Hi,
I've recall having an issue with some special shape for mechanical retention. I
had a net0 that was shorting the power and GND in the hyperlynx database. The
board shape was a little special and the translation convert it into a circle.
This circle shorted many net (including power and GND). I had to remove net0
from your .hyp database. In my case, Hyperlynx was just shutting down.
Maybe you should look at all unusual stuff on your board the could short your
power together.

Subject: [SI-LIST] PI simulation "unrecoverable and unidentifiable" error with
Hyperlinx 8.2
Hi All,
I am helping out one of my colleague for decoupling analysis with hyperlynx
8.2. When tried simulating in boardsim few of the rails (1.8V, VDD1, VDD2
rails) in the board reported an error pointing out that the error is
"unrecoverable and unidentifiable".
The same power rails when exported to the Linesim had problems with different
nets merging together reported as "Net 1.8V and GND are connected and will be
combined to single net "GND_1.8V"
But as per layout this net is clean.
Is there anyone faced similar issue, please share your thoughts. Thanks!
Thanks,
Manoj
