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 BddSys_tem. 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->NUM_BER_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 );
