somethings about panic file

nidon

Dear sir:

 I write a code to generate layout(about more than 80000 layouts),but when I run it,sometimes the CIW window will show the information:

CellView(test1 layout) from lib(test) is saved in the panic file(/path/test/test1/layout/layout.cd-)

To recover do:

dbOpenPanicCellView("test" "test1" "layout")

And then,the icfb will closed by itself,and I have to rerun the code again.

I guess the reason is I generated too more layouts one time,isn't it?

If it is,how shoud I do

Thank you!

    I check my code,and I found I use dbOpenCellViewByType and don't use the dbClose to release the memory generated by dbOpenCellViewByType .

    So,I think it's the key reason.

    And for your suggestions to  improve the speed of script,I did a test for them.
    I use the command groups dbOpenCellViewByType(fileA) ,dbOpenCellViewByType + dbClose(fileB),dbOpenCellViewByType +dbClose+hiSetUndoLimit(0)(fileC) in three files(each file total generate 60000 layouts) .And run them at one time.

    And the result is running time of fileB > fileA  >= fileC.

    I feel very insteresting here,theoretically speaking I use dbClose to release the memory,so the time of file A should be the longest time in the three.But the result is the longest file is fileB(I run these files in three computer).
