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")

Flags table for the operation: a - b

Flag Legend

• Z- Is the result zero?
• S- Is the top bit of the result set?
• C- Did a borrow not occur (see Subtraction on the 6502)?
  • For architectures with a true borrow flag, invert the C bit.
• V- Does the result of a - b fit within signed 16-bit range?
