    • Virtual Real Time (VRT) provides high fidelity timing for software simulator environment running in a workstation. VRT is scalable and controllable. VRT provides flight and simulation software synchronization mechanism. This feature guarantees that the causality effect between flight software when interacting with simulated devices is the same as running flight software in a real test-bed environment. VRT provides high-resolution timing, which facilitates monitoring and detection of timing related faults while running the simulation software system on a workstation. VRT is modularized, such that the switchover from virtual clock to real clock is a trivial task. Running the system on a workstation using VRT behaves exactly like a real system, with the added benefits of user controllable features such as start, stop, monitor and time-scale. Performance of systems running with VRT is generally very good, equal to or better than the hardware, as the software runs natively on a faster workstation.
    • 虚拟实时(VRT)为在工作站中运行的软件模拟器环境提供高保真时序。 VRT是可扩展和可控的。 VRT提供飞行和仿真软件同步机制。 此功能保证飞行软件与仿真设备交互时的因果关系效应与在实际测试台环境中运行飞行软件相同。 VRT提供高分辨率时序,便于在工作站上运行仿真软件系统时监视和检测与时序相关的故障。 VRT是模块化的,使得从虚拟时钟到实时时钟的切换是一个微不足道的任务。 使用VRT在工作站上运行系统的行为与实际系统完全相同,具有用户可控功能(如启动,停止,监视和时间尺度)的附加优势。 使用VRT运行的系统的性能通常非常好,等于或优于硬件,因为软件在较快的工作站上本机运行。
