ABSTRACT:
A design structure for systems for switching a displayed signal for a display between a plurality of signals are disclosed. In one embodiment, the design structure is embodied in a machine readable medium for designing, manufacturing, or testing an integrated circuit, and includes: a system for switching a displayed signal for a display between a plurality of signals, the system including: a microcontroller; a chooser for setting a primary signal from a plurality of program-variable signals; a monitor tuner coupled to the microcontroller for tuning the primary signal during switching of the displayed signal from the primary signal to a secondary signal; a detector coupled to the monitor tuner and the microcontroller for detecting a predetermined condition in the primary signal; and a selector coupled to the microcontroller for switching the displayed signal from the secondary signal to the primary signal upon occurrence of the predetermined condition.
