Physical Device
Component: For CMOS device, major components are source, drain and fate.
Connector: n-channel for NMOS, p-channel for PMOS
Interface:
Link:
Example: Take the following conducting NMOS for example,
AS the above conducting NMOS example, we could say there are three components: Gate, Source and Drain, n-channel function as connector of Source and Drain. So, we may have the following simplified xADL-like figure:
