请问ocean仿真rcosc如何直接输出频率值

whb610

回复 10# cyl


   .。。。。。。。。。。。。   analysis(`tran ?stop "20u"  ?outputstart "5u" )
   temp( T )
   run()
   selectResult(`tran)
   freq = frequency(v("/vout" ?result "tran-tran"))
   plot( freq ?expr `( "freq" ) )

还是有问题，提示：wave1938 is not a waveform object that can be displayed and will be DELETED automatically,我在ADE界面下直接仿真也不会直接打印频率值，而是在ADE界面的outputs一栏中写入相应的freq值，请帮忙看一下怎么修改，谢谢

freq = frequency(v("/vout" ?result "tran-tran"))可以改成freq = frequency(VT("/vout"))
如果只跑一个瞬态，结果是ADE下面的一个数值；
如果跑参数扫描，结果是一幅图；

   改成freq =frequency(VT("/vout"))，并设定只对mos参数扫描，共输出5个结果，仿真完成后依然没有频率值的输出，五次仿真每次完成后都提示：wave1938 is not a waveformobject that can be displayed and will be DELETED automatically rcosc.rar (900 Bytes, 下载次数: 15 )

   格式不是很好，看起来费劲，你全选拷贝到写字板里，就很方便了

    我觉得是这样哈：你用了for循环，每次循环开始时都会把上次循环的结果删掉，所以结果从来都只是一个点，而不是一个阵列，无法plot；
你可以这样改改：在脚本的第一行打开一个port:
fp0=outfile("~/freq.txt")

把原来的plot语句换成fprintf语句：
fprintf(fp0 " %.3f\n“ freq)

你试试吧。
