List manipulation

Ali Bastami

Hi

I am quite new to Skill programming and would appreciate support on list manipulation.

Lets say that I have a list like this

MyList=list(list("a" "b" "c") list("d" "e" "f") list("g" "h" "i") ...):

(("a" "b" "c")
("d" "e" "f")
("g" "h" "i")

...
)

and I would like to go through each "line" of the list (a subset of "a" "b" "c" of elements).

if first element of the subset = "name" then

x=first element of the subset

y=second element of the subset

z=third element of the subset.

and loop through the list.

Thanks!

  • Hi,
    You can do something like:

    ;; Lisp style
    (foreach sublist MyList
      (when (equal "name" (car sublist))
        (destructuringBind (x y z) sublist
          (printf "x: %A y: %A z: %A\n" x y z)
          )))

    ;; C-style
    foreach( sublist MyList
      when( nth(0 sublist) == "name"
        let( (x y z)
          x = nth(0 sublist)
          y = nth(1 sublist)
          z = nth(2 sublist)
          printf("x: %A y: %A z: %A\n" x y z)
          )))

    Hope this helps,

    Cheers,

    Thank you for your quick respond, 

    I  think I need to develop my question a bit more, I am trying to retrieve the sos revision used in a cadence config view.
    I already have a skill script that creates a list of my included cells and views and I am trying to walk through the list and retrieve SOS rev for each cell included in the hierarchy.

    The following scripts retrieve the correct SOS revision stand alone:

    cv=dbOpenCellViewByType(mylib mycell myview)
    sosrev=SosGetRev(cv)

    but when I call this function in the loop the input parameters to the function are not updated for each sublist

    An example list would look like: 

    myList=list(
    list("Proj" "Proj_test_trx" "schematic")  ; sosrev=44
    list("Proj" "Proj_test_tx_lpm_core" "schematic") sosrev=14
    list("Proj" "Proj_test_trx" "symbol"); sosrev=44
    list("Proj" "Proj_test_trx" "schematic"); sosrev=28
    list("Proj" "Proj_test_switch_top" "symbol"); sosrev=32
    list("Proj" "Proj_test_switch_top" "schematic_Full_EM_Analysis_lga"); sosrev=14
    list("Proj" "Proj_test_switch_notch_switch" "symbol") ; sosrev=18
    list("Proj" "Proj_test_switch_notch_switch" "schematic"); sosrev=2
    list("Proj" "Proj_test_switch_notch_Cn" "symbol"); sosrev=19
    list("Proj" "Proj_test_switch_notch_Cn" "schematic_ideal"));sosrev=17

    foreach( sublist myList
    when( nth(0 sublist) == "Proj"
    let( (mylib mycell myview)
    mylib = nth(0 sublist)
    mycell = nth(1 sublist)
    myview = nth(2 sublist)
    cv=dbOpenCellViewByType(mylib mycell myview)
    sosrev=SosGetRev(cv)
    printf("mylib: %A mycell: %A myview: %A sosRev: %A\n" mylib mycell myview sosrev)
    )))

    each individual cell have different revision number. But for some reason,

    cv=dbOpenCellViewByType(mylib mycell myview)
    sosrev=SosGetRev(cv)

    only responds to the first subset of the list.

    and the results will be:

    mylib: "Proj" mycell: "Proj_test_trx" myview: "schematic" sosRev: "44"
    mylib: "Proj" mycell: "Proj_test_tx_lpm_core" myview: "schematic" sosRev: "44"
    mylib: "Proj" mycell: "Proj_test_trx" myview: "symbol" sosRev: "44"
    mylib: "Proj" mycell: "Proj_test_trx" myview: "schematic" sosRev: "44"
    mylib: "Proj" mycell: "Proj_test_switch_top" myview: "symbol" sosRev: "44"
    mylib: "Proj" mycell: "Proj_test_switch_top" myview: "schematic_Full_EM_Analysis_lga" sosRev: "44"
    mylib: "Proj" mycell: "Proj_test_switch_notch_switch" myview: "symbol" sosRev: "44"
    mylib: "Proj" mycell: "Proj_test_switch_notch_switch" myview: "schematic" sosRev: "44"
    mylib: "Proj" mycell: "Proj_test_switch_notch_Cn" myview: "symbol" sosRev: "44"
    mylib: "Proj" mycell: "Proj_test_switch_notch_Cn" myview: "schematic_ideal" sosRev: "44"

    any ide why the parameters are not updated when dbOpenCellViewByType is called?

