report_phys_opt [‑file <arg>] [‑append] [‑return_string] [‑quiet]


Name Description
[-file] Output file
[-append] Append the results to file
[-return_string] Return report as string
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution




Reports the results of the fanout driver replication and load redistribution optimizations performed by the phys_opt_design command.


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

Note: If the path is not specified as part of the file name, the file will be written into the current working directory, or the directory from which the tool was launched.

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

Note: The -append option can only be used with the -file option.

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

Note: This argument cannot be used with the -file option.
-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.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.


The following example reports the physical optimizations performed in the current design by the phys_opt_design command:

report_phys_opt -file C:/Data/physOpt_Report.txt
