1、在ISE中直接调用chipscope进行在线逻辑分析（3）点击NeXt之后，进入了捕获参数的设计界面，如图4所示。“捕获”的含义自然指的是要被捕捉、观测的数据了。这里的参数ISE一般情况下己经给黄能设置好了，所以不需要更改。宝ChiPSCOPePoCOreInSertermychiPSCOPe.cdcFi1eEditHe1pIHOoBDEVICE日ICONUO：I1AI1A(TriggerParametersCaptureParametersNetConnectionsCaptureSettingsCoreUti1izationDataDepth:4096Samp1es-TriggerPort
