    [‑return_string] [‑quiet] [‑verbose] [<objects>]

Usage

Name	Description
`[-max_paths_per_endpoint]`	Number of branches per endpoint to report traces for Default: 1
`[-column_style]`	Style for path report columns: Values: variable_width, anchor_left, fixed_width Default: variable_width
`[-file]`	Filename to output results to. (send output to console if -file is not used)
`[-append]`	Append the results to file, don't overwrite the results file
`[-no_header]`	Do not generate a report header
`[-of_objects]`	Report constant paths for these constant paths
`[-return_string]`	Return report as string
`[-quiet]`	Ignore command errors
`[-verbose]`	Suspend message limits during command execution
`[<objects>]`	Endpoint pins or instances

Description

Reports constant path objects that meet the specified criteria.

Arguments

-max_paths_per_endpoint – Specify maximum number of paths to report per constant endpoint object.

Note: By default, 1 path per endpoint has been reported.

-column_style [ variable_width | anchor_left | fixed_width ] - (Optional) Specify the format of the timing path portion of the timing report output.

Note: The default format is anchor_left.

-file <arg> - (Optional) Write the report into the specified file. The specified file will be overwritten if one already exists, unless -append is also specified.

-append - (Optional) Append the output of the command to the specified file rather than overwriting it.

-no_header – (Optional) Will not print header which contains information about tool, system, device, and design on top of the report.

-of_objects – (Optional) Report constant paths for specified paths. For object retrieving get_constant_paths command can be used.

-return_string - (Optional) Directs the output to a Tcl string rather than to the standard output. The Tcl string can be captured by a variable definition and parsed or otherwise processed.

-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.

-verbose - (Optional) Temporarily override any message limits and return all messages from this command.

<objects> - (Required) Design cell(s) or pin(s) object list to report.

Examples
