Name

upVarBdd - brings up an index in a BDD

Synopsys

#include logmmm.h"
pNode upVarBdd(pBdd,oldIndex,newIndex)
pNode pBdd;
short oldIndex,newIndex;

Parameters

pBdd
BDD in wich index is came up
oldIndex
index to come up
newIndex
new index

Description

upVarBdd() constructs a graph obtained by bringing up oldIndex to newIndex. This function is called by the BDDs reordering function.

Example

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

initializeBdd(SMALL_BDD);
nodeA = createNodeTermBdd(3) ;
nodeB = createNodeTermBdd(3) ;
res = applyBinBdd(OR,nodeA,nodeB); /* res = (OR a b) res = upVarBdd(res,2,4);
displayBdd(res,1);

/* it will display

@res
INDEX 4 LOW = @nodeB HIGH = ONE @nodeB INDEX 3 LOW = ZERO HIGH = ONE */

destroyBdd(1) ;

Error

upVarBdd : error - newIndex <= oldIndex" The new index must be higher than the old index.
