The -type option returns a string indicating the type of delay that this point represents in the path.
Possible return values for -type are:
Example
# Define a few helper procedures to print out points
# on a path, and the path itself
proc get_clock_string { path clk } {
set clk_str ""
set clk_id [ get_path_info $path -${clk}_clock ]
if { $clk_id ne "" } {
set clk_str [ get_clock_info $clk_id -name ]
if { [ get_path_info $path -${clk}_clock_is_inverted ] } {
append clk_str " (INVERTED)"
Value Description
(empty) Unknown transition
r Rising output
f Falling output
rr Rising input, rising output
rf Rising input, falling output
fr Falling input, rising output
ff Falling input, falling output
Value Description
cell Cell delay
clknet Lumped clock network delay
clksrc Clock source. Used to ensure that the end-point of a clock segment is marked in the
path when source latency is specified, or when the actual path cannot be found.
comp PLL clock network compensation delay
ic Interconnect delay
iext External input delay
latch Clock latch time
launch Clock launch time
loop Lumped combinational loop delay
oext External output delay
re Routing element (only for paths generated with the -show_routing option)
srclat Source latency for a clock segment. This will appear if latency was specified between
two clocks, or if a path could not be found between them.
unc Clock uncertainty
utco Register micro-Tco time
utsu Register micro-Tsu time
uth Register micro-Th time
