• File New Default.tch / Metric.tch (inches/mm).

• then automatically, Layout asks the netlist file (.MNL) ,

• next the name of the main output file (.MAX)

• next the footprints of the components. .../...

Use the library EVALBOARD.LLB for the main components;some footprints are missing, like the crystal resonator (Takee.g., a capa footprint. The crystal is not needed when usingthe emulator).
