create_p2p_delays
Usage
create_p2p_delays [-clock_filter <names>] [-clock_hold] [-clock_setup] [-from <names>]
[-min_tco] [-min_tpd] [-tco] [-th] [-to <names>] [-tpd] [-tsu]
Options
-clock_filter <names>: Valid clocks for clock analyses
-clock_hold: Option to report clock hold paths
-clock_setup: Option to report clock setup paths
-from <names>: Valid sources
-min_tco: Option to report minimum tco paths
-min_tpd: Option to report minimum tpd paths
-tco: Option to report tco paths
-th: Option to report th paths
-to <names>: Valid destinations
-tpd: Option to report tpd paths
-tsu: Option to report tsu paths
Description
Creates a data structure with sources, delays, and clock paths for each keeper. This data is required by
other commands such as "get_delay_path" or "get_clock_delay_path".
Use the options to filter specific paths between keepers.
A keeper is a node of the type pin, register, or clock.
Example
# Print the longest paths from source clock
# to destination register pairs
