Migen Clock Domains Summary

Terminology

• Declaring a clock domain:
  • self.clock_domains.cd_mycd = ClockDomain()
• Referencing a clock domain:
  • self.sync.mycd += []
  • ClockSignal("mycd")
• Requesting an I/O signal:
• platform.request("clk12")

# 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

Synergy on Linux - It's great when it works, but it's also a pain because most guides are intended for Ubuntu 18, which is absolutely useless now. Here is how I was able to setup Synergy at login on a Pop_OS 22.04, but should ALSO work for ANY distribution using GDM3 as it's login manager (i.e Fedora and/or Ubuntu).

Step 1

Install synergy. Make sure that synergyc is installed first (included in deb or rpm)

Step 2
