Good afternoon SI gurus,
I have a MCM device that has no models and am wanting to create a test PCB with
the purpose of extracting lab data to then create models for it. The Hyperlynx
tool has an application that allows one to create custom IC Models called .MOD
Models.
There could be 2 goals for this effort,
1. Modeling the I/O @ the MCM
MCM IO Drivers tested with a 50ohm trace into a 50ohm PD and a 50ohm PU
using the voltage divider equation for the output high & low impedance.
MCM IO RECEIVERS.
I AM UNSURE OF HOW TO TEST FOR THE MCM RECEIVER IO FOR THE PURPOSE OF
CREATING A SIMULATION MODEL FROM LAB DATA???
Probably get an FPGA to drive to the MCM receiver thru a 50ohm trace...not sure
how to characterize the input resistance - measure current thru a 50 ohm series
resistor as well as voltage to come up with the Input resistance.....I could
play with the clamp diode settings in the Hyperlynx tool until I saw a similar
OS/US conditions when compared to the scope data....??
2. Modeling the IO at the die bond wire (not sure I have access but will
assume for now - maybe :) )
Going out on a limb here since I have never probed a signal at the bond wire
(I imagine very fragile work if even possible)
The goal would be the same as above except the combination of MCM data from #1
- #2 = what I would define as the parasitics not including the IC die.
