Synopsys

#include bdd101.h"
chain_list *convertbddmuxabl( BddSystem, NameArray, IndexArray, Equation, BddHigh, BddLow ) bddsystem BddSystem;

char
(*NameArray; bddindex IndexArray; chain_list Equation;
bddnode
BddHigh;
bddnode
BddLow;

Parameters

BddSystem
The bdd system.
NameArray
The array of names.
IndexArray
The array of indexes.
Equation
The multiplexor command.
BddHigh
The first bdd node.
BddLow
The second bdd node.

Description

convertbddmuxabl creates the following abl expression ( BddHigh AND Equa_tion ) OR ( BddLow AND (NOT Equation ) ) in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The NameArray, and IndexArray parameters are used to translate the variable nodes into atomic expressions. The array NameArray is list of names. The array IndexArray does the correspondence between a bdd node index and a slot in the NameArray. If the IndexArray parameter is a null pointer, then the name of the bdd index BDD_INDEX_MIN is assumed to be the first slot of the NameArray, and so on.

Return Value

convertbddmuxabl returns a pointer to the abl expression translated.

Example

#include bdd101.h"
bddsystem *BddSystem;

bddnode
*BddNode1;
bddnode
*BddNode2; chain_list *Expr;
char
*NameArray[ 2 ]; BddSystem = createbddsystem( 100, 1000, 100, 50000 ); BddNode1 = addbddvarlast( BddSystem ); BddNode2 = addbddvarlast( BddSystem ); NameArray[ 0 ] = namealloc( i0 ); NameArray[ 1 ] = namealloc( i1 ); Expr = convertbddmuxabl( BddSystem, NameArray, (bddindex *)0, createablatom( C ), BddNode1, BddNode2 ); /* displays (i0 and C) or (i1 and (not C)) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem *)0 );
