    Date of Patent: January 5, 2016
    Assignee: Lattice Semiconductor Corporation
    Inventors: Chinsong Sul, Hyukyong Kwon, Andy Ng
  • Patent number: 8841974
    Abstract: A method and apparatus is disclosed herein for testing of multiple ring oscillators. In one embodiment, the apparatus comprises at least one ring oscillator structure having a ring oscillator having an inverter chain with an odd number of inverters connected back-to-back and operable to produce an oscillatory output, and a test structure coupled to provide either an observability chain input or a test input to the ring oscillator and to receive the oscillatory output as a feedback from the ring oscillator.
