Function Documentation

add_net_to_hash()

static int add_net_to_hash ( t_hash **  nhash, const char *  net_name, int *  ncount  )

static

Adds net to hashtable of nets.

If the net is "open", then this is a keyword so do not add it. If the net already exists, increase the count on that net

alloc_pb_route()

static t_pb_routes alloc_pb_route ( t_pb_graph_node *  pb_graph_node )

static

load_atom_index_for_pb_pin()

static void load_atom_index_for_pb_pin ( t_pb_routes &  pb_route, int  ipin  )

static

load_atom_pin_mapping()

static void load_atom_pin_mapping ( const ClusteredNetlist &  clb_nlist )

static

Walk through the atom netlist looking up and storing the t_pb_graph_pin associated with each connected AtomPinId.

load_external_nets_and_cb()

static void load_external_nets_and_cb ( ClusteredNetlist &  clb_nlist )

static

This function updates the nets list and the connections between that list and the complex block.

load_internal_to_block_net_nums()

static void load_internal_to_block_net_nums ( const t_logical_block_type_ptr  type, t_pb_routes &  pb_route  )

static

mark_constant_generators()

static void mark_constant_generators ( const ClusteredNetlist &  clb_nlist, int  verbosity  )

static

mark_constant_generators_rec()

static size_t mark_constant_generators_rec ( const t_pb *  pb, const t_pb_routes &  pb_route, int  verbosity  )

static

processAttrsParams()

template<typename T >

void processAttrsParams	(	pugi::xml_node	Parent,
		const char *	child_name,
		T &	atom_net_range,
		const pugiutil::loc_data &	loc_data
	)

This processes a set of key-value pairs in the XML.

e.g. block attributes or parameters, which must be of the form <attributes><attribute name="attrName">attrValue</attribute> ... </attributes>

processComplexBlock()

static void processComplexBlock ( pugi::xml_node  clb_block, const ClusterBlockId  index, int *  num_primitives, const pugiutil::loc_data &  loc_data, ClusteredNetlist *  clb_nlist  )

static

XML parser to populate CLB info and to update nets with the nets of this CLB.

Parameters

clb_nlist	Array of CLBs in the netlist
index	index of the CLB to allocate and load information into
loc_data	xml location info for error reporting

processPb()

static void processPb ( pugi::xml_node  Parent, const ClusterBlockId  index, t_pb *  pb, t_pb_routes &  pb_route, int *  num_primitives, const pugiutil::loc_data &  loc_data, ClusteredNetlist *  clb_nlist  )

static

XML parser to populate pb info and to update internal nets of the parent CLB.

Parameters

Parent	XML tag for this pb_type
pb	physical block to use
loc_data	xml location info for error reporting

processPorts()

static int processPorts ( pugi::xml_node  Parent, t_pb *  pb, t_pb_routes &  pb_route, const pugiutil::loc_data &  loc_data  )

static

read_netlist()

ClusteredNetlist read_netlist	(	const char *	net_file,
		const t_arch *	arch,
		bool	verify_file_digests,
		int	verbosity
	)

Initializes the clb_nlist with info from a netlist.

Parameters

net_file

Name of the netlist file to read

set_atom_pin_mapping()

static void set_atom_pin_mapping ( const ClusteredNetlist &  clb_nlist, const AtomBlockId  atom_blk, const AtomPortId  atom_port, const t_pb_graph_pin *  gpin  )

static
