constraintCct - restricts all the outputs within a circuit with a BDD constraint
#include logmmm.h"
void constraintCct(pC,pBdd)
pCircuit pC;
pNode pBdd;
constraintCct() restricts the boolean space to the sub-space corresponding to the on-set of pBdd. This function can be called when a primary input is stuck at 0 or 1.
initializeBdd(SMALL_BDD);
pC = initializeCct("circuit 1",10,10);
addInputCct(pC,"a");
addInputCct(pC,"b");
addOutputCct(pC,"s",applyBinBdd(XOR,
createNodeTermBdd(searchInputCct(pC,"a")),
createNodeTermBdd(searchInputCct(pC,"b"))));
/* b is stuck at 1 */
