ocean script - data print to file

jugemu1234

Hi,

I am very new to SKILL or ocean script . I have problems with following script. Firstly I created this ocean.ocn by ADE>Session>Save ocean script... Then added some lines to output data to file. However it ends up outputing error after successful simulation but I do not know what is wrong with this then tried to figure out by myself but couldnt.

I am sure this would be easy thing to do for some people. Hope someone help me out at the earliest oppotunity.

Thanks in advance.

out = outfile("results.txt" "a")
run()

results()
selectResults('tran)
outputs()
ocnPrint(?output out frequency(clip(VT("/net019"),1u,1.1u)) )

close(out)

  •  Hi,

    Thanks for your reply. 

    I wrote codes as you mentioned but I got weird results with following codes.

    PM= getData("phaseMargin" ?result "stb_margin")
    DCgain= value(db(mag(getData("loopGain" ?result "stb"))),0,?histoDisplay nil ,?noOfHistoBins 1 )
    UGF= getData("phaseMarginFreq" ?result "stb_margin")

    Outpus were like followings individually.

    nan       -49.6481            nan

    I have no idea what "nan" means to say and how to make it work properly.

    Maybe you can help me again.

     Thanks,
