Encounter does not stream out all cells into a GDS

archive

Hello all, I used First Encounter v4.1 for place and route, and using following command, a GDS format of the design was made: streamOut ~/WiMax576_0.7.gds -mapFile ~/gds2_cmos90.map -libName WiMax576 -structureName decoder576 -stripes 1 -units 1000 -mode ALL now, in Cadence Virtuoso, all standard cells are appearing like red boxes, and Calibre-DRC stops reading the GDS by following error: ERROR: Cell FILLERCELL32 is referenced but not defined. *** Calibre finished with Exit Code: 4 *** Can someone help me please to resolve the error? Thanks, Ali

  • Hi Kari,

    I am running Encounter using LEF and lib files of cmos90nm technology. The library of cmos90nm is defined and available in the library manager of Virtuoso (layout/symbole/abstract/...). When i finished the place&route, i exported the design into a GDS file. When the GDS file was imported in to the Cadence, PIPO.log showed some warrning as follow:

    CellView Rectangles Polygons Paths Ellipses Labels Instances Arrays Dots
    ******************************************************************
    decoder576/layout 1642 0 2389153 0 2 3171777 0 0
    (BFLVTX2/layout) -- (referenced, but not defined, no data created).
    (CTBUFLVTX6_0/layout) -- (referenced, but not defined, no data created).
    (CTBUFLVTX12_0/layout) -- (referenced, but not defined, no data created).
    .
    .

    so, Bob told that the GDS of standard-cell library should be merged into my design when streaming out the design from Encounter. But i am not given such GDS files. mayby CMC ot STM doesn't support it.

    Is there any method to generat the required GDS files?
    Or do I have any mistake in using tools?

    Thanks,
    Ali
