Name

devXor2Expr - converts XOR 2 to OR-AND

Synopsys

#include logmmm.h"
chain_list *devXor2Expr(expr)
chain_list *expr;

Parameter

expr
XOR expression

Description

devXor2Expr() removes XOR 2 at the first level by applying the rule :

(XOR a b) --> (OR (AND a (NOT b)) (AND (NOT a) b))

Example

#include mutnnn.h
/* mbk utilities */ #include logmmm.h" chain_list *expr1,*expr2;

/* let's suppose that expr1 = (XOR a b) */

expr2 = devXor2Expr(expr1);
displayExpr(expr2);
/* it will display
(OR (AND a (NOT b)) (AND (NOT a) b)) */
freeExpr(expr1);
freeExpr(expr2);
