491 : IHP loopback tile with input skew measurement
- Author: Darryl Miles project from Eric Smith
- Description: Count up to 10, one second at a time.
- GitHub repository
- Clock: 10000000 Hz
How it works
This project is based on (https://github.com/ericsmi/tt05-loopback-with-skew) but for IHP30.
How to test
Clock the project and modiify the timing and examine FF capture reliabiliy.
External hardware
Skewable clock and data source.
