I'm trying to simulate an L2577-adj circuit in Proteus software but I can't find it in the local library that come with Proteus.
I could, however, find it in component search engine , but after downloading the files and importing them with Proteus they show up, but I get no model specified error.
I found out that if I mark the checkbox attach hierarchy module it should work, and that's what happened: the simulation works but the item that I imported does not work at all. What am I doing wrong?
