标题: [问题]VHDL state machine 程式错误
时间: Mon Jun 18 17:26:22 2007
不知道是我步骤错误还是怎样
我按照上课抄的程式打上→开新档案夹→把ieee复制进去→然後再储存我打的程式xx.hdl
接下来compile我刚打的那个程式
出现讯息如下
# ** Error: (vcom-19) Failed to access library 'work' at "work".
# No such file or directory. (errno = ENOENT)
不知道是我抄错还是老师写错，请各位大大帮忙指正，谢谢..
还有...若是要模拟动作，请问该如何模拟
