A useful idiom to find the driver pin for a net is the following. get_pins -of_objects [get_net net_name] -filter direction == output

This should be get_pins -of_objects [get_net net_name] -filter "direction == output", I think. Using the line directly results in obscure errors like

Warning: fast_characterise.tcl line 12, patterns argument not supported with -of_objects.
Error: fast_characterise.tcl line 12, unsupported pin -filter expression.

Correct. The other option is to remove the spaces in the filter expression so it is one tcl token. I will update the docs.
