* Transistor and resistor types have long and short names. In Electric,
34
* schematic and layout primitive transistors have different names. NCC uses
35
* the long name to match types between the schematic and layout. Except for
36
* the basic NMOS and PMOS types, each schematic transistor contains an
37
* annotation specifying which layout transistor it matches.
38
* The short names are used internally for NCC print-outs because the long
39
* names are too verbose.
41
* Scalable transistors, in the layout, have a different long name than
42
* regular transistor but map to the same type as ordinary layout transistors.
