    • Methods and systems for evaluating checker quality of a verification environment are provided. In some embodiments, an overall sensitivity for the verification environment and an individual sensitivity for a respective checker are calculated. The overall sensitivity is a probability that a plurality of problematic design behaviors, which are propagated to a checker system including at least one checker, can be detected by the verification environment. The individual sensitivity is a probability that a plurality of problematic design behaviors, which are propagated to at least one specific probe among a plurality of probes of a design, can be detected by the checker corresponding to the specific probe. The overall checker sensitivity numbers can show the robustness of the check system. The individual checker sensitivity can guide the user which individual checker or checkers to improve.
    • 提供了用于评估验证环境的检查器质量的方法和系统。 在一些实施例中,计算验证环境的总体灵敏度和相应检查器的个体灵敏度。 总体灵敏度是通过验证环境可以检测到传播到包括至少一个检验器的检查系统的多个有问题的设计行为的概率。 个体敏感度是通过与特定探针对应的检查器可以检测到在设计的多个探针中传播到至少一个特定探针的多个有问题的设计行为的概率。 整体检查灵敏度数字可以显示检查系统的稳健性。 单独的检查灵敏度可以指导用户哪个单独的检查器或检查器改进。

    • A computer-based simulation process executes a checkpoint operation while simulating behavior of an electronic circuit by forking an active checkpoint process having the same state as the original simulation process. While simulation time for the simulation process continues to increase after executing the checkpoint operation, simulation time for the checkpoint process remains unchanged so that the checkpoint process remains in the state of the simulation at the simulation time it executed the checkpoint operation (the “checkpoint time”). When the checkpoint process subsequently receives a request to resume simulating the circuit, it forks a new simulation process that mimics the original simulation process as of checkpoint time, and the new simulation process then begins to advance its simulation time, thereby enabling it to re-simulate behavior of the electronic circuit previously simulated by the original simulation process starting from the checkpoint time.

    • A method of displaying an image of a window object, includes the steps of: (a) checking a display mode of a display module, and allocating a first section and a second section in a buffer if the resolution of the display mode is below a predetermined level; (b) outputting an original color value of a front image to the first section and the second section respectively, and producing a first view in the first section and a second view in the second section accordingly; (c) calculating an alpha value of the front image by means of the first view and the second view, and saving the alpha value to the first section; and (d) outputting the original color value and the alpha value to display an image of a windowless object.
    • 一种显示窗口对象的图像的方法包括以下步骤:(a)检查显示模块的显示模式,并且如果显示模式的分辨率低于一个,则将第一部分和第二部分分配在缓冲器中 预定水平; (b)分别向第一部分和第二部分输出正面图像的原始颜色值,并相应地产生第一部分中的第一视图和第二部分的第二视图; (c)通过第一视图和第二视图计算前图像的α值,并将α值保存到第一部分; 和(d)输出原始颜色值和α值以显示无窗口对象的图像。
