Quantus (Calibre) Interface

paulinho

I've done DRC and LVS in Calibre and want to use Quantus for extraction. I went to the menu Quantus->Run Calibre-Quantus and the below menu pops up. Is there any user manual which explains how this interface works and how to fill up the below shown form ?

    Yes, it's in the Quantus Extraction User Manual (which you can find by running <QUANTUSinstDir>/bin/cdnshelp and searching for "calibre"). There's also these two relevant sections on Cadence Online Support (the same manual):

    Calibre LVS generates SVRF (binary) database.
    You need to run Calibre Query on SVRF to generate CCI (Calibre Connectivity Interface) or QCI (Quantus Connectivity Interface?) database - which is a bunch of files (agf - annotated GDS file, and several text files), equivalent to SVRF, but interoperable with downstream tools (parasitic extraction - QRC, StarRC, etc.), and located in "query output directory". This directory name / path is programmable (in Calibre Query script), and usually named "query_output", or/and can be located within SVRF directory.
    Calibre Query script is run right after / during LVS.
    CCI / QCI database is the input for parasitic extraction tools.

    Cadence LVS (Pegasus / PVS) generates a very similar database, called PVS, that is absolutely equivalent to CCI (same files, file extensions, content).

    This simple step / flow is absolutely fundamental for understanding of the custom IC design flow, but I have not seen a simple, clear, and concise explanation of this step anywhere (maybe Andrew's links provide such an explanation).
