#### PHY Clock is 125MHz, on the PHY0 and PHY1 RXCLK inputs | |
#### 25MHz Clock on CLK25 | |
#### MDIO and RESET is shared between both PHYs | |
#### FLASH Clock, if needed in user logic, needs to be enabled trough USRMCLK | |
#### The INPUT_KEY_RC Pin is filtered with a RC combination | |
#### The GPIO Connectors are named after their pins on the connector. |

// This is a minimal example that shows the 4 main building-blocks needed to | |
// write concurrent/async coroutine code. | |
// | |
// 1. A coroutine type that lets users write their coroutine logic | |
// and call and co_await other coroutines that they write. | |
// This allows composition of async coroutine code. | |
// | |
// This example defines a basic `task<T>` type that fulfills this purpose. | |

# This is an nmigen delay line for ECP5 FPGAs using the open source toolchain. It strings together a series of | |
# manually placed carry chains into a "thermometer." It returns a signal that's (length) long that represents | |
# the chain "snapshotted" at the primary clock domain (using the flip flops colocated in the slice). | |
# | |
# This can be used in a Time to Digital Converter (i.e. to measure the time between to events) or in | |
# an ADC by comparing (with LVDS) a signal to a reference signal. | |
# | |
# Note that the bit precision (read: delay per carry element) varies as a function of temperature. On | |
# a LFE5U-25F-8MG285C, I've measure delay times of approximately 43ps on average. Due to assorted reasons, | |
# the delay time will vary between bits and due to variations in routing (even when manually places), you might |
