| # Add a \"device\" property to the layout of specific PDK primitive |
| # devices that do not extract as intended. This includes, for |
| # example, RF devices (which extract as non-RF devices), vertical |
| # parallel plate capacitors (which extract as metal wires), and any |
| # other device that is not represented in magic's \"extract\" section. |
| # |
| # This uses the method introduced in magic version 8.3.298 using |
| # property "device" with value "primitive", so that the subcell is |
| # output to the netlist without a corresponding subcircuit entry or |
| # black box entry, as the device is assumed to be defined in the PDK. |
| # But it is necessary to make sure that the ports are in the correct |
| # order for the PDK device. |
