From: Nial Stewart on 27 May 2010 05:46 Just to even things up, I've used A and X devices in the last few years and know and prefer the Altera tools much more, but..... A client was hoping to use Altera's PCI Lite (free master/target 32bit/33MHz) core for a project I'm currently working on. November/December last year I tried integrating it in the SOPC system I was building but it was broken. The values set in the configuration pages changed when you saved it and opened it again and when apparently built cleanly, meeting all timing constraints, the PCI card froze the PC I was testing on. It was clear that there had been very litte verification/quality control on this which is unlike Altera, their software mostly just works. IMHO Nial.

That has changed. The ones I buy are available from stock at Mouser and the programming cable is $150 US. In fact, the part I am using the the lowest cost FPGA I can find in a 100 TQFP. It is a flash based XP3C device. The software works as well as anyone's and it is getting the job done. Other than the fact that this footprint has no upward compatible path I have no complaints.
