Create symbol from schematic.

Serjik

Hi all,

1. I'm reading info from file.

2. The main part. Create library and schematic view. Insert mos device to schematic. After that i need to create symbol, but i stuck on this step. How can i do it ? Secondly how can i close the schematic editor window ?

Here is my cod:


x=infile("~/Desktop/Skill/input")
fscanf(x "%s %s %f %s %f %d %s %s %f %s %f %d" p w wp l lp mp n w1 wn l1 ln mn)
list(p wp lp mp n wn ln mn)

procedure( lib( name)
    dbCreateLib( name)
/*********************************/
    deNewCellView( name "p05" "schematic" "schematic" nil)
    cv=geGetEditCellView()
    dbCreateParamInstByMasterName(cv "Tech_lib" p "symbol" "i1" list(0 0) "R0" mp list(list("w_fing" "float" wp ) list("l" "float" lp)))
    schCheck(cv)
    dbSave(cv)
/*    hiCloseWindow( cv) */
/*********************************/
/*    deNewCellView( name "p05" "symbol" "schematicSymbol" nil)*/
schHiViewToView( name "p05" "schematic" "symbol" "schematicSymbol" )
hiFormDone(schSgForm)
);procedure

Best regards,

Sergey.

  • Hi Sergey,
    First of all, there’s no need to open the schematic in a window in the first place - you can do something like this:
    procedure( CreateLibSchSym(libName cellName tranName mp wp lp)
      let((cv)
        dbCreateLib( libName) 
        cv=dbOpenCellViewByType( libName cellName "schematic" "schematic” “a”) ; could use “w” instead of “a” if you want to erase any previous schematic
        dbCreateParamInstByMasterName(cv "Tech_lib" tranName "symbol" "i1" list(0 0) "R0" mp list(list("w_fing" "float" wp ) list("l" "float" lp)))
        schCheck(cv)
        dbSave(cv)
        schPinListToSymbol(libName cellName “symbol” schSchemToPinList(libName cellName “schematic”))
    );procedure
    Something like that. I’ve tried to make your function a bit less dependent upon global variables by passing them into the function as arguments. Of course, the above is not going to be particularly good as there are no pins on the schematic you’re generating, so the symbol would have no pins either.

  • Thank you Andrew, this is exactly what I need.
