ABSTRACT:
A hard disk simulator that comprises a timing generator controller coupled to receive address, data and control signals; a timing generator for providing a pulse in response to signals received from the timing generator controller; and an address generator coupled to receive the control or index pulse and a programmable frequency clock to generate addresses for a hard disk simulator. The address generator includes an offset counter that generates values in response to the programmable frequency clock and the control pulse. The address generator also receives a base address that corresponds to a hard disk track. The offset counter values and the base address are combined to provide an address. The present invention also includes a method of simulating a hard disk including the step of adding an offset value to a base value to simulate rotational latency of the hard disk. The method further includes at least one of the following steps: generating the offset value from a programmable frequency clock signal that corresponds to at least two hard disk zones; resetting the offset value in response to a pulse that corresponds to a hard disk index signal; and providing base values that each correspond to respective hard disk tracks.
