需要有关从Verilog开始和使用PLD进行设计的建议

你好，
我最开始使用Verilog和CPLD？
我对数字电子学基础知识，C ++等其他编程经验有很好的理解，并且有BSEE。
我没有机会在学校学习HDL课程而且我非常有兴趣学习HDL（我将从Verilog开始，因为我阅读比VHDL更容易）和设计CPLD。
我的雇主从事嵌入式设计业务，其设计主要基于PLD。
我购买了CoolRunner II套件并下载了Xilinx ISE软件套件。
关于Verilog的好书或介绍材料的任何建议？
CoolRunner是初学者的好入门套件吗？
由于价格便宜，我不介意买它。
此外，如果有任何文档具有专门针对CoolRunner II套件的示例，那将更好。
谢谢。

Hello,
Where shoudl I start with Verilog and CPLDs?
 
I have good understanding on digital electronics fundamentals, other programming experience such as C++, and have a BSEE. I didn't get a chance to take an HDL course in school and I am very interested in learning as much on HDL (I'll start with Verilog as I;ve read is easier than VHDL) and designing CPLDs. My employer is in the embedded desgin business and it's designs are primarly based on PLDs.
 
I purchased the CoolRunner II kit and downloaded the Xilinx ISE software suite. Any suggestions on a good book or introductory material for Verilog? It's the CoolRunner a good starter kit for a beginner? Since it was cheap I didn't mind buying it. Also, if there's any documentation that has examples specifically for the CoolRunner II kit that would be better.
 
Thanks.
 

我刚刚在亚马逊的Verilog CPLD书籍上搜索过，并没有出现真正针对CPLD的书籍。
我主要是一个VHDL人，但大约一年前我决定学习Verilog来理解一些现有的代码，并获得3本书。
对我帮助最大的是Chu的“Verilog示例的FPGA原型”。
它有很多例子。
我已经为FPGA和CPLD编写了代码，这可能听起来很简单但是一旦你瞄准了器件，很多代码开发都不会在FPGA和CPLD之间发生变化。
该工具与ISE一样，对您来说几乎是透明的。
使用CPLD，您可以更快地耗尽空间！
这引出了一个问题，如果Spartan XC3S50AN只有8.94美元（Digikey数量1），内置闪存并为您提供50K门，您为什么要使用CPLD？

以下为原文

I just did a search on Amazon books for Verilog CPLD and no books really specific to CPLDs came up.
 
I am mainly a VHDL person but about a year ago I decided that I needed to learn Verilog to understand some existing code, and got 3 books on it.  The one  that helped me the most is "FPGA Prototyping by Verilog Examples" by Chu.  It has lots of examples.
 
I have written code for both FPGAs and CPLDs, and this may sound simple-minded but once you target the device, a lot of your code development does not change between a FPGA and CPLD.  The tool, like ISE, makes it mostly transparent to you.  With a CPLD you just run out of space sooner !
 
Which gives rise to the question, if a Spartan XC3S50AN is only $8.94 (Digikey qty 1), has built-in flash and gives you 50K gates, why would you want to use a CPLD ?

我认为这本电子书是一个很好的起点 -  http://www.xilinx.com/publications/products/cpld/logic_handbook.pdf
它不是Verilog的介绍，但它是可编程设计方法的绝佳概述。
此外，它还向您展示了ISE中的语言模板，它为您提供了许多可以直接在代码中使用的Verilog或VHDL示例。
希望您的套件附带一些参考设计和教程，让您入门，然后您可以从那里扩展。
如果没有，您可能希望获得一个廉价的FPGA套件，这将极大地打开您的可编程机会。
这是一个便宜的选项 -  www.em.avnet.com/spartan3a-evl，如果你点击支持文件和附件，它确实包含了相当广泛的FPGA设计入门教程。

如果我不得不选择一本书，我喜欢道格拉斯史密斯的“HDL芯片设计”，但我不认为它已经印刷了。

以下为原文

I think this e-book is an excellent place to start -- http://www.xilinx.com/publications/products/cpld/logic_handbook.pdf
 
It is not an Intro to Verilog, but it's an excellent overview of the programmable design methodology.  Also, it exposes you to the Languague Templates in ISE, which gives you a number of Verilog or VHDL examples that you can use directly in your code. 
 
Hopefully your kit comes with some reference designs and tutorials that get you started, and then you can expand from there.  If not, you might want to get an inexpensive FPGA kit, which will vastly open up your programmable opportunities.  Here's an inexpensive option -- www.em.avnet.com/spartan3a-evl , and it does include a fairly extensive Introduction to FPGA Design tutorial if you click on the Support Files & Downloads link.
 
If I had to pick a book, I like "HDL Chip Design" by Douglas Smith, but I don't think it's in print anymore.
