电子书-RTL Design Style Guide for Verilog HDL540页A FF having a fixed input value is generated from the description in the upper portion of Example 2-21. In this case, ’0’ is output when the reset signal is asynchronously input, and ’1’ is output when the START signal rises. Therefore, the FF data input is fixed at the power supply, since the typical value ’1’ is output following the rise of the START signal. When FF input values are fixed, the fixed inputs become untestable and the fault detection rate drops. When implementing a scan design and converting to a scan FF, the scan may not be executed properl not be executed properly, so such descriptions , so such descriptions are not are not recommended. recommended.[1] As in the lower part of Example 2-21, be sure to construct a synchronous type of circuit and ensure that the clock signal is input to the clock pin of the FF. Other than the sample shown in Example 2-21, there are situations where for certain control signals, those that had been switched due to the conditions of an external input will no longer need to be switched, leaving only a FF. If logic exists in a lower level and a fixed value is input from an upper level, the input value of the FF may also end up being fixed as the result of optimization with logic synthesis tools. In a situation like this, while perhaps difficult to completely eliminate, the problem should be avoided as much as possible.

OpenGL是图形API,是图形硬件的软件接口。它规定了用户输入图形数据信息形式,确定了图形处理的流程,规定了每个图形处理流程处理所需的参数的方式。

最近一段时间除了学习Qt,翻译Qt文档之外,由于工作和兴趣的原因,开始着手看Qt OpenGL编程。在网上搜索了有关OpenGL的教程,发现NeHe的OpenGL教程的还很不错,作者是NeHe。上面有很多种语言的实现,但是没有Qt和Gtk的,所以我就想着手写这个Qt OpenGL教程,每课的内容和NeHe是一样的。另外,介绍NeHe的一个中文翻译站点CSDN-CKer翻译的NeHe的OpenGL教程,翻译人是CKer,在我学习这个教程的过程中,给了我很大的帮助。下面就是Qt OpenGL教程的内容:Qt OpenGL的准备工作因为本教程是从NelHe的OpenGL教程迁移过来的,代码变为Qt实现的。所以有的课程一时还没有实现成功,所以可能有些教程是跳跃的。因本人时间有限,所以难免有错误出现,如果您发现了这些错误,或者有什么建议,请来信指教,谢谢。
