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

    I am thinking that perhaps it might be better if you use make use of snapshot function from a typical file server (e.g. NetApp). It would be more efficient and the snapshot timings can be easily configured. I have not tried writing a skillscript to take snapshots but wouldn't that slow down Virtuoso since you plan to run it at 10mins interval? Even though you plan to run it in the background, I think executing a cmd at regular intervals would still have an effect on Virtuoso. Perhaps Andrew or Lawrence has better ideas on how to do it. : )
