scale in hspice simulation

[lhlblue]

i have a circuit including subckt A B and C, now i want to observe how the post-simulation parasitics of C affect the total circuit, so i extracted the pex netlist of subckt C, and to replace the corresponding part in pre-simulation netlist using the pex netlist (of C). but in pre-simulation, the unit of W and L is m, whlie the unit of the pex netlist is um, so i cannot simulate them together. how to deal with this?
i see in pex rule file, there is a line 'UNIT LENGTH U', if i change it to 'UNIT LENGTH M', then is the pex netlist extracted using the option 'UNIT LENGTH M' right also? if not, is there any other way to sovle this problem?
thanks.

I think S-parameter-scaling should work for your subcircuit, s. this clipping:

ok, thanks.
