Start with Getting started
with *Digital Works* (Includes download
instructions.)

Links with the symbol are Digital Works binary files.

The *Explain* links connect to descriptions and
explanations of each circuit where they appear. The
*Exercise* links suggest exercises you can perform using
variations of the circuits.

- Circuit from
*Designing Combinational Circuits*handout. *Designing Combinational Circuits*example with sequence generators. Explain.- "Unwired" combinational circuit; a quick start for your own designs.
- Arithmetic-Logic Unit from Chapter 3 of Tanenbaum
- Simplified Arithmetic-Logic Unit from Chapter 3 of Tanenbaum This one omits the "extra" control inputs.
- Three-input odd function similar to Figure 3-2 in Mano & Kime. This one has interactive inputs to allow empirical verification that the circuit indeed computes the "odd" function.
- Three-input odd function template Same as above, but with "pins" instead of inputs and LEDs. You will need this circuit in order to use the next one.
- Seven-bit parity generator This circuit uses three instances of "3oddt.dwm" to generate an even parity bit for a seven-bit data word. This is the same idea as Mano & Kime's Figure 3-2 (b except that there are seven bits instead of nine. The exercise gives you an opportunity to use nine bits. Exercise.
- Binary adder as shown in M&K Figure 3-5 Interactive inputs for empirical verification.
- Binary adder template Binary adder arranged as a template for use in the circuit below.
- Binary adder with sequenced input. Produces a timing chart similar to M&K Figure 3-7. Explain.
