Quartus 10.0 too buggy?

where do you see rev2?

the GUI changed in 10.0 and some of the changes have let productivity suffer. some of this is related to installation which is well documented by Altera, or else shows up in the Release Notes where work arounds are suggested. i expect we will see some workflow enhancements in the service packs or next versions of Quartus as the software becomes more mature with the new GUI library

in general the initial release seems to be more problematic as new features are added they can be unstable or cause previously working things to break. service packs tend to clean up pretty well, i would say 9.0sp2 and 9.1sp2 are very strong releases. the 10.0 release might be a bit more painful than other recent releases because of the GUI switch
