Report clocks
Syntax
report_clocks [‑file <arg>] [‑append] [‑return_string] [‑quiet] [‑verbose]
[<clocks>]Usage
| Name | Description |
|---|---|
[-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 |
[-return_string]
|
return report as string |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<clocks>]
|
List of clocks Default: * |
Description
Returns a table showing all the clocks in a design, including propagated clocks, generated and auto-generated clocks, virtual clocks, and inverted clocks in the current synthesized or implemented design. More detailed information about each clock net can be obtained with the report_clock_utilization command.
Arguments
-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.
-append option can only be used with the -file option.
-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.
set_msg_config command.<clocks> - (Optional) The clocks to match against the specified patterns. The default pattern is the wildcard '*' which returns all clocks in the design. More than one pattern can be specified to find multiple clocks based on different search criteria.
