of claims 1 through 18, all the claims pending in this
application. The disclosed invention relates to the
simulation of a system having two continuous processes. The
two processes are simulated independently and interact with
each other by exchanging outputs. The outputs of each process
are used as inputs to the other process. Each process has a
different time step of simulation. A mechanical process has a
long time step whereas an electrical process has a short time
step. Regardless of the time steps and the rate of output
signal changes, the two simulation processes need to be
synchronized. In the claimed invention, one of the simulation
processes is provided with the capability to back track to a
previously simulated state when the simulation processes
become out-of-synch. The invention saves the state of the
first simulation process at the prescribed times. The

by said amendment are before us. There is a little confusion
in that Appellant attached as Appendix II only the amended
claims to the reply brief, leaving out the unamended claims.
Also, Appellant attached all of the claims as Appendix I to
the main brief, but they were the claims before the amendment.
Thus, Appendices I and II each partially cover the claims on
appeal.
