1. A method of developing graphics hardware and software, comprising:

  • providing a model of a graphics system in which a class of commands has a corresponding abstract state machine representation that includes a set of state variables;

    performing semantic processing on said model to generate validation logic capable of utilizing a reduced memory space shadow memory storing state information for performing validation of said class of commands that is smaller in size than a full version of said set of state variables; and

    executing driver software issuing commands within said class of commands;

    wherein said validation logic utilizes said reduced memory space shadow memory to determine exceptions generated by said driver software, wherein said model is an object model in which the object has an abstract state machine representation defining object behavior and associated object state.
