Customisable Design - 7-Seg

This circuit will output a string of characters (’tiny tapeout’) to the 7-segment display.

The logic to light the characters appears in the bottom half of the simulation window.

The top half of the simulation window implements a modulo-11 counter. In other words, the counter increments up to 11 then resets. This counter is used to determine which character we should output to the 7-segment display.

The truth table for the design can be found in the Design Spreadsheet
