Hi All,
I am working on this PI tool from beta version of the first release and
presented a paper on this tool in Mentor user forum held @ Bangalore. I have
given many inputs and found bugs which I communicated to the team in earlier
days, but unfortunately we don't have solution yet.
Particularly this short problem I came across this 9 to 12 months
before and because of that only they raised this SR I believe. But after that
they had two releases and they also confirmed that it is solved in the recent
releases. Based on this confirmation only my team has purchased this tool for
our next project.
But now also we are facing same issue, so I think there is a
communication gap somewhere which Mentor needs to fill. As Steve Kaufer pointed
if it is duly addressed in coming days we are happy.
Thanks & Regards
Lakshminarayanan. S

Hi George,
That's the current "official" status on the Mentor support site. But luckily
for HyperLynx users, the engineering manager (that would be me) watches
customer feedback carefully, and adjusts plans as needed. I've seen a few
similar reports recently from other users, so my development team was already
investigating whether some quicker improvements can be made. Feel free to
contact our support team, your AE, or me directly if you want to discuss
further. That would be off-line, of course: although I admit that get a kick
out of seeing competitor's software issues getting aired publicly, that's not
really the purpose of this forum.
Regards,
Steve Kaufer,
Director of Engineering, High-Speed Tools

Has anyone contacted a Mentor AE? Perhaps they are aware of the problem, if it
exists, and have a fix.
