You can not leave an input pin floating. You have to tie it to hi or low or a known
signal such as clock. Otherwise short circuit current through PMOS & NMOS could happen and waste power consumption.

please check manual for the following two variables control the netlist output:
verilogout_show_unconnected_pins
verilogout_unconnected_prefix
Usually in scan test, clock is running at a lower frequency. In STA, you can use case analysis to check timing at functional mode and test mode with different timing constraints. Ignore timing on scan path is dangerous.
