Error encountered during pcell instantiation??

Messi
 Hai,

     

    This is the code i have written to read a file and then instantiate a pcell inside an already created pcell:

procedure(mypcell(ruleFile pcellInfo)

  let( (ruleFileTable purposeList mastercv inst )

  ruleFileTable  =  readFile( ruleFile )

;readFile is the function name for another procedure I created to read an file and drop its contents into a table

           foreach(line FileTable

           purposeList = caddr(line)

    ;the table has mainly four elements and I want the third element based on which instantiation has to be carried out

          unless(rexMatchp(pcellinfo purposeList)

           case(pcellinfo

             ("a"

         ;;To Create PCell for “a”

                    mastercv   = dbOpenCellViewByType("test" "pcell" "layout" "" "w")

                  ;mastercv is an already created pcell

                    inst           = dbCreateParamInst(

                                         "pcell" mastercv "a" list(0 0) "R0" 1

                                           list(

                                               list( "w"  "float" 0.5)

                                                )

                                                );dbCreateParamInst

                                         dbClose(mastercv)

                                      ); for case “a”

           ("b"

;;To Create PCell for "b"                   

                     mastercv   = dbOpenCellViewByType("test" "pcell" "layout" "" "w")

                     inst           =  dbCreateParamInst(

                                        "pcell" mastercv "b" list(0 0) "R0" 2

                                           list(

                                                list( "w"  "float" 0.5)

                                                list( "s"  "float" 0.25)

                                                )

                                            );dbCreateParamInst

                                          dbClose(mastercv)

                                          );case

                                   );for case  "b"               

                           );unless

        );foreach

    );let

);procedure

But i am generating errors while i run this code :

Can anyone look into and this find the error in it.....

Thanks,

  • Messi,

    This is getting rather beyond a bit of casual help; I'm getting close to having written the whole thing for you. Debugging code when you have not given all the pieces is rather hard. For example, I don't have parseFile, I don't have the latest version of your instPcell function  after the latest fixes. I might spot by inspection the errors, but without all the data, it is much harder and to be honest, I don't really have time given that I am doing this in my spare time (it's not part of my role at Cadence to answer things on this forum).

    If you want help, please attach (as an attachment) the entire code. That will at least avoid anyone having to invent the missing functions (which quite possibly are the reason for your problem).

    For example, I took the pieces you've given, and with some corrections to the arguments to dbCreateParamInst in instPcell so that the correct type of each pcell parameter were passed, I got the four cells created, each of which had some layout in. So the chances are that the problems are either in your latest version of instPcell or in parseFile (I just made a version of that up).

    If  you want to have the SPACE case reference the WIDTH case, I think you would need to store the rule information in such a way that you could look up the WIDTH rule for the same layer as the one you're on. This probably means multiple tables that you build when reading the file - one indexed by the rule name, and another which is a table of tables, indexed by the layer name, and then the rule type. Then you could do:

     ruleLookup["POLY"]["WIDTH"]

    or even:

     ruleLookup[nth(0 ruleTable[i])]["WIDTH"]

    to access the width rule for a layer when creating the SPACE instance.

    Anyway, I've already spent more time than I said I would on this, so back to the day job.

    Best Regards,

    Andrew.
