Crash during loading of large (~3GB) av_extracted file

[David Kubalek]

Hi All,

Cadence QRC fullchip parasitc C extraction was performed and outcome
is 3GB large file, which I need to open in Cadence Virtuoso and just
manually check few nodes.

Unfortunatelly Virtuoso crash after some time, when I try to open this
huge file.

Any hint how to handle such a large files?

(define and extract only nets of interest is not prefered solution
here)

Thank you in advance,
David

Hi David,

If I'm not wrong by default the 32bit version is loaded.
You can try command "layout -64".

Also, there could be a limit of "n" x GB per process in your OS.
I'm remember that in the past I've noticed a 3GB limit on some Solaris
(don't remember the version).

BR,
Marcel

If using a CDB version (e.g. IC5141) then there's a maximum size of a single
cellView, regardless of whether you're in 64 bit mode. If in an OpenAccess
enabled version (e.g. IC614, IC615), then that limit is not there, but you'd
probably need to run in 64 bit mode as Marcel suggests.

Andrew.
