SpiceIn reference library list

Yaosan Yeo
Yaosan Yeo over 13 years ago

I have trouble getting SpiceIn utility to properly read in my reference library list, somehow only the first library in my list is properly included. This is how I call the command: spiceIn -param spiceIn.params

Here's how the output (spiceIn.log) header looks like: (notice only analogLib is in the library list; a weird "boaDMFileSys.so" library also appears in the list even though it is not specified in my param file)

=================== Spice In Log File ===================
Parameter file: /tmp/spiceInPa07316
Import Parameters: Netlist file name: /home/yyeo/and1_2x1.hsp       
        Output library name: sandbox_yyeo
        Output View Type: schematic
        Schematic view name: schematic
        Netlist view name: netlist_tmp
        Reference Library List: analogLib boaDMFileSys.so sandbox_yyeo
        Import Sub-circuit List: top
        Top cell: top
        Device-mapping file name: dev.map
        Master Cell for Ground: gnd
        Cells to be Overwritten: <all>
        Schematic Generation parameter file: /tmp/schOpts_spiceInPa07316
        Simulator: spectre
        Output Simulator: spectre
        paramCaseValue: default
        Language: Spectre

The library sandbox_yyeo already exists.
Total number of files: 1.

Netlist File: /home/yyeo/and1_2x1.hsp.

...

 

Here's how my param file (spiceIn.params) looks like:

spiceInParams = list(nil
        'conn2schArgs   "-MIN_CROSSOVERS -FAST_LABELS"
        'language       "HSpice"
        'netlistFile    "/home/yyeo/and1_2x1.hsp"
        'outputLib      "sandbox_yyeo"
        'refLibList     "analogLib basic primitives esdLib"
        'devMapFile     "dev.map"
        'overwriteCells "all"
)

 

My Cadence version is IC 6.1.4.485. Thank you!

    Hi Yaosan

    It would be good if you can retry using a newer version of IC614 or perhaps latest version of IC615. The problem might resolve by itself. Your input files looks fine so perhaps this might be an old bug. It would also be good if you can upload the spiceIn.log file as an attachment for more checking. : )

    Thanks
    Quek

    I just want to report back that this issue was resolved in IC615. I believe the latest version of IC614 will probably work just fine as well. The issue I encountered is most likely a bug specific to the IC614 version that I was using. Thanks for the feedback and suggestion Quek.

    I have some new issues with the SpiceIn utility. When I spice in a circuit, all the subckt will be created in the output library even if they can be found in one of my reference libraries listed. It seems to me that only primitives works with the reference library list.

    For example, this is what I have (cell_a is a subckt of cell_b):

    lib_a/cell_a/layout
    lib_a/cell_a/schematic
    lib_a/cell_a/symbol 

    lib_b/cell_b/schematic

    If I try to spice in cell_b and specify lib_b as the output library, even if cell_a can be found in lib_a, which I have listed in the reference library list, the utility will not use it and will simply create a new cell_a in my lib_b.

    Is there any easy way to NOT create a redundant cell_a in my lib_b and have the cell_b's schematic references lib_a/cell_a/symbol instead of lib_b/cell_b/symbol? Thanks!

    Sorry for double posting. I think I figured out the issue. The issue is related to overwrite flag being set to "all". In this mode, the subckt will be created in the output library only. Any symbol found in reference library list will be ignored (except primitives).
