Name

applyBdd - applies an operator to a list of BDD.

Synopsys

#include logmmm.h"
pNode applyBdd(oper,pt)
short oper;
chain_list *pt;

Parameters

oper
operator number to apply (OR,AND,XOR,NAND,NOR,NXOR,NOT)
pt
chain_list of BDD.

Description

applyBdd() applies oper to a list of Bdd. This list can be created by addListBdd() function. This function provides the basic method for creating the representation of a function according to the operators in a boolean expression.

Example

#include mutnnn.h
/* mbk utilities */ #include logmmm.h" pNode nodeA,nodeB,nodeC; pNode res; chain_list *pt;

initializeBdd(SMALL_BDD);
nodeA = createNodeTermBdd(3) ;
nodeB = createNodeTermBdd(3) ;
nodeC = createNodeTermBdd(4) ;
pt = NULL;
pt = addListBdd(pt,nodeA);
pt = addListBdd(pt,nodeB);
pt = addListBdd(pt,nodeC);
res = applyBdd(OR,pt);
displayBdd(res,1);

/* it will display

@res
INDEX = 4 LOW = @inter HIGH = ONE

@inter INDEX = 3 LOW = @nodeA HIGH = ONE @nodeA INDEX = 2 LOW = ZERO HIGH = ONE */

destroyBdd(1) ;

Errors

applyBdd : error - unknown operator"
the operator number must be in (OR,AND,XOR,NAND,NOR,NXOR,NOT) applyBdd : error - chained list is empty" chained list pointer pt = NULL.
applyBdd : error - bad operator"
The number of arguments is 1 and the operator is distinct from NOT. chained list pointer pt = NULL.
