Name

gcNodeCct - does a garbage collection

Synopsys

#include logmmm.h"
void gcNodeCct(pC)
pCircuit pC;

Parameter

pC
circuit on which the nodes are saved

Description

gcNodeCct() does a garbarge collection by removing the nodes that aren't pointed in pC.

Example

#include mutnnn.h
/* mbk utilities */ #include logmmm.h" pCircuit pC; chain_list *expr;

initializeBdd(SMALL_BDD);
pC = initializeCct("circuit 1",10,10);

addInputCct(pC,"a");
addInputCct(pC,"b");

/* let's suppose that expr = (OR a b) */

addOuputCct(pC,"s1",one);
addOuputCct(pC,"s2",ablToBddCct(pC,expr));

printf("number of nodes of the BDDs system = %d",numberNodeAllBdd()); gcNodeCct(pC,1)
printf("After GC : number of nodes of the BDDs system = %d",numberNodeAllBdd());

/* it will display
number of nodes of the BDDs system = 3 After GC : number of nodes of the BDDs system = 2 */ destroyCct(pC) ;
destroyBdd(1) ;
