Weston,

We've been performing ICX evaluations and have tested it on several
designs. It's good to hear positive comments on support and run time. We
also, like Arjan, have experienced real long run times. We found over
constrained synthesis can run for a real long time. We ran a lot of test,
on by chance a Sparc 1, and it was painful. We're now running it on an
UltraSPARC 60 and it's much more bearable.

On simulation time we learned to be careful with what we're asking the tool
to do. It's easy to ask it to check everything interactively, or in batch,
but run time can be very long. By turning off what we don't want to check
at that point in time we're able to speed things up quite a bit.

Relative to support, are you using the standard Mentor Hot Line Support
Agreement or do you have something special in place? We see support as a
critical success factor.

We've has some real success with the tool and just took hardware lab data
to help evaluate simulation accuracy. Our main issues so far is the Mentor
Interface and the ECO Process. We do a lot of concurrent engineering and we
have to re-establish the checking and rules set-up every time we update, a
very inefficient process.

To further address a question of Arjan's, our evaluations have been
focusing on critical nets design with IS, bulk routing with CCT and then
final verification with IS. So far so good.

Regards;

Greg Heiler

Arjan,

I use IS quite successfully on very large boards. I can translate a board
with 2000 nets in about 20-30 minutes. I just synthesized 300 nets with
relative timing rules over night. It sounds to me like you're running on a
Sparc1 or something. You should talk to your ICX application specialist.
I've found ICX support to be phenomenal! Give them a chance to help you.

Regards,
Weston Beal

Hello all,

Since a few months we're working with
Mentor Graphics Interconnectix.

After a while we found out, that synthesizing
just a few critical nets, just as running conversion
scripts or processing rules, easily can take
some hours.

To us it seems that the usage of Interconnectix,
is too time consuming, to benefit from it, as
we compare it's results to some new autorouters.

We're told that a lot of companies use Interconnectix
nowadays. What is your experience, is it worth
spending so much time or is it just usefull for
PWB's with a few critical tracks.

What is your opinion?

Thanks in advance,
