Random test generators (often abbreviated RTG or ISG[1] for Instruction Stream Generator or Instruction Sequence Generator[1]) are a type of computer software that is used in functional verification of microprocessors. Their primary use lies in providing input stimulus to a device under test.
In a simulation/testbench verification environment, the simulator processes input created by the RTG and coverage monitors may be used to verify that the generator is properly testing the design.[2]
Random test generators range in scope from simple scripts and parameterized macros that can be created in a matter of weeks to full featured systems requiring extensive software development. Random test generators are most often created by the designing organizations.
