Description: This circuit will output a string of characters (’tiny tapeout’) to the 7-segment display.
Wokwi project
Clock: 1 Hz
External hardware:
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: https://docs.google.com/spreadsheets/d/1-h9pBYtuxv6su2EC8qBc6nX_JqHXks6Gx5nmHFQh_30/edit
