RE: [IBIS-Users] [dV/dt_r] and [dV/dt_f]

Nam,
 
Section 9 of the IBIS specification should
answer your question...

Subject: [IBIS-Users] [dV/dt_r] and [dV/dt_f]

Hi,

Table 3.1 of page 19 of IBIS cookbook for IBIS Version 4.0 recommends 4
V-T waveforms:

1R + 1F driving 50 Ohms to Vcc

1R + 1F driving 50 Ohms to GND

Note that from this set of 4 waveforms, I can derive 2 dV/dt_r and 2
dV/dt_f

How do I decide which ones would be going into IBIS keywords [dV/dt_r]
and [dV/dt_f] ?

Thank you in advance,

Nam
