2016.1 Vivado - (UG888) Tcl script hangs when run from the Text Editor


I am going through the Introduction to Vivado tutorial in (UG888).

I have opened my Tcl file in the Vivado Text Editor and then executed it by right clicking and selecting "Run Tcl". However, after I do so, the Vivado IDE is no longer responding.

It hangs at the following stage:

Starting Power Optimization Task
INFO: [Pwropt 34-132] Skipping clock gating for clocks with a period < 2.00 ns.
INFO: [Pwropt 34-9] Applying IDT optimizations ...
INFO: [Pwropt 34-10] Applying ODC optimizations ...

Running "source my_script.tcl" in the Tcl console works without issues.


The script runs without issue if sourced from the Tcl console.

This issue is resolved in Vivado 2016.2.
