How can I perform multicorner timing analysis when using a Tcl script file for customizing reports during compilation?

Description

To perform multicorner timing analysis when using a Tcl script file for customizing reports during compilation, your script should include commands to change operating conditions and update the timing netlist between timing corners. Your script should not include commands to delete and recreate the timing netlist between timing corners.

This example shows the commands needed to create custom reports at each available timing corner:

foreach_in_collection op [get_available_operating_conditions] {
    set_operating_conditions
    update_timing_netlist
    post_message "Operating Conditions : [get_operating_conditions_info -name]"
    <custom reporting commands>
}
