VHDL代码不在板上工作但在仿真上工作

我正在使用vhdl开发一个项目来配置fpga board spartan 3E。我要做的是一个天才之谜,在我的主要代码中有一个状态机来控制逻辑。

当我使用xilinx模拟器模拟代码时,一切运行良好但是当我将.bit文件运行到FPGA板时,会发生的是序列的第一个LED开启然后关闭,这应该发生但是当我单击右键,它停止工作,下一个序列永远不会显示。 当然还有一个问题是使按钮失效,这就是我使用计数器防止复制品破坏系统的原因。

我正在努力使用此代码,但这个问题并没有消失,也许我做错了什么我不知道或者我没有做我应该做的事情。

这是我的主要代码,它是状态机和计数器的时钟进程。

Flag_conte = starts ou blocks the counter
Flag_estou_contando = 1=counting, 0= not counting, 3= just finished count.
BCD = board buttons IN
LEDs = corresponds to 4 leds that will show the sequence in the game

if i wasnt clear, please let me know i will try to explain better, if anyone could help i would be very greatful, thank you for your time.

你应该试试post place&amp;路线模拟验证最新情况: http://www.xilinx.com/support/documentation/sw_manuals/xilinx11/pp_p_process_simulate_post_place.htm

使用某些家庭设备,您可以使用chipcope技术进行调试:

抱歉我的英文。
