom( "C" ),  BddNode1, BddNode2 );
   /* displays (i0 and C) or (i1 and (not C)) */
   viewablexpr( Expr, ABL_VIEW_VHDL );
   freeablexpr( Expr );
   destroybddsystem( (bddsystem ∗)0 );
