ADDR CODER

A1 A2 A3 A4 A5 A6 A7 A8 B1 GND
B2 B3 B4 B5 B6 B7 B8 CS1 CS2 VCC

/CS1=/A1*B1+A1*/B1+/A2*B2+A2*/B2+/A3*B3+A3*/B3+/A4*B4+A4*/B4+/A5*B5+A5*/B5+/A6*B6+A6*/B6+/A7*B7+A7*/B7+/A8*B8+A8*/B8

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？

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~~~
