Today I wanted to quickly calculate a truth table for a simple boolean equation. Whilst this can be done very simply on paper it becomes tedious with lots of inputs.

A quick Google search found “Logic Friday”, available at sontrak.com. Boolean operations can be described using logic gates, truth tables or an equation.

Within a few minutes I had the following truth table, drawn from the input equation:

```
Y = (CLK ^ PHASE_A) ^ PHASE_B
```

A useful piece of software.
