# Get STA timing report from TimeQuest.
#
# IMPORTANT: This script is NOT a RTLvision PRO Userware.
#
# It is a Tcl script that can be executed in Altera's
# TimeQuest tool to generate an Userware to visualize timing paths.
#
# Run this script as:
# ```
# quartus_sta -report=sta_report.tcl <Project>
# ```
# It will generate the file `<Project>.rtlvision.tcl` that can be loaded
# as a Userware in conjunction with the PathVision Userware.
