Warning: Some components automatically only loaded with IO-models!
Not all the components in the library have a model. Some components has been automatically loaded with IO-models. These simple models are used if no model type is detectable. IO-models (I/O=input/output) only define the behaviour of a pin disregarding the functionallity of the ic. A high impedance input is simply modeled as a high impedance resistor connected to ground. The pin function determines the pin model.
