#       Transfer the timing netlist from Quartus to a zdb tcl file.
#
#       Script that can be executed in TimeQuest to transfer the timing
#       netlist.
#
#       IMPORTANT: This script is NOT a *Vision Userware.
#
#       It is a Tcl script that can be
#       executed in Altera's Quartus/TimeQuest tools to export the netlist
#       for RTLvision PRO as a Tcl Userware file.
#       Run this script as:
#       ```
#       quartus_sta -report=getNetlist.tcl <Project>
#       ```
#       It will generate the file `<Project>.rtlvision.tcl` containing
#       `$db load ...` commands. This file can be loaded as a Userware
#       in RTLvision PRO.
