The bnet package

Simple-minded package to read a blif file.




int 
Bnet_BuildNodeBDD(
  DdManager * dd, DD manager
  BnetNode * nd, node of the boolean network
  st_table * hash, symbol table of the boolean network
  int  params, type of DD to be built
  int  nodrop retain the intermediate node DDs until the end
)
Builds the BDD for the function of a node and stores a pointer to it in the dd field of the node itself. The reference count of the BDD is incremented. If params is BNET_LOCAL_DD, then the BDD is built in terms of the local inputs to the node; otherwise, if params is BNET_GLOBAL_DD, the BDD is built in terms of the network primary inputs. To build the global BDD of a node, the BDDs for its local inputs must exist. If that is not the case, Bnet_BuildNodeBDD recursively builds them. Likewise, to create the local BDD for a node, the local inputs must have variables assigned to them. If that is not the case, Bnet_BuildNodeBDD recursively assigns variables to nodes. Bnet_BuildNodeBDD returns 1 in case of success; 0 otherwise.

Side Effects Sets the dd field of the node.

int 
Bnet_DfsVariableOrder(
  DdManager * dd, 
  BnetNetwork * net 
)
Orders the BDD variables by DFS. Returns 1 in case of success; 0 otherwise.

Side Effects Uses the visited flags of the nodes.

void 
Bnet_FreeNetwork(
  BnetNetwork * net 
)
Frees a boolean network created by Bnet_ReadNetwork.

Side Effects None

See Also Bnet_ReadNetwork
void 
Bnet_PrintNetwork(
  BnetNetwork * net boolean network
)
Prints to the standard output a boolean network created by Bnet_ReadNetwork. Uses the blif format; this way, one can verify the equivalence of the input and the output with, say, sis.

Side Effects None

See Also Bnet_ReadNetwork
int 
Bnet_PrintOrder(
  BnetNetwork * net, 
  DdManager * dd 
)
Prints the order of the DD variables of a network. Only primary inputs and present states are printed. Returns 1 if successful; 0 otherwise.

Side Effects None

BnetNetwork * 
Bnet_ReadNetwork(
  FILE * fp, pointer to the blif file
  int  pr verbosity level
)
Reads a boolean network from a blif file. A very restricted subset of blif is supported. Specifically: Caveat emptor: There may be other limitations as well. One should check the syntax of the blif file with some other tool before relying on this parser. Bnet_ReadNetwork returns a pointer to the network if successful; NULL otherwise.

Side Effects None

int 
Bnet_ReadOrder(
  DdManager * dd, 
  char * ordFile, 
  BnetNetwork * net, 
  int  locGlob, 
  int  nodrop 
)
Reads the variable order from a file. Returns 1 if successful; 0 otherwise.

Side Effects The BDDs for the primary inputs and present state variables are built.

int 
Bnet_bddArrayDump(
  DdManager * dd, DD manager
  BnetNetwork * network, network whose BDDs should be dumped
  char * dfile, file name
  DdNode ** outputs, BDDs to be dumped
  char ** onames, names of the BDDs to be dumped
  int  noutputs, number of BDDs to be dumped
  int  dumpFmt 0 -> dot
)
Writes an array of BDDs to a file in dot, blif, DDcal, factored-form, or daVinci format. The BDDs and their names are passed as arguments. The inputs and their names are taken from the network. If "-" is passed as file name, the BDDs are dumped to the standard output. Returns 1 in case of success; 0 otherwise.

Side Effects None

int 
Bnet_bddDump(
  DdManager * dd, DD manager
  BnetNetwork * network, network whose BDDs should be dumped
  char * dfile, file name
  int  dumpFmt, 0 -> dot
  int  reencoded whether variables have been reencoded
)
Writes the network BDDs to a file in dot, blif, or daVinci format. If "-" is passed as file name, the BDDs are dumped to the standard output. Returns 1 in case of success; 0 otherwise.

Side Effects None
