Dear SI gurus,
When somebody jump out and help us out of troubles, we always express our
appreciation to them. Here, I want to show my thanks to whom, helping me at
my questions.
 
Thank you for your invaluable comments.
 
Here is the summary,
Dr. Edward & Scott: a different approach: ac frequency sweep with spice.
Willis: setup a big topology sweep.
Doug: minimum of test sets.
Farrokh: point out all the components, which shall be included in
simulation.
Dennis: point out some critical factors while designing scsi backplane.

Subject: [SI-LIST] : How to simulate SCSI backplane with 15 slots?

Dear SI gurus,
 
One question regarding SI simulation for SCSI backplane. How do I define the
worst case of SCSI backplane with 15 slots for 15 SCSI drives?
 
Shall I do the SI simulation, theoretically, for all combinations of 15 SCSI
drives?
There are huge combinations -- the number of drives mixed with the number of
slots (location on the backplane). Based on my knowledge, I would like to
put drives on even spaces for the best case of SI simulation. for example,
three drives on slot 1st,8th, and 15th. For the worst case, intuitively, I
would like to put them on slot 1st,2nd, and 3rd because of far away from end
terminators.
 
The question is that how to assure the worst case for simulation? Or,
doing all combinations is only way to do even it is exhaustive.
 
Your comments are highly appreciated.
