Name

delbddnode - deletes an unused bdd node.

Origin

This software belongs to the ALLIANCE CAD system from the CAO-VLSI team at ASIM/LIP6/UPMC laboratory.

Synopsys

#include bdd101.h"
void delbddnode( BddSystem, BddNode )
bddsystem *BddSystem;
bddnode *BddNode;

Parameters

BddSystem
The bdd system.
BddNode
The bdd node.

Description

delbddnode tries to delete the bdd node BddNode and its children, if they have not external reference, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The use of this function is not recommended because, it takes time. It is better to call the decb_ddrefext function, and do a garbage collection with the garbagebddsystem function.

Return Value

delbddnode returns nothing.

Example

#include bdd101.h"
bddsystem *BddSystem;
bddcircuit *BddCircuit;

bddnode
*BddNode; chain_list *Expr; BddSystem = createbddsystem( 100, 1000, 100, 50000 ); BddCircuit = createbddcircuit( hello_world", 10, 10, BddSystem ); BddNode = addbddcircuitin( (bddcircuit *)0, i0", 0, BDD_IN_MODE_FIRST ); BddNode = addbddnode( (bddsystem *)0, BddNode->INDEX, BddNode->LOW, BddNode->HIGH ); Expr = convertbddcircuitabl( (bddcircuit *)0, BddNode ); delbddnode( (bddsystem *)0, decbddrefext( BddNode ) ); /* displays (not i0) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 );
