An architectural definition of an instruction set is parsed to identify distinct program instructions therein. These distinct program instructions are associated with operand defining data specifying the variables they require. A complete set of such distinct program instructions and their associated operand defining data is generated for the instruction set architecture and used to automatically generate instruction-generating code in respect of each of those distinct program instructions. The instruction-generating code can include an instruction constructor, an instruction mutator and an instruction encoder. The instruction-generating code which is automatically produced may be used by genetic algorithm techniques to develop test programs exploring a wide range of functional state of a data processing system under test. The architectural definition can also be parsed to identify a set of architectural state which may be reached excluding unreachable architectural points and unpredictable architectural points.
A method of automatically generating test program instructions for a data processing apparatus from an architectural definition of at least one instruction set of said data processing apparatus, said method comprising:
Apparatus for processing data operable to automatically generate test program instructions for a data processing apparatus from an architectural definition of at least one instruction set of said data processing apparatus, said apparatus comprising logic operable to perform the steps of:
