DYNAMICALLY MODIFIABLE COMPONENT MODEL

To emulate a hardware component of a target hardware system including a plurality of hardware components, a component model of the hardware component is built, where the component model includes a register interface through which a host application provides inputs to and reads outputs from the component model, one or more parameter registers that hold values of state variables of the component model, and a state machine that models behavior of the hardware component without explicitly emulating logic implemented in the hardware component. During modeling of the hardware component utilizing the component model the component model is dynamically modified other than by modifying values of the state variables.
