Function Documentation

count_netlist_clocks()

int count_netlist_clocks

(

)

Count how many clocks are in the netlist.

get_channel_occupancy_stats()

static void get_channel_occupancy_stats ( )

static

Determines how many tracks are used in each channel.

get_num_bends_and_length()

void get_num_bends_and_length	(	ClusterNetId	inet,
		int *	bends_ptr,
		int *	len_ptr,
		int *	segments_ptr
	)

Counts and returns the number of bends, wirelength, and number of routing resource segments in net inet's routing.

length_and_bends_stats()

void length_and_bends_stats ( )

static

Figures out maximum, minimum and average number of bends and net length in the routing.

load_channel_occupancies()

static void load_channel_occupancies ( vtr::Matrix< int > &  chanx_occ, vtr::Matrix< int > &  chany_occ  )

static

Loads the two arrays passed in with the total occupancy at each of the channel segments in the FPGA.

print_lambda()

void print_lambda

(

)

Finds the average number of input pins used per clb.

Does not count inputs which are hooked to global nets (i.e. the clock when it is marked global).

print_wirelen_prob_dist()

void print_wirelen_prob_dist

(

)

Prints out the probability distribution of the wirelength / number input pins on a net – i.e. simulates 2-point net length probability distribution.

routing_stats()

void routing_stats	(	bool	full_stats,
		enum e_route_type	route_type,
		std::vector< t_segment_inf > &	segment_inf,
		float	R_minW_nmos,
		float	R_minW_pmos,
		float	grid_logic_tile_area,
		enum e_directionality	directionality,
		int	wire_to_ipin_switch
	)

Prints out various statistics about the current routing.

Both a routing and an rr_graph must exist when you call this routine.
