RE: R_dut, L_dut and C_dut

Hi Brian:

  I just wanted to point out that for best model creation, it is strongly
recomened that R_dut and L_dut be set to zero (i.e. take your data from Si
simulations with no package).
C_dut represents the output capactiance of the device and is pretty much
unavoidable.
