Updating pcell CDF parameters from an imported file

Wil7104

Hi,

I'm having an issue coding up a pcell to import a file with custom values and then updating the CDF's with these values.  The pcell CDF has a "Load File" option, and this file contains variables/values in this format:

"Offset" "4"
"Offset_MC" "2"
"R_0v" "2222"
"R_L" "0.02"
"R_Q" "1.222e-05"
"S_S" "7.222"
"S_L" "-0.00222"
"S_Q" "2.222e-05"
"S_C" "-7.222e-08"

Here is the section of code that loads the file and attempts to reassign the CDF's:

; ;;; File Loading/Saving code
;
; when( callfrom == "Load_File"
; LoadFilePath = simplifyFilename( strcat(getWorkingDir() "/Hall_model_parameters" ) )
; load( LoadFilePath )
; LoadFile = infile( LoadFilePath ) ;open output log file
;
;
; while( gets( nextLine LoadFile )
; str = parseString( nextLine " \"\n")
; case( car( str )
; ( "Offset" setq( Offset printf("%s\n" buildString( cdr( str ) ) ) ) )
; ( "Offset_MC" setq( Offset_MC printf("%s\n" buildString( cdr( str ) ) ) ) )
; ( "R" setq( R printf("%s\n" buildString( cdr( str ) ) ) ) )
; ( "R_L" setq( R_L printf("%s\n" buildString( cdr( str ) ) ) ) )
; ( "R_Q" setq( R_Q printf("%s\n" buildString( cdr( str ) ) ) ) )
; ( "S_S" setq( S_S printf("%s\n" buildString( cdr( str ) ) ) ) )
; ( "S_L" setq( S_L printf("%s\n" buildString( cdr( str ) ) ) ) )
; ( "S_Q" setq( S_Q printf("%s\n" buildString( cdr( str ) ) ) ) )
; ( "S_C" setq( S_C printf("%s\n" buildString( cdr( str ) ) ) ) )
; );case
;
; );while
; close( LoadFile )
;
; );when

The setq is not updating the CDF's and I am getting a format error after teh first value is read in due to a 't' being reported:

"4"
t
4
"Offset"
2
"Offset_MC"
"R_0v"
0.02
"R_L"
1.222e-05
"R_Q"
7.222
"S_S"
-0.00222
"S_L"
2.222e-05
"S_Q"
-7.222e-08
"S_C"
CDF: An error occurred when evaluating callback.
Callback: Load_File->callback => au1IP_hall_60_sm_b_play_cb("Load_File")

Message: *Error* fprintf/sprintf: format spec. incompatible with data - "Format is '%g', argument #1 is t"

Not sure if my code is just not set up correctly or I'm barking up the wrong tree with the printf statement to remove the "", any help would be appreciated.

Thanks,

Bob

  • Hi Bob,

    The use of printf is incorrect - the printf statement prints out the value and returns 't' but you want the string value. I'm not sure why you are using buildString?  My guess is that each line in the case statement should look more like this:

     sprintf(Offset "%s" cdr( str ))

    ?  I'm assuming here that the parameter value should be a string.  If it should be a number/float format then use cdfParseFloatString() around the string, for example:

    cdfParseFloatString("-7.222e-08")
    => -7.222e-08

    Hope this helps.

    Lawrence.

    Thank you Lawrence, I will implement your suggestions and let you know if it works, the BuildString was used to try and strip out the parentheses (probably wrong fctn for this):

    setq( Offset_MC printf("%L\n" cdr( str ) ) )
    ("4")
    t
    setq( Offset_MC printf("%L\n" buildString( cdr( str ) ) ) )
    "4"
    t

    Thanks again,

    Bob
