The Analyzer Window
The AnalyzerWindow shows the values of the circuit's input and output
signal values as a function of time.
Signal values recognized by the system are:
-
signal 1;
-
signal 0;
-
signal u (unknown).
To represent the input 0 of a gate g1 we write the following
way: g1i0, and ouput 0 of gate g1 as: g1o0
(unless they are connected to a wire, in which case there is no need to
have a name for the pins of the gate).
This notation is used throughout the AnalyzerWindow to indicate which
signals were applied to which wires.
Let's examine a snapshot of the AnalyzerWindow:
Figure 1
We read the information presented in this window as follows:
-
The evolution of the signal values on the input 0 of gate g2
is shown on the graph across notation g2i0. The signal value on g2i0 is
0 up to moment 1, then it becomes 1.
-
The signal on the input 0 of gate g3 (g3i0) is constantly 0.
-
The output signal of the circuit, identified with g1o0 (the output of g1)
is unknown up to time 1, then changes to 1 for time 2, and eventually
changes to 0.
-
The signal value of wire 1 (w1) is unknown at time 0, it is
1 at time 1, then it is 0 from time 2 on.
-
The signal value of wire 2 (w2) is unknown at time 0,
then it changes to 1 at time 1.
