NAME¶
implybddnode - computes a bdd that implies a conjonction of two bdd nodes.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.Web : http://asim.lip6.fr/recherche/alliance/
E-mail : alliance-users@asim.lip6.fr
SYNOPSYS¶
#include "bdd101.h" bddnode ∗implybddnode( BddSystem, BddNode1, BddNode2 ) bddsystem ∗BddSystem; bddnode ∗BddNode1; bddnode ∗BddNode2;
PARAMETERS¶
- BddSystem
- The bdd system.
- BddNode1
- The first bdd node.
- BddNode2
- The second bdd node.
DESCRIPTION¶
implybddnode tests if the intersection of BddNode1 and not BddNode2, exists, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.RETURN VALUE¶
implybddnode returns the bdd node zero if there is no intersection, and a computed bdd node otherwise.EXAMPLE¶
#include "bdd101.h" bddsystem ∗BddSystem; bddcircuit ∗BddCircuit; bddnode ∗BddNode1; bddnode ∗BddNode2; bddnode ∗BddImply; chain_list ∗Expr; BddSystem = createbddsystem( 100, 1000, 100, 50000 ); BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem ); Expr = createablbinexpr( ABL_OR, createablatom( "i0" ), createablatom( "i1" ) ); BddNode1 = addbddcircuitabl( BddCircuit, Expr ); freeablexpr( Expr ); Expr = createablbinexpr( ABL_AND, createablatom( "i0" ), createablatom( "i1" ) ); BddNode1 = addbddcircuitabl( BddCircuit, Expr ); freeablexpr( Expr ); BddImply = implybddnode( (bddsystem ∗)0, BddNode1, BddNode2 ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays (i0 and (not i1)) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem ∗)0 ); destroybddcircuit( (bddcircuit ∗)0 );
