NAME
polarablexpr - moves inverters to the atomic level.man2html: unable to open or read file man1/alc_origin.1
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 );
