Hello,
I am doing a simulation on Oracd 10.5 student edition. I have schematics i obtained from some previous labs and they work fine, even if I re-use these components in other circuits I made. But when I use new components I obtaine this message: Model Q2N3905 used by Q_Q4 is undefined
In this case I am using the 2N3905 transistor for the first time. But it does this for allohther omponents. How do I get by that ? I searched on google and did not find anything interesting. thank you
Ken
