NAME¶
polardupablexpr - duplicates an expression and moves down the inverters.
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 ∗polardupablexpr( Expr, Polar )
chain_list ∗Expr;
int Polar;
PARAMETERS¶
- Expr
- Expression to modify.
- Polar
- Expression polarity.
DESCRIPTION¶
polardupablexpr modifies
Expr by moving down the inverters to the
atomic level.
polardupablexpr applies the Morgan's laws. If
Polar is equal to ABL_POLAR_NEGATIVE the function returns the modified
expression after having complemented it.
RETURN VALUE¶
polardupablexpr 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 = polardupablexpr( Expr2, ABL_POLAR_POSITIVE );
/* displays a */
viewablexpr( Expr1, ABL_VIEW_VHDL );
