NAME
delbddnodeassoc - deletes a bdd node in a variable association.man2html: unable to open or read file man1/alc_origin.1
SYNOPSYS
#include "bdd101.h" int delbddnodeassoc( BddSystem, BddAssoc, Variable ) bddsystem *BddSystem; bddassoc *BddAssoc; bddvar Variable;
PARAMETERS
- BddSystem
- The bdd system.
- BddAssoc
- The variable association.
- Variable
- The variable number.
DESCRIPTION
delbddnodeassoc deletes the bdd node associated to the variable number Variable, in the variable association BddAssoc, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The number of external reference of the associated bdd node is incremented.RETURN VALUE
delbddnodeassoc returns 1 if the variable is found, 0 otherwise.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 *BddNode; bddnode *BddSubst; bddnode *BddVariable; bddassoc *Assoc; 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 ); Assoc = addbddassoc( (bddsystem *)0 ); addbddnodeassoc( (bddsystem *)0, Assoc, Variable, BddSubst ); BddNode = substbddnodeassoc( (bddsystem *)0, BddSubst, Assoc ); delbddnodeassoc( (bddsystem *)0, Assoc, Variable ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays ((i3 or i2) and i1) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddassoc( (bddsystem *)0 ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 );
