+====== Script to Highlight Launch and Capture Clock Paths in the Layout  ======
+You can use the get_timing_paths command with the get_attribute command to create collections of the timing paths,
+and use the gui_change_highlight command to highlight each collection of paths with a unique color in the GUI.
+The example below uses the get_timing_paths and gui_change_highlight commands to highlight the paths for the launch and capture clocks for the
+<nowiki>
+I_SDRAM_TOP/I_SDRAM_READ_FIFO/reg_array_reg_1__31_/D
+</nowiki>
+register input.
+<code tcl>
+set path [get_timing_paths -to I_SDRAM_TOP/I_SDRAM_READ_FIFO/reg_array_reg_1__31_/D \
+   -group SDRAM_CLK]
+gui_change_highlight -color yellow -collection $path
+set launch_clock [get_timing_paths -through [get_attribute [get_attribute $path startpoint_clock] sources] \
+   -to [get_attribute $path startpoint]]
+gui_change_highlight -color green -collection $launch_clock
+set capture_clock [get_timing_paths -through [get_attribute [get_attribute $path endpoint_clock] sources] \
+   -to [get_attribute $path endpoint_clock_pin]]
+gui_change_highlight -color blue -collection $capture_clock
