Method and apparatus for evaluating programming used by a programmable processor device in a disc drive to carry out servo control of a head with respect to a rotatable disc. The programming is first generated as a series of instructions executable by the programmable processor device. Processor emulation software is used to simulate execution of the instructions in a computer. A dynamic model of electrical and mechanical portions of the disc drive is generated using plant simulation software. A dynamic linking program is configured to synchronize and transfer data between the processor emulation software and the plant simulation software. All three programs are thereafter simultaneously executed in the computer to evaluate realtime operation of the programming.
