Tutorial 6: Useful special devices



 

1. Digital devices

The digital devices reside in the "digital.lbr" library. Their main purpose is to model small digital parts of your circuitry using transient analysis. From the eagle control panel, double click onto the "count4" schematic symbol to see a (pure digital) application example:
 


 

The lower two green textlines define the reset and the clock sources to stimulate the counter. I have added some voltage to the different measurement instrument channels to separate the waveforms from one another.
 

2. Voltage controlled Resistors, Capacitances and Inductances

These are useful if you want to optimize your circuit. You may use e.g. the voltage controlled capacitance to trim your filter circuit to resonance in transient analysis.
Another application would be to model real parts like e.g. a potentiometer.

3. Abstract Parts

Adder, Subtractor, Multiplier and other parts will help you to model parts of your circuitry on a conceptual level before going the hard way to implement the function with real parts.
