Encounter not buffering scan enable

[design_engineer]

My SCANEN signal has a fanout of over 11000.

I have a set_false_path -from SCANEN in my constraints.

When I run optDesign in Encounter, it is not building a buffer tree on the SCANEN net. Is the false path causing the tool to ignore the fanout violation? But if I take out the false path, then I will fail timing on the scan signal. This will make the tool work unnecessarily to meet timing on test paths I dont really care about.

How do I deal with this?

set_false_path is not causing your problem, there might be a 'set_dont_touch_network' on SCANEN somewhere in your constraints
