[SI-LIST] : Which signal integrity tool to use

Jostein,

I have a little bit of experience with the Hyperlynx tool. I think you'll find
that you can come up to speed with it quite quickly. I can also speak for some
of the other tools on the market, which are more complex and therefore take a
longer time to come up to speed. Ease of use is definitely one of Hyperlynx's
strong selling points. I guess you will have to ask yourself which paradigm
best suits your needs.

With any behavioral simulator, you'll want to make sure you do some accuracy
benchmarks. Take a few of your critical components, get the IBIS datasheet and
the SPICE model, and run some comparisons. Here are some questions to ask:

1) Does this circuit do anything advanced, such as feedback or edge rate
control?
2) Does IBIS cover this behavior today?
3) Does my behavioral simulator cover this behavior today?
4) Has the component vendor correlated the IBIS datasheet to hardware?

I have found the people at Hyperlynx to be cooperative in helping you to answer
these kinds of questions.

Good luck in your search.

Subject: [SI-LIST] : Which signal integrity tool to use

Hi,

I'm looking for a signal integrity/EMC tool to use. HyperLynx seems to
be widely used, and a price of about $10k seems reasonable to me.

However, when I look at f.ex. ViewLogic's XTK, the price is about 10x
that of HyperLynx. If these to tools comply to the rule that you get
what you're paying for, then there is a lot of nice stuff that I cannot
do in HyperLynx that I can in XTK or similar expensive signal integrity
tools.

Is my suspicion right? When is HyperLynx not enough? Are you guys out
there generally satisfied with HyperLynx?

Thanks,

Jostein Pettersen
