关于DSP仿真的一个棘手的问题。

我仿真DSP时老是出现以下错误：Trouble&nbsp;Halting&nbsp;Target&nbsp;CPU&nbsp;:&nbsp;Error&nbsp;0x00000020/-1151&nbsp;Error&nbsp;during:&nbsp;Execution,&nbsp;&nbsp;Processor&nbsp;communication&nbsp;timeout.&nbsp;It&nbsp;is&nbsp;recommended&nbsp;to&nbsp;RESET&nbsp;EMULATOR.&nbsp;This&nbsp;will&nbsp;disconnect&nbsp;each&nbsp;target,&nbsp;&nbsp;&nbsp;perform&nbsp;an&nbsp;emulation&nbsp;reset,&nbsp;and&nbsp;then&nbsp;reconnect&nbsp;each&nbsp;target.&nbsp;Power&nbsp;cycle&nbsp;the&nbsp;target&nbsp;board&nbsp;before&nbsp;continuing.<br />有时能连接成功，但几率特别小。请问各位高手，我应该怎么解决这个问题？实在着急呀！！！

或者是仿真芯片是旧片。