    Hi Ali,

    The problem is not with the dbOpenCellViewByType, since I constructed the same cellViews that you had in your example, and altered the code slightly to just do sosRev=cv since I don't have ClioSoft. (now Keysight) SOS:

    mylib: "Proj" mycell: "Proj_test_trx" myview: "schematic" sosRev: db:0x2803d61a
    mylib: "Proj" mycell: "Proj_test_tx_lpm_core" myview: "schematic" sosRev: db:0x2803d41a
    mylib: "Proj" mycell: "Proj_test_trx" myview: "symbol" sosRev: db:0x2803d31a
    mylib: "Proj" mycell: "Proj_test_trx" myview: "schematic" sosRev: db:0x2803d61a
    mylib: "Proj" mycell: "Proj_test_switch_top" myview: "symbol" sosRev: db:0x2803d21a
    mylib: "Proj" mycell: "Proj_test_switch_top" myview: "schematic_Full_EM_Analysis_lga" sosRev: db:0x2803d11a
    mylib: "Proj" mycell: "Proj_test_switch_notch_switch" myview: "symbol" sosRev: db:0x2803d01a
    mylib: "Proj" mycell: "Proj_test_switch_notch_switch" myview: "schematic" sosRev: db:0x2803cf1a
    mylib: "Proj" mycell: "Proj_test_switch_notch_Cn" myview: "symbol" sosRev: db:0x2803ce1a
    mylib: "Proj" mycell: "Proj_test_switch_notch_Cn" myview: "schematic_ideal" sosRev: db:0x2803cd1a

    as you can see, the cellVIew ids are different for every row. Or if I did:

    sosRev=list(cv~>cellName cv~>viewName) 

    and ran again:

    mylib: "Proj" mycell: "Proj_test_trx" myview: "schematic" sosRev: ("Proj_test_trx" "schematic")
    mylib: "Proj" mycell: "Proj_test_tx_lpm_core" myview: "schematic" sosRev: ("Proj_test_tx_lpm_core" "schematic")
    mylib: "Proj" mycell: "Proj_test_trx" myview: "symbol" sosRev: ("Proj_test_trx" "symbol")
    mylib: "Proj" mycell: "Proj_test_trx" myview: "schematic" sosRev: ("Proj_test_trx" "schematic")
    mylib: "Proj" mycell: "Proj_test_switch_top" myview: "symbol" sosRev: ("Proj_test_switch_top" "symbol")
    mylib: "Proj" mycell: "Proj_test_switch_top" myview: "schematic_Full_EM_Analysis_lga" sosRev: ("Proj_test_switch_top" "schematic_Full_EM_Analysis_lga")
    mylib: "Proj" mycell: "Proj_test_switch_notch_switch" myview: "symbol" sosRev: ("Proj_test_switch_notch_switch" "symbol")
    mylib: "Proj" mycell: "Proj_test_switch_notch_switch" myview: "schematic" sosRev: ("Proj_test_switch_notch_switch" "schematic")
    mylib: "Proj" mycell: "Proj_test_switch_notch_Cn" myview: "symbol" sosRev: ("Proj_test_switch_notch_Cn" "symbol")
    mylib: "Proj" mycell: "Proj_test_switch_notch_Cn" myview: "schematic_ideal" sosRev: ("Proj_test_switch_notch_Cn" "schematic_ideal")

    Perhaps you need to speak to ClioSoft support and find out if there's a problem with their function?
