  • Clock simulation device and methods thereof
    Patent number: 8645117
    Abstract: A pulse width of a simulated external system clock is set by determining a least common multiple of the frequency of selected internal clock signals relative to the frequency of the external system clock. The pulse width can be further adjusted based on the frequency of simulated external clocks. By setting the pulse width of the simulated external system clock based on the least common multiple value, the time required to complete the simulation can be reduced while ensuring proper operation of the simulated clock signals during the simulation.
    Type: Grant
    Filed: May 27, 2010
    Date of Patent: February 4, 2014
    Assignee: Freescale Semiconductor, Inc.
    Inventors: Qichao R. Yin, Jen-Tien Yen, Wai Chee Wong
