report_skew
Usage
report_skew [-append] [-detail <SUMMARY|PATH_ONLY|PATH_AND_CLOCK|FULL_PATH>] [-exclude
<Tcl list>] [-fall_from_clock <names>] [-fall_to_clock <names>] [-file <name>] [-from
<names>] [-from_clock <names>] [-greater_than_skew <slack limit>] [-include <Tcl list>]
[-npaths <number>] [-panel_name <name>] [-rise_from_clock <names>] [-rise_to_clock
<names>] [-show_routing] [-stdout] [-through <names>] [-to <names>] [-to_clock <names>]
Options
-append: If output is sent to a file, this option appends the result to that file.
Otherwise, the file will be overwritten
-detail <SUMMARY|PATH_ONLY|PATH_AND_CLOCK|FULL_PATH>: Option to determine how much
detail should be shown in the path report
-exclude <Tcl list>: A Tcl list of parameters to exclude during skew analysis. This list
can include 1 or more of the following: utsu, uth, utco, from_clock, to_clock,
clock_uncertainty, input_delay, output_delay
-fall_from_clock <names>: Valid source clocks (string patterns are matched using Tcl
string matching)
-fall_to_clock <names>: Valid destination clocks (string patterns are matched using Tcl
string matching)
-file <name>: Sends the results to an ASCII or HTML file. Depending on the extension
-from <names>: Valid sources (string patterns are matched using Tcl string matching)
-from_clock <names>: Valid source clocks (string patterns are matched using Tcl string
matching)
-greater_than_skew <slack limit>: Limit the paths reported to those with skew values
greater than the specified limit.
-include <Tcl list>: Tcl list of parameters to include during skew analysis. This list
can include 1 or more of the following: utsu, uth, utco, from_clock, to_clock,
clock_uncertainty, input_delay, output_delay
-npaths <number>: Specifies the number of paths to report for each latest and earliest
arrival skew result (default=1)
-panel_name <name>: Sends the results to the panel and specifies the name of the new
panel
-rise_from_clock <names>: Valid source clocks (string patterns are matched using Tcl
string matching)
-rise_to_clock <names>: Valid destination clocks (string patterns are matched using Tcl
string matching)
-show_routing: Option to display detailed routing in the path report
-stdout: Send output to stdout, via messages. You only need to use this option if you
have selected another output format, such as a file, and would also like to receive
messages.
-through <names>: Valid through nodes (string patterns are matched using Tcl string
matching)
-to <names>: Valid destinations (string patterns are matched using Tcl string matching)
-to_clock <names>: Valid destination clocks (string patterns are matched using Tcl
string matching)
