  • Method and apparatus for generating instructions for use in testing a microprocessor
    Patent number: 5646949
    Abstract: An apparatus and method for generating pseudo-random test instructions for testing a microprocessor begins by providing an array of list structures (502 through 508). Each list structure (502 through 508) contains a list of instructions, a discipline field (34), a pick field (42) and a biasing field (36). A random list of instructions is created by using a list selection discipline field to determine which list (502 through 508) is selected. The discipline field in the particular list (502 through 508) is then used to determine a manner in which instructions are selected from a list of instructions contained within the list structure. The pick field indicates how many instructions are to be selected from each selected list structure using a method determined via the discipline field.
