136 : Tiny tapeout test gates

Author: Abdulrahman Alsabagh

Description: Just a simple test

Clock: 10000 Hz

How it works

AND, NAND and OR gates are connected to input a and b 16 flip flops are used to divide the clock spped with 2 ouptus, one at the 12th flop and one at the 16th.

How to test

Set the inputs and check the outputs match with the expected results:

| input a and b | output AND | output NAND | output OR |
|---------------|------------|-------------|-----------|
| 0 0           | 0          | 1           | 0         |
| 0 1           | 0          | 1           | 1         |
| 1 0           | 0          | 1           | 1         |
| 1 1           | 1          | 0           | 1         |

Set the clock to 10KHz and you should see the 5th output flashing quickly and the 4th output flashing slowly
