587 : Ford Thunderbird Rearlights Controller - IEEE OpenSilicon Bootcamp
- Author: Juan Fernando Posso & Pierina Miraba
- Description: The circuit implements a sequential rear-light controller inspired by the Ford Thunderbird, using a 2-bit counter to generate timing states. A controller and decoders convert these states into progressive left and right light patterns based on the input signal.

How it works
The circuit uses a 2-bit counter to generate a repeating sequence of states that act as timing steps. A combinational controller routes this sequence to the left lights, right lights, both, or neither based on the blinker input, and the decoders transform each state into a progressive 3-bit pattern that creates the sequential lighting effect (similar to the Ford Thunderbird).
How to test
Apply reset (rst_n = 0) to initialize the counter. Release reset (rst_n = 1). Set blinker to each value (00, 01, 10, 11) and observe outputs: 00 → both outputs off 01 → left sequence active 10 → right sequence active 11 → both sequences active Run the simulation for several clock cycles and confirm the outputs follow the expected progression
