Functional analysis of a combinational network




Load the following circuit in the d-DcS, with a click on the figure:

Using the functional simulation , compile a truth table with the results of the functional simulation.

Then, with the timing simulation , show its behavior for all the combinations of input values. A suitable test sequence is available in the Timing Diagram window.

This circuit is a "decoder":

  • What is the role of S1 and S0?
  • What is the role of EN?
  • What is the relation between the number of inputs and the number of outputs?
