MxVDev allows you to choose the type of clock used to control simulations.
For real-time testing, MxVDev uses the RTClock, which corresponds as closely as possible to real time, sometimes called wall-clock time.
Accelerated time runs as fast as your computer can complete the necessary processing. For accelerated time, MxVDev uses the MxClock.
For example, a test case may include a transition in a stimulus signal at 10 seconds. The computer may be able to complete all previous events in much less than 10 seconds. At that point, the transition is transmitted to the Test Harness in simulated time.
To select the clock type, use the Execution tab in the Project Settings. You can also change it temporarily using the / button in the toolbar. When you choose a clock, you choose whether the Simulation time is real time or accelerated time.
