Quartus II 10.1 web edition dropped support for Virtual Pins, it seems

Web editions never had virtual pins (what I remember) but I installed the 10.1 Web version using the Altera Installer (at the download subscription page) and found the virtual pins feature enabled.

Well, it's kind of strange. I have a design which has lots of virtual pins, which compiles fine on 9.1sp2; but when I load it in 10.1, even though it *recognises* the virtual pin assignments in the editor, I get a warning during compilation that virtual IO will only be enabled in the subscription version, and when I compile I end up with an error saying that it is missing 133 output pins to accomodate for all the pins I'm trying to use (which were supposed to be virtual pins of course, but didn't register as such, apparently).

as far as i understand, Virtual Pins are supposed to be unique to Subscription Edition since they are part of the Incremental Compilation flow

Then they slipped up on the restrictions of Quartus II 9.1sp2 Webedition, because it definitely worked there.

you may file an enhancement request in an SR. Virtual Pins (or something similar) are useful for doing resource or timing estimates even though they are intended for use in Incremental Compilation

Maybe Altera now and then surprises someone to get them hooked :lol:
