====== Using Tcl Commands to Highlight Clock Trees in the Layout Window ======


===== Question: =====

How do I highlight clock trees in the IC Compiler layout window by using Tcl commands?

===== Answer: =====


In IC Compiler version 2008.09 or later, you can use the following commands to highlight
clock trees in the layout window:
<code tcl>
gui_set_setting -window [gui_get_current_window -types Layout -mru] -setting vmName -value "CLOCK_TREES"
gui_set_setting -window [gui_get_current_window -types Layout -mru] -setting showVisualMode -value true
gui_load_clock_tree_vm  -exclude_cells  -clock_trees { sys_clk { { 0 1 2 3 4 5 } { } } }
</code>
Note: sys_clk is the clock tree that has six levels (0 to 5).
