How to test
Align clocks, push them apart, look for bit errors
External hardware
A way to generate a clock

| # | Input | Output | Bidirectional |
|---|---|---|---|
| 0 | clk1 | stage3[0] | stage2[0] |
| 1 | stage3[1] | stage2[1] | |
| 2 | stage3[2] | stage2[2] | |
| 3 | stage3[3] | stage2[3] | |
| 4 | skew | stage1[0] | |
| 5 | stage1[1] | ||
