With appropriate tool support, designers could perform execution or simulation and debugging on high-level system models to validate and verify system logic early on.

有了适当的工具支持，设计人员可以在高层的系统模型上进行执行或模拟，并调试，从而在早期确认并验证系统逻辑。

Running a business process in simulation mode is a great way to get early validation of a business process before investing in a solution to the wrong problem.

在仿真模型中运行一个业务过程，对于避免投入到错误的解决方案之中，尽早验证业务过程来说是一个很重要的方法。

In order to experience the T604, we took a look at three demos, including Timbuktu 2, which demonstrates elements like self shadowing and depth of field with OpenGL ES 3.0, Hauntheim, which gives us an early look at physics simulation and HDR lighting with OpenCL, and Enlighten, which rendered silky smooth real-time illumination.

An early example is the sugarscape simulation done in 1995 by Joshua Epstein and Robert Axtell, of the Brookings Institution.

Further, the government's nuclear regulatory body "did not require Tepco to take specific measures, such as additional construction, after they received simulation results from Tepco in 2008 and early in 2011 regarding the impact of tsunamis on their facilities".
