applybddnodeite.3alc - Man Page
computes the IF-THEN-ELSE logical operation.
Synopsis
#include "bdd101.h" bddnode ∗applybddnodeite( BddSystem, BddIf, BddThen, BddElse ) bddnode ∗BddSystem; bddnode ∗BddIf; bddnode ∗BddThen; bddnode ∗BddElse;
Parameters
- BddSystem
The bdd system.
- BddIf
The IF bdd node.
- BddThen
The THEN bdd node.
- BddElse
The ELSE bdd node.
Description
applybddnodeite computes the following logical function (BddIf AND BddThen) OR ((NOT BddIf) AND BddElse) in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.
Return Value
applybddnodeite returns a pointer to the resulting bdd node with its number of external reference incremented.
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 ); addbddcircuitin( (bddcircuit ∗)0, "i0", 0, BDD_IN_MODE_FIRST ); addbddcircuitin( (bddcircuit ∗)0, "i1", 0, BDD_IN_MODE_FIRST ); addbddcircuitin( (bddcircuit ∗)0, "i2", 0, BDD_IN_MODE_FIRST ); BddNode = applybddnodeite( (bddsystem ∗)0, searchbddcircuitin( (bddcircuit ∗)0, "i0" ), searchbddcircuitin( (bddcircuit ∗)0, "i1" ), searchbddcircuitin( (bddcircuit ∗)0, "i2" ) ); Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode ); /* displays ((i0 and i1) or ((not i0) and i2) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem ∗)0 ); destroybddcircuit( (bddcircuit ∗)0 );
