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 );
