COMPOSEBDDNODE(3) BDD FUNCTIONS COMPOSEBDDNODE(3)NAMEcomposebddnode - substitutes a variable by a bdd in another bdd.ORIGINThis software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in Paris, France. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.frSYNOPSYS#include "bdd101.h" bddnode *composebddnode( BddSystem, BddNode, Variable, BddSubst ) bddsystem *BddSystem; bddnode *BddNode; bddvar Variable; bddnode *BddSubst;PARAMETERSBddSystem The bdd system. BddNode The bdd node. Variable The variable to find. BddSubst The bdd to substitute with.DESCRIPTIONcomposebddnode substitutes all the occurency of the variable Variable in the bdd node BddNode by the bdd node BddSubst, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.RETURN VALUEcomposebddnode returns the resulting bdd node.ERRORS"variable xxx out of range, error !" The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.EXAMPLE#include "bdd101.h" bddsystem *BddSystem; bddcircuit *BddCircuit; bddnode *BddVariable; bddnode *BddNode; bddnode *BddSubst; chain_list *Expr; bddvar Variable; BddSystem = createbddsystem( 100, 1000, 100, 50000 ); BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem ); Expr = createablbinexpr( ABL_AND, createablatom( "i0" ), createablatom( "i1" ) ); BddNode = addbddcircuitabl( BddCircuit, Expr ); freeablexpr( Expr ); Expr = createablbinexpr( ABL_OR, createablatom( "i2" ), createablatom( "i3" ) ); BddSubst = addbddcircuitabl( BddCircuit, Expr ); freeablexpr( Expr ); BddVariable = searchbddcircuitin( (bddcircuit *)0, "i0" ); Variable = getbddvarbyindex( (bddsystem *)0, BddVariable->INDEX ); BddNode = composebddnode( (bddsystem *)0, BddNode, Variable, BddSubst ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays (i1 and (i2 or i3)) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 );SEE ALSObdd(1)BUG REPORTThis tool is under development at the ASIM department of the LIP6 laboratory. We need your feedback to improve documentation and tools.ASIM/LIP6 October 1, 1997 COMPOSEBDDNODE(3)
