How to ignore FILL cells from Encounter in LVS Assura?

Kabal

I have imported some design in Virtuoso Layout from Encounter, which has some FILL cells: FILL1, FILL2, NWSX. When I do LVS with Assura, I want those cells to be ignored. This is very small part of the bigger problem desribed in some another thread, but beacuse this issue is kind of specific just to Assura I would like to ask about it separately in this thread so that someone who knows issues with Assura can give me idea.

I am attaching the error log of LVS, and the snapshot of settings how I make Assura ignore those cells using ignoreCell command. The problem is that at the beginning of the log it actually says that its going to ignore those cells, which is fine, but then it again throws error at the end saying that FILL1,FILL2,NWSX are not defined. Why is it doing it? Am I doing something wrong?

  • I wouldn't have expected that you need to ignore these at all. In fact you shouldn't really ignore them because then it will not use any routing inside those cells.

    These cells aren't in the Verilog, I assume? If so, I am assuming you're not specifying ?dspfCells and if you are, the fill cells aren't in the list of DSPF cells?
