Problem with QRC execution

w888ku

Hello all! I have made a simple CMOS inverter circuit schematic, made its layout and have successfully passed the DRC and LVS. However, when I try to run the QRC on my inverter layout, it gives a failure. When I checked the log file, it gives me a warning that the technology has not been specified. However, I have specified the av7rfQRC in the QRC setup. I have searched on the web for a solution to this, but so far have not gotten a working solution for my case. Please let me know if anyone on the forums can offer advice on how to resolve this issue. Any help is greatly appreciated.

P.S: I am giving a copy of the log file contents from my qrc log file below if more detail is needed:

  • I think that message is coming from the libInit.il of your technology library - I don't think it's a QRC warning. It's probably from the IBM PDK (and I can't help you with that as I don't have access to it).

    However, the real problem is probably the

    *WARNING* (DB-270210): dbOpenCellViewByType: library 'esd7rf' does not exist

    messages. On the QRC form, underneath where you've selected extracted view output, there's a checkbox called "Enable CellView check". Make sure this is unchecked (i.e. off). This will prevent QRC complaining if it can't find the cellView in the library (unless that component actually exists in the layout being extracted). Normally it checks for missing cellViews even if they are not used.

    Regards,

    Andrew.
