## Purpose
|
2019-10-24 22:51:47 +02:00
|
|
|
Trying to set SLICEM LUT DI1 inputs
|
|
|
|
|
These exist for LUTA, LUTB, and LUTC only
|
|
|
|
|
Can either be an external signal, another LUT's data input, or another LUT's carry
|
|
|
|
|
Note: mux input pattern is irregular

|
|
|
bit 00_00 ADI1MUX.AI
|
|
|
|
|
bit 00_20 BDI1MUX.BI
|
|
|
|
|
bit 01_43 BDI1MUX.CI
|

|
|
|
```
|
2019-10-24 22:51:47 +02:00
|
|
|
Additionally, test with unknown DI mux bits don't appear near NI bits
|
|
|
|
|
There is something strange going on
