rda_Input(ui_captbl_file) array variable

tiEngr

Hi All,

Im writing a script to save encounter DB for export. The directory will contain all the lefs, libs, sdc, and cap table files. 

In order to do this I  have to update "rda_Input" array elements and save using saveDesign or saveConfig. Which was no problem updated except for rda_Input(ui_captbl_file)  element.  Seems like what ever is in the gui form that will be saved using saveDesign or saveConfig. Even if I update this variable.  For example:

 

encounter 6> set rda_Input(ui_captbl_file) "someFileName"
someFileName
encounter 7>  puts $rda_Input(ui_captbl_file)
someFileName
encounter 8> saveConfig some.conf
encounter 9> grep ui_captbl_file some.conf
set rda_Input(ui_captbl_file) ""

 

 encounter 14> set rda_Input(ui_leffile) "./lef/msl200_50hpa07_tech_4layer.lef"
./lef/msl200_50hpa07_tech_4layer.lef
encounter 15> saveConfig some.conf
encounter 16> grep ui_leffile some.conf
set rda_Input(ui_leffile) "./lef/msl200_50hpa07_tech_4layer.lef"

 In this case, Im using empty encounter shell. No design/lib loaded. 

 

Thanks

  • HI Irfan,

    You might want to consult the public "saveTestcase" command that manages creating a self-contained testcase.  More here:

    Would you have a look and let us know whether this meets your needs?  I'll have a look at whether I can reproduce what you're saying with ui_captbl_file.

    Thanks,

  • Thanks Bob,

    Thats exactly what I needed. saveTestcase does a complete archiving of  DB.  Very useful command.  Have a look at the captbl variable. Its just strange that even after update it keeps value from gui form. I guess once we update, gui form should get updated too.

    Thanks again for a quick reply,

  • I did some testing in this area and see what you're saying.

    I agree it's strange that the captbl variable behaves differently than the lef variable.  I noticed that if you "commitConfig" before "saveConfig" that the values are retained. It appears there's some synchronization between the TCL variables and what's displayed in the GUI that's inconsistent depending on the variable.  That being the case I filed a CCR to see if we could improve the variable and make them behave consistently.

    Thanks for pointing this out- appreciate it.

     

  • Thanks Bob, for checking into it.  Just wanted to point out odd behavior of TCL variable inside the shell. I do have one core dump scenerio.  I will post in a different thread.
