.vhd小问题

fanqiongjian

use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
(E371) Can't find 'std_logic_arith' in library 'ieee' with path 'd:\program files\lib\ieee\work'.
请问各位大侠，怎么解决这个问题？

bravelu

能不能说明一下是在用什么软件的情况下遇到的问题？
软件的安装目录结构如何？

fanqiongjian

我用的是cypress公司的cpld芯片。软件是warp2！！我把它安装在D目录下，这会有问题吗？

xzffff

是不是library的路径没有设置好？

bravelu

能打开1164库却找不到arith？不太正常啊。可以看下lib目录下有没有arith相关的VHDL包。
另：cypress不是说要退出pld市场么，还有人在用他们的东西？

fanqiongjian

因为第一次做板子，原理图大部分参照了开发板的原理图，所以就用了cypress公司的cpld芯片（cy37032vp44－100jc）。现在遇到很多麻烦了！

fanqiongjian

arith相关的VHDL包是什么样的？可不可以给我发一份。还有关于STD_LOGIC_的VHDL包？？？谢谢！请帮帮忙！！

bravelu

我是在MAXPLUS的目录下copy来的，和这个一起的还有1164包，相信你的软件目录下也有，可能是没有设置好。

非常谢谢！！！！
