Getting report() into a list

PhilipN

I want to get the operating point of a device into a list so I can fiddle about with it....but report() just writes to terminal....how do I get it into a list ?

I do not want to write it to a file.

For example

ocean> report(?param '("vds" "vgs"))


/MN2           
         vds    = 636.4m                   vgs    = 636.4m         
/MNbias        
         vds    = 636.4m                   vgs    = 636.4m  

But I want to put each device into a list with the vds, vgs etc

Thanks

  • Several ways:

    selectResult('dcOpInfo)
    stdobj@0x22fff920
    outputs()
    ("/I7/Q3" "/I7/Q2" "/I7/Q4" "/I7/Q0" "/I7/Q1"
    "/I7/C0" "/IPRB0" "/IPRB1" "/I7/IPRB0" "/I4"
    "/I7/M3" "/I7/M1" "/I7/M2" "/I7/M5" "/R1"
    "/R0" "/I7/R0" "/V2" "/I3/V2" "/I3/V0"
    )
    getData("/I7/M1")->??
    ("ids" -0.0001740973 "vgs" -2.231023 "vds"
    -5.967942 "vbs" 2.768977 "vth" -1.251779
    "vdsat" -0.8417994 "gm" 0.000353436 "gds"
    1.794715e-06 "gmbs" 4.537263e-05 "gameff" 0.4972989
    "betaeff" 0.0003707575 "cbd" 0.0 "cbs"
    0.0 "cgs" 5.84188e-13 "cgd" 2.432e-14
    "cgb" 4.857061e-14 "ron" 34279.34 "id"
    -0.0001740973 "ibulk" 2e-14 "pwr" 0.001039003
    "gmoverid" -2.030106 "isub" 0.0 "stress"
    0.0 "age" 0.0 "he_vdsat" 0.0
    "region" 2 "degradation" 0 "reversed"
    0 "type" 1
    )

    Or you could just do something like this:

    listOfInfo=foreach(mapcar device outputs(?type "mos2") ; change "mos2" to "bsim4" or whatever your models are called
      list(device pv(device "vgs") pv(device "vds"))
    )

    which produced:

    (("/I7/M3" -2.231284 -5.623888)
      ("/I7/M1" -2.231023 -5.967942)
      ("/I7/M2" 1.607134 1.263081)
      ("/I7/M5" 1.607134 1.607134)
    )

    In my simple test case.

  • Thanks Andrew - I did something to your last solution but what I did not know about was the "->??" operator - very nice.

    One quick thing - if I use report() I may get something like:

    Type : vcvs
    /Ebuffer
    model = vcvs
    i = -4.374z v = 636.4m pwr = -2.784z
    lx0 = 636.4m lx1 = -4.374z lx2 = 636.4m

    I want to get access to the "model" value (which here is "vcvs")...can't work out how to do this ?

  • The public function for doing this is:

    ocnGetInstancesModelName()
    (("/I7/Q3" "trpnp")
    ("/I7/Q2" "trpnp")
    ("/I7/Q4" "trpnp")
    ("/I7/Q0" "trnpn")
    ("/I7/Q1" "trnpn")
    ("/I7/C0" "capacitor")
    ("/I4" "isource")
    ("/I7/M3" "trpmos")
    ("/I7/M1" "trpmos")
    ("/I7/M2" "trnmos")
    ("/I7/M5" "trnmos")
    ("/R1" "resistor")
    ("/R0" "resistor")
    ("/I7/R0" "resistor")
    ("/V2" "vsource")
    ("/I3/V2" "vsource")
    ("/I3/V0" "vsource")
    )

    which can be given an optional argument which is either an instance name or list of instance names:

    ocnGetInstancesModelName("/I7/M2")
    ("/I7/M2" "trnmos")

    so you could do:

    cadr(ocnGetInstancesModelName("/I7/M2"))
    "trnmos"

    Regards,

    Andrew.
