Name

simplifNotExpr - makes simplifications on an expression including inverters

Synopsys

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

Parameter

expr
expression to simplify

Description

simplifNotExpr() makes simplifications by applying the following rule :

(not (not a)) --> a

Example

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

/* let's suppose that expr1 = (OR (NOT (NOT a)) (NOT (NOT (NOT b)))) */

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