Lars -
Gotta go with Giancarlo, I've never seen an Ansoft AE that wasn't totally
concerned with a customer's usage issues. I'm not affiliated. I think your
experience was an anomaly in that regard. Splitting the AE's out from the
discussion, I would have to agree with you that there are issues with the
product that need to be addressed, some of which are not problems when you
view competitors' products. Ansoft makes great products, but they can be a
little unwieldy at times.

Dear Lars,
I cannot agree with you.
I worked at Ansoft for a while and I know by experience that
Application Engineers are really motivated to take care
of the customer problems.
For what I remember .....taking care about the accuracy of the simulation
results and customer satisfaction
is one of the key of Ansoft AE's attitude.
Regards
Giancarlo

Oggetto: [SI-LIST] Re: Ansoft License issue
Hi Aubrey,
You're not the only one disappointed with the way Ansoft is using their
market leading position.
They have done a splendid marketing job, dazzling many people building up
new SI departments with the niftyness of their GUI and an admittedly great
layout import functionality (ansoft links).
However, I could do with a program that converged more often, produced more
physical results and wasn't as much of a memory hog.
I also never saw any of their application engineers really tackling the
question of whether the accuracy their tools provide, is suitable for the
business you're in. 20ps difference in a 10Gb/s eye opening simulated vs.
measured is maybe not a big deal for some companies, but for optical
communication products, for instance, this is not nearly enough. This issue
was carefully sidestepped in the seminar I attended.
Morale: Always test drive more products than one, and prioritize accuracy
over GUI niceness (unless the gui in question is a complete dog,
usabilitywise)
