I'm limited to QFP packages, though. I picked the 3A family for some reason, ah, power - the 3A doesn't need a 2.5v interface block. I haven't tried synthesizing into the 3A yet to see how much space I'm using. > Why not just use chipscope?

Well, if chipscope is freely downloadable, I'm OK with that. > Hard to believe the LA expects signals that fast without active probes. Well, I said Ms/s, not MHz. It's mostly useful for measuring skew and jitter relative to other pins. I usually run at one of the slower speeds, as the LA's compression doesn't work at the fastest speed. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
