Abstract

Large-scale integration (LSI) read-only storage (ROS) modules store a large number of microinstructions accessed through a limited number of pins at fast rates. This presents problems during evaluation, e.g., difficulty in ideally generating an instruction level bug during diagnostic evaluation and inability to properly activate microcode error recovery routines.
