DRC clean with encounter, DRC error with calibre

archive

    Hi,
I get a DRC clean and no DRC violation in my encounter log file after doing globaldetail routing and adding filler.
But as I am merging my design gds with stdcell gds and using calibre for DRC checking I get so many errors!
Could you please help me on the procedure i have to take to have a clean DRC using calibre?
can I load the DRC report of calibre and ask encounter to solve those DRC error?
As i am looking at most DRC error in my design are concern to filler. so basically I have so many empty area between nwells and has not been filled with fillers.

Thanks,

Houman

  • Hello Houman,

    Glad to answer your question .

    Its very clear that Encounter cant fix such calibre reported violations for Nwell or Pwell spacing . As LEF file does not have such rule .

    You have to fix all of them manually and its very easy .

    Fixing procedure : and fill cell adding
    1. you should see that there are no empty site in the core area before adding filler (SUBCON ) cells .
    2. If you have any placement blockage please delete it manually ,as Encounter cannot delete placement blockages .
    3. Make sure that apart from Macro Block halo , there is no empty area.

    To load violation marker on to Soce .
    loadViolationReport -type Calibre -filename < File name drc.err >

    Hope this will help you ,

    Regards,
    Mohan
