DESCRIPTION

这是我的程序，其实就是想实现8位数字比较器，像74ls518那样，因为74ls518买不着，所以才这样做，可以编译软件老是提示B6是输出定义，咋回事呀？

作者：CCWSD  2008-1-26 19:52:00

哈哈~~~GAL16V8有S,C,R三种定义

A1 A2 A3 A4 A5 A6 A7 A8 B1 GND

B2 B3 B4 B5 B6 B7 B8 CS1 CS2 VCC

A1~B1,B2只能做输入

选P16V8S:乘积项为8,只能做一般门电路

B6,B7为输出,B3,B4,B5,B8,CS1,CS2为输出输入

选P16V8C:乘积项为7,一般门电路可三态控制

B3,CS2为输出,B4,B5,B6,B7,B8,CS1为输出输入

选P16V8R:乘积项为8,寄存器型

B1为时钟输入,B2为使能,B3,B4,B5,B6,B7,B8,CS1为输出输入

倒塌了~~~求助也不把CS2的公式列出~~~

从管脚定义应该这样设置:

1.选P16V8S:

A1 A2 A3 A4 A5 A6 A7 A8 B1 GND

B2 B3 B4 B5 CS1 CS2 B6 B7 B8 VCC

2.选P16V8R:

A1 A2 A3 A4 A5 A6 A7 A8 B1 GND

B2 CS1 B3 B4 B5 B6 B7 B8 CS2 VCC

建议用ABEL或CUPL编程~~~

用Protel 99 SE自带的CUPL比较方便~~~

哈哈~~~腐败呀~~~菜农可怜的Cupl语言程序设计包

哈哈~~~再搭送楼主一个干坏事的工具~~~

搜索了74hc518没找到PDF文件...

由于GAL16V8系列只有8个乘积项,即乘积的和最多只能为8个,故'+'号只能出现7次.

所以电路必须接成P16V8S:

A1 A2 A3 A4 A5 A6 A7 A8 B1 GND

B2 B3 B4 B5 CS1 CS2 B6 B7 B8 VCC

程序应该写成:(你用的是FM软件???)

/CS1=/A1*B1+A1*/B1+/A2*B2+A2*/B2+/A3*B3+A3*/B3+/A4*B4+A4*/B4

/CS2=/A5*B5+A5*/B5+/A6*B6+A6*/B6+/A7*B7+A7*/B7+/A8*B8+A8*/B8

这样就输出了2个信号,即有1路相等即输出低电平信号.

如果只能测试1个有效信号,就必须再/CS=/CS1*/CS2.

由于CS1和CS2不能线与,故需再加门电路或在CS1和CS2的输出都加二极管IN4148后负极短接作为总输出/CS.

没用过FM软件,不知如何设置成'S型'.

对应的ABEL或CUPL语言写法:

!CS1 = A1 $ B1 注意: A1 $ B1 = (A1 异或 B1) = !A1 & B1 # A1 & !B1

# A2 $ B2

# A3 $ B3

# A4 $ B4;

!CS2 = A5 $ B5

# A6 $ B6

# A7 $ B7

# A8 $ B8;

帮人帮到底，送佛送到西，大好人。

嘿嘿，俺了蛮喜欢GAL芯片的。俺以前用ABEL4.0，后改用与Windows环境兼容的Lattic的Level环境做开发了。

作者：古道热肠  2008-1-27 11:03:00

LZ的问题和GAL没有关系，原因是数字逻辑没有学好。

作者：平常人  2008-1-27 11:08:00

哈哈~~~15年前玩的,现在练习练习看看忘了没~~~
作者：hotpower  2008-1-27 11:13:00

哈哈~~~平常人这次大错了~~~不了解GAL就定义不了管脚~~~
作者：hotpower  2008-1-27 11:15:00

惭愧

作者：平常人  2008-1-27 11:18:00

但是不知道我的设置还是啥地方有问题，总是生成不了。jed，郁闷
