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,

  • Hi Messi,

    The problem is that you've parsed each line in your rule file to be a list of strings, and so you're passing a string where a float is expected.

    Use the function cdfParseFloatString or atof to convert it to a float when calling dbCreateParamInst. cdfParseFloatString has the benefit of handling suffixes like "k" and "u". So:

         dbCreateParamInst(
           cv mastercv i list(0 0) "R0" 2
         list( list(  "w1"     "float"                     cdfParseFloatString(nth(2 ruleTable[i])))))

    Note your code still has the unnecessary ruleTable~>? in the foreach loop.

    Another thing you might want to consider to make the code more readable is that rather than using rexMatchp, you could do:

           case(upperCase(nth(1 ruleTable[i]))
             ("WIDTH"       
                dbCreateParamInst(
           cv mastercv i list(0 0) "R0" 1
                   list(
                      list( "w1"      "float"  cdfParseFloatString(nth(2 ruleTable[i])))
                      list( "layer1"  "string" nth(0 ruleTable[i]))
                      list( "type"    "string" nth(1 ruleTable[i]))
                  ))
       )

      ("SPACE"  
       dbCreateParamInst(
           cv mastercv i list(0 0) "R0" 2
    ...

    In fact better still would be to do:

    ruleData=ruleTable[i]

    At the beginning (within) the foreach loop, so you don't have to keep looking up the entry in the hash.
