Thanks for the wisdom on the last newbie question. I managed to finish a simple schematic (1 pHEMT, one SiGe bipolar, and one fast op amp--a whole 22 parts altogether).
Now for a board layout, and the next question. I figured out how to set the design rules to make a four-layer board with two cores, with prepreg in between. Now I need to make a ground plane. So far, I've done:
set layer 2 to be net GND, supply plane box checked in the DISPLAY dialogue
POLY GND draw the polygon autoroute (just for test purposes, honest)
The autoroute fails because it's trying to put everything on layer 1, and it ignores the ground plane almost entirely--it routes the grounds, and it makes no vias or thermals in the ground plane. Except for one--it makes a big hole under the Pin 1 mark on the IC package, which is drawn as a wire in the package editor.
How do I get Eagle to recognize the ground plane as a ground plane?
How do I get the autorouter to use more than one layer?
