report_skew
Usage
report_skew [-append] [-detail ] [-exclude
] [-fall_from_clock ] [-fall_to_clock ] [-file ] [-from
] [-from_clock ] [-greater_than_skew ] [-include ]
[-npaths ] [-panel_name ] [-rise_from_clock ] [-rise_to_clock
] [-show_routing] [-stdout] [-through ] [-to ] [-to_clock ]
Options
-append: If output is sent to a file, this option appends the result to that file.
Otherwise, the file will be overwritten
-detail : Option to determine how much
detail should be shown in the path report
-exclude : 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 : Valid source clocks (string patterns are matched using Tcl
string matching)
-fall_to_clock : Valid destination clocks (string patterns are matched using Tcl
string matching)
-file : Sends the results to an ASCII or HTML file. Depending on the extension
-from : Valid sources (string patterns are matched using Tcl string matching)
-from_clock : Valid source clocks (string patterns are matched using Tcl string
matching)
-greater_than_skew : Limit the paths reported to those with skew values
greater than the specified limit.
-include : 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 : Specifies the number of paths to report for each latest and earliest
arrival skew result (default=1)
-panel_name : Sends the results to the panel and specifies the name of the new
panel
-rise_from_clock : Valid source clocks (string patterns are matched using Tcl
string matching)
-rise_to_clock : 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 : Valid through nodes (string patterns are matched using Tcl string
matching)
-to : Valid destinations (string patterns are matched using Tcl string matching)
-to_clock : Valid destination clocks (string patterns are matched using Tcl
string matching)
