Abstract:
Disclosed herein are representative embodiments of methods, systems, and apparatus that can used to control real-time events (e.g., the real-time clock) during the design, simulation, or verification of an embedded system. In one exemplary embodiment disclosed herein, for example, a real-time clock signal is generated and tasks defined by an embedded software application are triggered with the real-time clock signal. In this embodiment, the embedded software application is executed by an embedded processor with a real-time operating system (“RTOS”), and the real-time clock signal is controllable independent of a processor clock signal driving the embedded processor in a manner that allows the real-time clock to have a different time base than the processor clock.
