```
### Noise
```
SAA1099P noise generator as documented by Jepael
seed unknown, must be non-zero
18-bit Galois LFSR
Feedback polynomial = x^18 + x^11 + x^1
Period = 2^18-1 = 262143 bits
Verified to match recorded noise from my SAA1099P
```
### Octaves
Apparently that makes the noisegen to be clocked by the undivided octave clock, so lowest octave 0 is same as rate X. And each octave higher doubles the noise frequency.

# What is Tiny Tapeout?
TinyTapeout is an educational project that aims to make it easier and cheaper than ever to get your digital designs manufactured on a real chip.
To learn more and get started, visit https://tinytapeout.com.
## Verilog Projects
Edit the [info.yaml](https://github.com/rejunity/tt06-psg-saa1099/blob/master/info.yaml) and uncomment the `source_files` and `top_module` properties, and change the value of `language` to "Verilog". Add your Verilog files to the `src` folder, and list them in the `source_files` property.
The GitHub action will automatically build the ASIC files using [OpenLane](https://github.com/rejunity/tt06-psg-saa1099/blob/master/https://www.zerotoasiccourse.com/terminology/openlane/).
## How to enable the GitHub actions to build the ASIC files
Please see the instructions for:
