Saving snapshots of layout, schematic views

jalwyn

Hi,

I am trying to save the current layout/schematic which is being edited to a snaphot cadence library.This snapshot is taken at specific time intervals say every 10 minutes. I would retain 2 snapshots the latest one and the previous 10 minutes. I do not want to save the view being edited. I did write a skill code for this task, the skill code runs in the background and as able to create the snapshots. The problem was I could not undo(hiUndo()) some edits in the current cell view, as the the undo operation probably tried to undo the operations done by the background skill code. I am not sure if my understaning is correct. Can anyone please advice if there is a better way to handle this.

I am providing the skeleton of the skill code I wrote

 procedure(saveSnpSht()
 prog(()
  ;This procedure saves the existing snapshot to old snapshot and saves the
  ;current cell view as new snapshot
 )
)   

procedure(CCS_snpShot()
  hiRegTimer("saveSnpSht()  CCS_snpShot()" 6000)
)

I will execute  CCS_snpShot() in ciw, this keeps running in he background while I continue editing the cell view.

 Thanks and regards

John

  •  Hi John,

    I hope you are using IC61x as there are new capabilities ther, such as hiWindowSaveImage():

     

    hiWindowSaveImage(
  [?target g_target]
  [?path t_path]
  [?format t_format]
  [?toplevel g_toplevel]
  [?quality n_quality]
  [?delay n_delay]
  [?timeoutBeep g_timeoutBeep]
)
  => t | nil

    This lets you save an image to various formats such as PNG, BMP, JPEG etc.

    And in IC614 there is another related function that you might be interested in, hiGenerateThumbnails():

     

    hiGenerateThumbnails(
  ?lib g_lib
  [?cell g_cell]
  [?view g_view]
  [?sizes g_sizes]
  [?output g_output]
  [?verbose g_verbose]
)
  => thumbnails | nil

    This creates a 128x128 size PNG of the cellview in the cellview directory.

    If you are using IC514 then I think the options within the tools are limited, you might print/plot a cellview to a postscript file. The Tools->Camera utility calls "xcam" behind the scenes, so this may not be much different than what you were thinking originally?

    I hope that the above information helps,

    Regards,

    Lawrence.
