Do you know of a usable viewer which can handle that format ?
I couldn't get to grips with the gEDA thing.
I could have been trying ACS, 'cos I'm working mostly in CMOS
these days, but it doesn't look like I can run a big simulation
and store all the results. I need ALL the results, so that I
can track down the problem if (when) it doesn't work ;-)

I may have asked this before, but does ACS store all the
results till the end and then print them out, or does
it output the data after each time-step/dc-step ?
I've had trouble at TI and here (ADI) with simulators
which store all the results till the end, and then
write them out to disk. This means that you're limited
not only in circuit size, but in simulation size too.
Simulators like PSPICE and Berkeley Spice3 are limited
only by circuit size, assuming your disk is big enough
to store all the results. The trick is to read the results
back in quickly when you want them.
