如何从ATLYS FPGA板开始？

我想编写一个LED闪光灯，我知道非常简单，但我无法弄清楚如何使用电路板上的LED ......
LED闪光灯的高低切换的美妙之处在于它会闪烁连接两个驱动极性的LED。
或按钮......
使用FPGA的按钮输入直接控制LED驱动输出。
按钮将变得非常简单匆忙。
使用MCU，事情变得更容易......
设计的第一个简单步骤是绘制其工作原理的流程图或逻辑图，然后实现流程图或图表的每个逻辑步骤。
另一个想法：访问这个网站为fpga初学者。
那里有很多很好的信息和例子。

以下为原文

I want to program a LED flasher, very simple I know, but I cannot figure out how to use the LEDs on the board...

The beauty of a LED flasher which toggles high and low is that it will flash LEDs wired up for either drive polarity.

or the Buttons...

Use the button inputs to the FPGA to directly control the LED drive outputs.  The buttons will become pretty simple in a hurry.

with MCUs things were much easier...

First simple step of design is to draw a flowchart or logic diagram of how it works, then implement each logic step of the flowchart or diagram.
 
Another idea:  visit this site for fpga beginners.  Lots of good information and example to be found there.

Bob, thanks, but here's my problem:
 
library IEEE;
use IEEE.STD_LOGIC_1164.ALL;


entity Simple is
    Port ( A : in  STD_LOGIC; Z : out  STD_LOGIC);
end Simple;

architecture arch_simple of Simple is

          else

How should I tell the FPGA that A means SW0 and Z means LED0 ?
 
The only info in the manual is that SW0=A10, LED0=U18...

在原理图中，似乎A10（SW0）被“称为”IO_L37N_GCLK12 ......

将A连接到SW0并将Z连接到LED0。

我可以很容易地把它拼出来......在Verilog中。
我可以阅读VHDL，但是我宁愿不发布我在人们依赖它时所写的VHDL代码是正确的。

Connect A to SW0 and connect Z to LED0.  Pinout details are in reference design .UCF file, and in board schematics.
 
I could spell it out for you quite easily... in Verilog.  I can read VHDL, but I'd rather not post VHDL code which I've written when people are depending on it to be correct.

In the meantime, suggest you spend your time learning VHDL.  This is a matter of a basic VHDL construct.  If this is a challenge to you, you have much to learn yet.  I wouldn't waste any time while you are waiting for help on this one item.
 
You can also learn quite a bit from reviewing example and reference designs which are written in VHDL.  Connecting signal pins really is a generic VHDL lesson, and surely is applicable universally to all FPGAs and FPGA families.

将用户约束文件（UCF）添加到项目中。
从Digilent站点上的Atlys参考UCF，复制您想要使用的LED和开关的定义，并将led（或其任何名称）重命名为Z，切换到AI通常包括整个参考UCF并注释掉
我没有使用的部件，如果存在不适用于您设计中任何内容的约束，您将会收到错误。



以下为原文

Add a user constraints file (UCF) to your project. From the Atlys reference UCF on the Digilent site, copy the definition for the LED and switch you want to use and rename the led<0> (or whatever it's called) to Z, and the switch to A.

I generally include the entire reference UCF and comment out the parts I'm not using, as you'll get errors if there are constraints that don't apply to anything in your design.

等待;

因为使用VHDL的人不是程序员，我们是硬件设计工程师。
你不编写VHDL程序。
您编写描述您要创建的硬件的VHDL。
这不是一个无关紧要的区别。
----------------------------是的，我这样做是为了谋生。

You'll wait forever, like this:
 
waitforever : process is
    wait;
end process waitforever;
 
because people who use VHDL are not programmers, we are hardware design engineers.
You do not write a VHDL program. You write VHDL that describes the hardware you wish to create.
 
This is not an irrelevant distinction.
----------------------------Yes, I do this for a living.

