NAME¶
polarablexpr - moves inverters to the atomic level.
ORIGIN¶
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at
LIP6 laboratory of Université Pierre et Marie CURIE, in Paris,
France.

SYNOPSYS¶
#include "abl101.h"
chain_list ∗polarablexpr( Expr, Polar )
chain_list ∗Expr;
int Polar;
PARAMETERS¶
- Expr
- Expression to modify.
- Polar
- Expression polarity.
DESCRIPTION¶
polarablexpr modifies
Expr by moving down the inverters to the
atomic level.
polarablexpr applies the Morgan's laws. If
Polar
is equal to ABL_POLAR_NEGATIVE the function returns the modified expression
after having complemented it. The expression pointer
Expr MUSTN'T be
used after the call to this function.
RETURN VALUE¶
polarablexpr returns the modified expression.
EXAMPLE¶
#include "abl101.h"
chain_list ∗Expr1;
chain_list ∗Expr2;
Expr1 = createabloper( ABL_NOT );
Expr2 = createabloper( ABL_NOT );
addablhexpr( Expr1, createablatom( "a" ) );
addablhexpr( Expr2, Expr1 );
Expr1 = polarablexpr( Expr2, ABL_POLAR_POSITIVE );
/* displays a */
viewablexpr( Expr1, ABL_VIEW_VHDL );
