Assura extraction to ignore certain cells

kawan

 Hello,

I am trying to run an extraction of  a top level cell(say "test_top"). Hoever there is another cell inside ("Cell1") that I do not wish to extract.My expectation is I get get a extracted view called "av_extracted_C" which I can refer to in the hierarchy editor of the top level testbench ("test_top_testbench"). So  "test_top_testbench" has among other things,  the cell  "test_top". In the hierarchy editor I was expecting to use the view "av_extracted_C" for "test_top". I then expect the hierarchy editor to also show "Cell1" and have me select the desired view. Problem is this is not happening.

Assura > Run LVS .. Here I selected "Modify avParameters" to set it up as ?ignoreCell (  cell("Cell1 layout CAL")  ) but that did not work. 

Then I tried  ?preserveCells (  cell("Cell1") excludeCell("Cell1") ) ... but that did not work as well.

 

Any ideas? 

Thanks

    I dod not see any warnings related to any other cell name in the hierarchy except for this one cell called "RCCAL_INT"

    Almost feels like a typo in the hrcx list but it it not.
