摘要
A method and apparatus for mapping an electronic device. The electronic device is loaded into a test fixture, which may be an automated test equipment (ATE). A laser beam is stepped across locations of interest. At each location of interest a minimum voltage and/or maximum frequency are computed. A contour map of the changes in minimum voltage and maximum frequency across a field of view of the electronic device is generated. Additional embodiments provide signaling a laser scan module during the rising edge of a synchronization pulse to indicate that minimum voltage (Vmin) and maximum frequency (Fmax) specification search data is provided to a laser voltage probe. A Vmin/Fmax module compares the specification search data with the data read from the laser voltage probe and computes a parameter shift value. The laser beam is moved to another location when the falling edge of the synchronization pulse occurs.
