|  | # Fuzzer for the remaining INT PIPs | 
|  |  | 
|  | Run this fuzzer a few times until it produces an empty todo.txt file (`make run` will run this loop). | 
|  |  | 
|  | This fuzzer occationally fails (depending on some random variables). Just restart it if you encounter | 
|  | this issue. The script behind `make run` automatically handles errors by re-starting a run if an error | 
|  | occurs. | 
|  |  | 
|  | ### Solvability | 
|  |  | 
|  | Known issues: | 
|  | * INT.CTRL0: goes into CLB's SR. This cannot be routed through | 
|  |  | 
|  | Jenkins build 3 (78fa4bd5, success) for example solved the following types: | 
|  | * INT_L.EE4BEG0.LH12 | 
|  | * INT_L.FAN_ALT1.GFAN1 | 
|  | * INT_L.FAN_ALT4.BYP_BOUNCE_N3_3 | 
|  | * INT_L.LH0.EE4END3 | 
|  | * INT_L.LH0.LV_L9 | 
|  | * INT_L.LH0.SS6END3 | 
|  | * INT_L.LVB_L12.WW4END3 | 
|  | * INT_L.SW6BEG0.LV_L0 |
