I am a beginner of XL Layout and I have a question regarding the auto generating basic layouts from schematic. According to some tutorial materials, in the Virtuoso XL Layout window, after clicking Design->Gen From Source, I should be able to see both the boundary box and instance cells. However, the only thing that I can see is the boundary box. (in the original schematic, I have mos, cap, res etc) By the way, I am using IC5141. Thanks.
