Synopsys

#include bdd101.h"
bddassoc *addbddassoc( BddSystem )
bddsystem *BddSystem;

Parameters

BddSystem
The bdd system.

Description

addbddassoc creates a new association variables in the bdd system BddSys_tem. If a null pointer is given, the default bdd system is used.

Return Value

addbddassoc returns a pointer to the new variable association.

Errors

no more variable association, error !" There is no variable association number left.

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 ); delbddassoc( (bddsystem *)0, Assoc ); 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 );
