The addition of PC to a Full Function Test System (FFTS) has made it possible to eliminate simulator-only test cases by allowing test cases designed for the real hardware to also be used in the simulated environment. The techniques of this disclosure connected the PC-driven testing with a simulated FFTS and I/O processor (IOP). To show the detail of this unique connection, it is first necessary to more completely define the I/O processor and the model of it. Very simply this I/O processor attaches to the I/O bus. This processor, in turn, attaches physical I/O devices such as hard disks and tape, but it is possible to consider these devices as a part of the IOP. When this "larger" IOP is considered, all input and output is via the bus, as in Fig. 1.
