RE: About relationshipp between R_pkg,C_pkg,L_pkg and R_dut, C_du t, L_dut

Greetings:
 
  the R_pkg, C_pkg and L_pkg values are used to specify the minimum and
maximum values of the pin resistance, capacitance and inductance for the
entire package. These values appear under the [Package] keyword. The R_dut,
C_dut and L_dut only represent the electrical characteristics of the pin
used when gathering data for the [Rising Waveform] and [Falling Waveform]
keywords. The 'dut' in R_dut etc. means 'device under test'.
 
(Please note that it is recomended to gather the data in the waveform tables
with R_dut, C_dut and L_dut set to zero).

Subject: About relationshipp between R_pkg,C_pkg,L_pkg and R_dut, C_dut,
L_dut

Hi,
    I found that the R_pkg,C_pkg,L_pkg and R_dut, C_dut, L_dut have the very
similar functions. But form the IBIS Specification V3.2, I found they are
different. So I am confused, and want to the relationship between them.

Thanks in advance!
