(2)语言设计的捷径 我偶尔到 HDL 语言论坛去看看,看到很多人对语言的学习感到困难,其实语言的学习并不困难, 其捷径是什么,答案:先用原理图设计,尤其是一些基本的逻辑功能单元。分频计数,开关,串并、 并串等等。从某种角度来说语言的本质是原理图设计,如果您脑袋里想的原理图,手指在键盘上敲 出来的是语言,你可以不用担心代码可综合性。其实我学习语言是今两年的事情,我只看两三天 Verilog 语言语法,然后看看基本逻辑单元的表示方法和例子,就可以用 Verilog 进行设计了,当然会 在设计过程中碰到一些语法表示的困难,翻翻书就可以了。 当然,不是语言不重要,功能的实现也需要语言准确的表达,例如 case 语句如何避免 LATCH。 (3)有关仿真 我曾经有一个做 FPGA 的同事,每当设计完一个功能模块,就看到用 MODELSIM 仿真好几天, 一个设计下来,仿真耗用他很多时间,为什么会这样,原因有两个:基本原因是:功能架构或者说思 路没有想好,在那里凑,第二个原因是因为写代码的时候他脑袋里没有形成时序图。如果这两方面 都想好,仿真的工作量会大大减少的。 在设计和仿真过程时,多想一想被处理的与其他信号的时序关系,这对你的设计能力大有益处。 我刚开始 FPGA 设计时,一个简单的计数器都要仿真半天,别说一个功能模块了,那个阶段设 计是靠仿真才能设计出来的(汗,数字电路没有学好)。但随着设计的增多,水平的提高,仿真用的 时间越来越少了,为什么?因为当你的脑袋里有时序图时,仿真回归了它真正的本意,只不过验证 你(脑袋里的时序)设计是否正确的一个工具。

Linux Shell Scripting Cookbook - Third Edition by Clif Flynt English | 29 May 2017 | ASIN: B01N80F75Z | 552 Pages | AZW3 | 1.36 MB Do amazing things with the shell About This Book Become an expert in creating powerful shell scripts and explore the full possibilities of the shell Automate any administrative task you could imagine, with shell scripts Packed with easy-to-follow recipes on new features on Linux, particularly, Debian-based, to help you accomplish even the most complex tasks with ease Who This Book Is For If you are a beginner or an intermediate Linux user who wants to master the skill of quickly writing scripts and automate tasks without reading the entire man pages, then this book is for you. You can start writing scripts and one-liners by simply looking at the relevant recipe and its descriptions without any working knowledge of shell scripting or Linux. Intermediate / advanced users, system administrators / developers, and programmers can use this book as a reference when they face problems while coding. What You Will Learn Interact with websites via scripts Write shell scripts to mine and process data from the Web Automate system backups and other repetitive tasks with crontab Create, compress, and encrypt archives of your critical data. Configure and monitor Ethernet and wireless networks Monitor and log network and system activity Tune your system for optimal performance Improve your system's security Identify resource hogs and network bottlenecks Extract audio from video files Create web photo albums Use git or fossil to manage revision control and interact with FOSS projects Create and maintain Linux containers and Virtual Machines Run a private Cloud server In Detail The shell is the most powerful tool your computer provides. Despite having it at their fingertips, many users are unaware of how much the shell can accomplish. Using the shell, you can generate databases and web pages from sets of files, automate monotonous admin tasks suc
