用modelsim需要怎么设置？？ modelsim, 设置

用ISE编辑好文件后，用Modelsim仿真出现以上信息？是modelsim 的设置问题吗？

我直接在ISE中用行为仿真，然后激活modelsim,以上信息是在modelsim中出现的。尤其是Module 'compare' does not have a `timescale directive in effect, but previous modules do.
奇怪，我已经在仿真文件中设置了`timescale ,怎么有问题？

前面的ERROR应该是库的问题，但是Module 'compare' does not have a `timescale directive in effect, but previous modules do这有点奇怪了，我程序写了.timescale

我也碰到过类似的问题,当时我试了好多简单的程序,都是你说的同一个问题,大概以前装的是试用的modelsim,后来换了一个modelsim,呵呵,现在ok了
