CDF data structure 'flattened'

tailsnaf

 

I have been writing some skill code to extract information from a cell's cdf - but I see a mismatch between the docs and the way some information is stored in the skill code - it seems the simInfo part has all of it's data 'flattened' into a string, and I cannot access the parameters of simInfo.
 I am using IC 6.1.5-65b
So If I do the following, on the cdf of the vpulse component from analogLib I get:
cdf~>?
(buttonFieldWidth doneProc fieldHeight fieldWidth formInitProc
    id parameters promptWidth simModels type
    paramLabelSet opPointLabelSet opPointLabelSet simInfo paramEvaluate
    paramSimType paramDisplayMode netNameType termSimType termDisplayMode
    instNameType instDisplayMode
)
 
When I look into simInfo, I get a flattened view - as when I do:
cdf~>?simInfo~>? 
I get an error:
*Error* get/getq: first arg must be either symbol, list, defstruct or user type - ""
 
So instead if I just get the value of simInfo, all the information is there as a 'string'
cdf~>simInfo
(nil auLvs (nil propMapping nil namePrefix "") hspiceD (nil netlistProcedure hspiceDCompPrim_vpulse instParameters dc(acm acp v1 v2 td
    tr tf pw per
)
componentName vsrc termOrder (PLUS MINUS) propMapping
(nil) namePrefix "V" source t
termMapping (nil PLUS "" MINUS "(FUNCTION minus(root(\"PLUS\")))") noPortDelimiter t
)
...
...
...
) otherParameters (fundname noisefile FNpairs F1 N1
    F2 N2 F3 N3 F4
    N4 F5 N5 F6 N6
    F7 N7 F8 N8 F9
    N9 F10 N10
)
)
)
 
Is there a way to 'fix' the data structure format, so I cann access the sub-values of simInfo, like:
cdf~>simInfo~>termMapping 
Thanks for any help.

  • Actually, I have a quick follow-up.

     If I have a variable called term - set as follows:

    term = "PLUS"

    And I want to read the term-mapping from the CDF of this - by doing:

    cdf->simInfo->spectre->termMapping->PLUS

    it returns:

    \:p

     Which is fine - however if I want to use the variable 'term' - is there a way I can do this directly - or do I have to use sprintf to build the 'access command', and then evalstring to evaluate it, like:

    sprintf(s, "cdf->simInfo->spectre->termMapping->%s" term)

    evalstring(s)

    Thanks
