static

format_coordinates()

static void format_coordinates ( int &  x, int &  y, std::string  coord, ClusterNetId  net, const char *  filename, const int  lineno  )

static

Parse coordinates in the form of (x,y) into correct x and y values.

format_name()

static std::string format_name ( std::string  name )

static

process_global_blocks()

static void process_global_blocks ( std::ifstream &  fp, ClusterNetId  inet, const char *  filename, int &  lineno  )

static

This function goes through all the blocks in a global net and verify it with the clustered netlist and the placement.

process_nets()

static void process_nets ( std::ifstream &  fp, ClusterNetId  inet, std::string  name, std::vector< std::string >  input_tokens, const char *  filename, int &  lineno  )

static

Check if the net is global or not, and process appropriately.

process_nodes()

static void process_nodes ( std::ifstream &  fp, ClusterNetId  inet, const char *  filename, int &  lineno  )

static

process_route()

static void process_route ( std::ifstream &  fp, const char *  filename, int &  lineno  )

static

Walks through every net and add the routing appropriately.

read_route()

bool read_route	(	const char *	route_file,
		const t_router_opts &	router_opts,
		bool	verify_file_digests
	)

Reads in the routing file to fill in the trace.head and t_clb_opins_used data structure.

Perform a series of verification tests to ensure the netlist, placement, and routing files match
