Internal Error: SubSystem VPR20KMAIN

Hi All: I've just recently ran into a problem about 65% though the fitter stage of my design: Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/altera_arch_common/altera...

Hey Pete, I had a look at both of those errors and they're completely unrelated to one another, which is unusual (Internal Errors are almost always easily reproducible).

Given that the error changes when you reboot your computer, I'm wondering if you might have some faulty RAM. Why don't you give the MS RAM checker (http://oca.microsoft.com/en/windiag.asp) a spin and report back here? If it doesn't turn up anything we'll have a closer look.

Cheers, Adrian
