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,

  • Hai,

       i understood i had to use atof since my values were in string.I was trying to tell that, in the first condition i gave the width as it is read from rules file.Now consider second condition when case is "SPACE" ie as per my code variable i will have rule no."R1B" (foreach loop i use so after carrying out "R1A" it will go to "R1B" or the next key),so in this second condition as per rule i can take value only as space which i feed inside list( "space" "float" nth(2 ruleTable[i])),but in the width section i want to give value as read from rule no. "R1A".

    ie   list( list( "w2" "float" "here value of POLY WIDTH as given in "R1A")

                list ("space" "float" nth(2 ruleTable[i]))

              )

    This was the confusion i had in my mind on how to get the value..

    I have run the code as per your suggestions and able to get cellviews with names of rule no.But the instantiation is not done properly i feel as each of them is empty.

    I have pasted the code by which i created my intial pcell...which i instanstiate in the cellviews named as rule numbers.

                       procedure(masterpcell(cv type)
                         let( ()
                          case(type
                             ("WIDTH"
                                 rodCreateRect(
                                         ?layer   list(layer1 "drawing")
                                         ?cvId    cv
                                         ?width   l1
                                         ?length  w1
                                         ?origin  list(0 0))
                             )
                          ("SPACE"
                                   lay1Id = rodCreateRect(
                                                   ?layer  list(layer1 "drawing")
                                                   ?cvId   cv
                                                   ?width  l1
                                                   ?length w1)
                                   lay2Id = rodCreateRect(
                                                     ?layer  list(layer2 "drawing")
                                                     ?cvId   cv
                                                     ?width  l2
                                                     ?length w2 )
                                    rodAlign(
                                                   ?alignObj lay1Id
                                                  ?alignHandle "lowerLeft"
                                                    ?refObj  lay2Id
                                                     ?refHandle "lowerLeft"
                                                      ?xSep -(space+l1) )
                               )
                    ("OVERLAP"
                            rodCreatePath(
                                         ?layer list(layer2 "drawing")
                                         ?width l2
                                          ?pts list(0.0:0.0 0.0:w2)
                                          ?encSubPath
                                                     list(
                                                            list(
                                                             ?layer   list(layer1 "drawing")
                                                              ?enclosure      l1
                                                              ?beginOffset   -overlap
                                                              ?endOffset     -overlap  )
                         )
                   );rodCreatePath
           )  
      );case
     );let
    );procedure

    ;;To Create PCell

                pcDefinePCell(
                       ;;Identify the target cellview.
                                 list(ddGetObj("lib1") "test" "layout"
                             ); end of list
        
                   ;;Declare parameter name-value pairs.
                              (
                                    (layer1 "POLY")
                                     (l1  0.5)
                                     (w1  0.6)
                                     (layer2 "ACTIVE")
                                     (l2  1.5)
                                     (w2  1.6)
                                     (type "WIDTH")
                                     (space 0.75)
                                     (overlap 0.5)
     
                       );end of parameters
        
                 let((cv)
                            cv = pcCellView
                             masterpcell(cv type)
          );let 
    ); end of pcDefinePCell    

     

    Is this code wrong? But a generated pcell with this code and when i test by instanstiating this pcell by making new cellviews by going to library manager file>new>cellview it runs fine.But when instantiate the same inside the cellviews using dbCreateParamInst with cellview name "Rule no." i am getting empty set.Why is it so??Hope you got my problem.