所以你想出来了吗？
我只是简单地看了你的HDL，但我没有看到任何错误。
至少不是在逻辑上，但那些“糟糕的同步描述”似乎偷偷摸摸我。
答案确实在UCF文件中。
当您使用uC时，您刚刚声明了一个可变LED，将其设置为1并期望LED继续运行吗？
您需要将该变量LED映射到GPIO。
所以你会有类似PORTA | = LED的东西吗？
这就是UCF文件的作用。
好吧，它实际上更像是将PORTA映射到芯片上的实际引脚。
我不记得语法，但它很简单，它在示例项目中（如果示例是正确的，Digilent总是在我购买的板上出错）。
在.ucf文件中查找包含您要使用的LED的行。
它将从NET开始，我记得那么多。
Digilent通常也会在电路板上写下这些信息，所以在LED和SW旁边你应该看到一个字母，后面跟着丝网印刷中的1或2个数字。
所以你会有类似的东西
NET LED LOC = X ##;
（大致）
NET SW0 LOC = X ##;
（大致）
现在，当您写入LED时，硬件知道该怎么做。
你似乎知道足够的VHDL来做到这一点。
我不知道为什么有人会给你带来很多困难。
第一张海报应该说“你需要一个UCF文件”并关闭线程lol。
提到了UCF文件，但随之而来的是太多kack ......
VHDL或Verilog都不会花费你超过一周的时间来学习。
我参加了一个我们使用Basys板的课程，在课程结束时我设计了一个8位处理器，一个VGA乒乓球游戏和一个2通道VGA示波器。
我不认为教授花了3个多小时教授VHDL。
就像有人在你不编写VHDL程序之前所说的那样，你用它来描述硬件，只要你明白你想用硬件做什么，只需要问谷歌如何在HDL中说出来。



以下为原文

So did you figure this out yet? I only briefly looked at your HDL but I didn't see any errors. At least not in the logic but those "bad synchrnous descriptions" seem to sneak up on me. The answer is indeed in the UCF file. When you were working with uC's did you just declare a variable LED, set it to 1 and expect the LED to go on? You needed to map that variable LED to your GPIO. So you would have something like PORTA |= LED right? That's what the UCF file does. Well kindof, it's actually more like mapping PORTA to the actual pins on the chip. I can't remember the syntax but it's simple and it's in the example project (provided the example is correct, Digilent has always made errors with the boards I have purchased). Look for the line in the.ucf file that has the LED you want to use. It will start with NET, I remember that much. Digilent also usually writes these right on the board so next to the LED and SW you should see a letter followed by 1 or 2 numbers in the silkscreen. So you will have something like
 
NET LED LOC=X##; (roughly)
NET SW0 LOC=X##; (roughly)
 
Now when you write to LED the hardware knows what to do. You seem to know enough VHDL to do this. I don't know why anyone what giving you a hard time about that. First poster should have said "you need a UCF file" and closed the thread lol. UCF file was mentioned but too much kack along with it...
 
Neither VHDL or Verilog should take you more than a week to learn. I took a class in which we used the Basys board and by the end of the class I had designed an 8 bit processor, a VGA pong game and a 2 channel VGA oscilliscope. I don't think the professor spent more than 3 hours teaching VHDL. Like someone said before you don't write a VHDL program, you use it to describe hardware and as long as you understand what you want to do with the hardware, it's just a matter of asking Google how to say it in HDL.

“无论是VHDL还是Verilog都不会花费你超过一周的时间来学习。”我必须是一个*非常*慢学习者，因为12年后我仍然学习更好的方法......但是，40小时的学习应该让大多数人学习
远远超过'新手'阶段。
------------------------------------------“如果它不起作用
模拟，它不会在板上工作。“



以下为原文

"Neither VHDL or Verilog should take you more than a week to learn."

I must be a *really* slow learner, as after 12 years I'm still learing better ways...
However, 40 hours of study should get most people well past the 'novice' stage.

------------------------------------------
"If it don't work in simulation, it won't work on the board."

然而，40个小时的学习应该让大多数人远远超过“新手”阶段。
如果是Verilog，可能需要80个小时。
VHDL的两倍（至少）。
