Name

ablToBddCct - converts an ABL into a BDD within a circuit

Synopsys

#include logmmm.h"
pNode ablToBddCct(pC,expr)
pCircuit pC;
chain_list *expr;

Parameters

pC
Circuit in which is made the conversion
expr
expression to convert

Description

ablToBddCct() constructs the graph that is computed from expr. This function provides the basic method for constructing easily the BDDs. The applyBdd() function is called recursively by going through the ABL.

Example

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

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

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

/* let's suppose that expr = (OR (AND (NOT a) b) a) */

res = ablToBddCct(pC,expr);
displayBdd(res,1);

/* it will display

@res
INDEX = 3 LOW = @nodeA HIGH = ONE
@nodeA
INDEX = 2 LOW = ZERO HIGH = ONE */ destroyCct(pC) ; destroyBdd(1) ;
