如何使EOS信号正常运行?

大家好,
我正在尝试使用由STARTUP_SPARTAN6实体生成的EOS信号来实现描述其中的解决方案。
我将FPGA配置为串行从机模式。
在我的设计中实例化STARTUP_SPARTAN6看起来像这样:
startup_spartan6_1:startup_spartan6端口映射(EOS => eos, - 在配置完成时启用所有时钟CLK =>'0',GSR =>'0',KEYCLEARB =>'0',GTS =>'0',
CFGMCLK => open,CFGCLK => open);
以上编译没有问题。
在行为模拟中(我使用的是ISim 13.4 nt64)我希望看到EOS信号变高,但它会永远处于未定义状态(VHDL'U'状态)。
如何使EOS信号正常运行?
最好的祝福,
亚当

Hi all,

I am trying to use EOS signal generated by STARTUP_SPARTAN6 entity to implement solution descrived in this answer record. I configure my FPGA in serial slave mode. The instantiation of STARTUP_SPARTAN6 in my desing looks like that:

startup_spartan6_1 : startup_spartan6
port map (
EOS => eos, -- enabling all the clocks when the configuration is finished
CLK => '0',
GSR => '0',
KEYCLEARB => '0',
GTS => '0',
CFGMCLK => open,
CFGCLK => open);

Above compiles without problems. In behavioral simulation (I am using ISim 13.4 nt64) I expect to see EOS signal to go high, but instead it stays in undefined state (VHDL 'U' state) forever. How can I make EOS signal to behave correctly?

Best regards,
Adam
