有谁用过DSP Builder的HIL模块的？

Warning: Sample time mismatch. Sample time ([0, 0]) of signal at output port 1 of
'FreqSweep/Ramp/Output' does not match the sample time (1) specified for this signal by
'FreqSweep/Signal Specification'.  Consider using a Rate Transition block to resolve the
mismatch.  To turn off reporting of this condition, change the value of the 'Enforce
sample times specified by Signal Specification blocks' parameter in the Sample Time group
of the Diagnostics pane of the Configuration Parameters dialog box to 'none'.

'E:\Program' 不是内部或外部命令，也不是可运行的程序
或批处理文件。
Error using alt_dspbuilder_Hil_GetTopLevelIo (line 50)
Loading project FreqSweep failed.
         Check the Matlab Command Window for error messages.

这是怎么回事？我用的是ALTERA公司的示例  但在HIL设置添加工程是  出现错误提示
ERROR:  Loading project FreqSweep failed.          Check the Matlab Command Window for error messages.          Refer to the HIL Trouble Shooting section of the Reference Manual for further details.
然后MATLAB的COMMON窗口出现上面的提示信息
