memory error at plotting

[Frank Nitsche]

Hello everyone,

we've got a problem using IC51415 when plotting large data files. When
we try to plot the wafeforms of a noise analysis (regardless if we
plot from ADE or via ocean script) we got the following error and
IC51415 crashes:

*Error* Insufficient virtual memory: Malloc failed - nil

Is there any environment variable within IC51415 where we can increase
the virtual memory?

Any help is appreciated.

I fear that using 64 bits executable is the only solution for the memory.
And as this is not my part, I don't know if they are available for the
plotting tool in 5.1.41 or even in 6.1.x nor if there are work around such
as tools able to split the wafeforms so that they are plottable.

I come to think, there is another factor -- but it asn't be pertinent for
me, even at home, for such a long time that I had forgot about it -- what's
your total swap space? Depending on what the other process consume,
increasing it could solve the virtual memory problem (but you risk spending
time in swapping, the only solution is then increasing the physical memory)

Hi Frank,

check cdsdoc for "CDS_WAVESCAN_MAXHEAP".

Viele Gruesse,
