    Abstract:The Achilles heel of classic analog computers was the
    complex, error prone, and time consuming process of programming.
    This typically involved manually patching hundreds or even
    thousands of connections between individual computing elements as
    well as setting many precision 10-turn potentiometers manually,
    often taking hours, or even days. Albeit being simplified by
    means of removable patch panels, switching from one program to
    another still was time consuming and thus expensive. With digital
    computers about to hit physical boundaries with respect to energy
    consumption, clock frequency, and integration density, analog
    computers have gained a lot of interest as co-processors for
    certain application areas in recent years. This requires some
    means for automatic reconfiguration of these systems under
    control of an attached digital computer. The following sections
    give an overview of classic and modern approaches towards such
    autopatch systems.
