Report the list of correct SIM_DEVICE attribute values for cell types in the target part


report_sim_device [‑part <arg>] [‑file <arg>] [‑append] [‑return_string]
    [‑quiet] [‑verbose]




Name Description
[-part] Part
[-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




Cells with the SIM_DEVICE attribute may have slightly different behavior when applied in different families of devices. The value of SIM_DEVICE directs the simulator to match the behavior of the cell to the target device. Use report_sim_device to report the correct SIM_DEVICE attribute value to use for cell types in the target part.

Important: Unless -part is specified, the currently loaded part is used as the target part for this command.


-part <arg> - (Optional) Target part

-file <arg> - (Optional) Write the SIM_DEVICE 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.

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

-return_string - (Optional) Directs the output 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 generates the report of SIM_DEVICE attributes and correct values to use for the xcvu065-ffvc1517-1-i part.
