Hello eveyone! I have some questions regarding doing layout in magic. In my understanding
maglef files allows one to see only the metal layers, not the underlying diffusion, well or poly layers.
If I set the
MAGTYPE variable in
.magicrc file to
maglef then a standard cell placed using
Options->Library Manager->place then
cell->Expand Toggle shows me only metal layers with zero DRC errors. However, if I set the
MAGTYPE variable to
mag then I can see all the internal transistor layers but there are DRC errors in the cell.
My question is
1. Which
MAGTYPE is correctly showing the DRC errors?
2. For io pads (eg. vdda_hvc_pad),
maglef shows metal layers but
mag hardly shows anything. Is that the correct behavior? Should I update my io library to a newer version? (screenshot attached)
My second question is related to how to make nwell and substrate contacts.
3. What are the layer and contact names in magic to make nwell taps and substrate taps?
4. Do the skywater standard cells come with well and substrate contacts?
