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)
