POLARABLEXPR(3) 						   ABL FUNCTIONS						   POLARABLEXPR(3)

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 Universite 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 );
