    Closed: Re: DRC and LVS in Calibre

    As ljp noted, if it is the specific error, check the PDK documentation. Calibre provides the tools, but the PDK creator defines what is actually being checked.

    If it is how to use the Calibre...

    Closed: Re: Problem when installing Calibre

    What version of Calibre?

    One possible reason for the incompatibility is if you have the 32-bit installer; Java 1.6 was the last one that included certain 32-bit packages. (Per an article on...
  3. Closed: Re: Post- simulation use calibre pex view, all parasitic capacitance connected to a n

    Hi Andy-

    I haven't used xRC in several years, but back when I did, net 0 was reserved for substrate. Are you doing multiple power domains? Particularly with the old versions that could be tricky...

    Closed: Re: Import a layout from Encounter to Virtuoso

    If the only reason to go to Virtuoso is to run Calibre, try running Calibre from the command line. Find out where Virtuoso is looking for the Calibre files and check for __runset__ (two underscores...

    Closed: Re: What do calibre PERC tools do ?

    Assuming you have access to the manuals, there are many ESD examples in calbr_perc_user.pdf; also, chapter 10 of calbr_solns_pv_user.pdf. Some of the examples also have files in the...
  6. [SOLVED]Closed: Re: Calibre Parasitic Extraction of TSMC018 Gate-Driver

    Hi JE-

    The Calibre documentation is typically in the installation directory. (There were some releases around 2010 or 2012 that did not include it because the download had become so large.) ...
  7. [SOLVED]Closed: Re: Calibre Parasitic Extraction of TSMC018 Gate-Driver

    CalibreView is specific to Cadence tools; if you are not running a Cadence flow with Calibre just for DRC/PEX, you are better off with one of the other spice-based formats. Also, every so often...
  8. Closed: Re: How can you use Mentor Calibre to flatten a hierarchical DRC database?

    Setting drcCellName to 0 is probably going to cause only one instance of a hierarchical cell to be reported (but yes, using top-cell coordinates). Probably not what you want.

    For the batch command...
  9. Closed: Re: In a GDS with multiple cells in parallel (no one topcell), how can I create a top

    In the Calibre DESIGNrev reference manual (calbr_drv_ref.pdf in Calibre's docs directory), see the example in $L create cell -- it sounds similar to what you want.
  10. Closed: Re: How can you run Calibre -drc both FLAT and HIERARCHIAL?

    Sorry, Majd, you can't do that in one run, though you could modify the rule file to use variables and write a shell script to kick off both with one invocation. (You need the variables so that the...
  11. Closed: Re: How to accurately measure width of Circular Object using SVRF command in calibre

    Are you sure it is not inaccurate because most layout programs are only approximating circles?

    Anyhow, you can measure the diameter with DFM PROPERTY. There are some examples on the support...
  12. Closed: Re: LVS Error with Mentor Calibre in hierarchy mode only, but LVS clean in Flat mode

    It might be how the text is attached to nets. Verify these settings:

    * Top level nets are texted properly, with Virtuoso streaming the text objects correctly to GDS.
    * The top level text layer...
  13. Closed: Re: Floating input/output Problem in post simulation

    You might be able to get rid of them with PEX NETLIST VIRTUAL CONNECT YES (it joins nets with the same name) but this is really only recommended for subsystems -- parasitic extraction is layout...

    Closed: Re: dbdiff (gds comparison with cadence)

    Keeping in mind that the FastXOR output is generally easier to use to identify differences, you could use the "-include_layer <file>" argument. The file should have each layer you want to include on...

    Closed: Re: Mentor Calibre nmDRC vs DRC

    Hi Allen-

    You don't mention specific versions, but chances are good that the license manager software (FlexLM) got updated. Calibre versions that announced a license server upgrade were 8.8_1...

    Closed: Re: Mentor Calibre nmDRC vs DRC

    Hi Allen-

    nmDRC/nmLVS can run all the old Calibre DRC/Calibre LVS files. The nm products can handle larger design sizes and TVF commands, which the older products didn't. There are also some...
  17. Closed: Re: Calibre loaded by Virtuoso 6.1.7 automatically

    It should be somewhere in the .cdsinit file. If you are looking at the specific syntax used, the Calibre Interactive manual has some additional information.

    [SOLVED]Closed: Re: ERROR_during running LVS

    You have actually got two errors there -- one about not finding the matching subcircuit in the file, as ErikL noted, and one about cannot read source. I suspect the second error can help you figure...

    Closed: Re: post layout extraction

    Hi Vaah-

    You'll need to talk to the person who put together your tool flow. If the SDF file appears when you run Calibre, your scripts are presumably calling the Time-It add-on (a separate...
  20. Closed: Re: Calibre LVS errors for a design generated in Encounter

    Correspondence points are influenced by the hcell list -- you don't want to list everything, or your run can get slow. nmLVS also matches on cells that have the same name. (Cell names may be...
  21. Closed: Re: Calibre LVS errors for a design generated in Encounter

    That could be it. When you say there were zero geometry and connectivity violations in Encounter, are you sure you ran the checks at the top level?

    For the Calibre issues, it is odd to have over...

    Hi Vaah-

    The .pex file contains your lumped parasitic capacitance. You should also have regular netlists in the format you specified. (Check your SVRF rules for a PEX NETLIST statement, or if you...
  24. Closed: Re: Exist any free version of Calibre DRC to use in FreePDK45nm??

    I see in your profile you are associated with a university -- many of them have the tools through a higher-education program MGC offers. Might check with your electrical engineering department.

  25. Closed: Re: Calibre Interative could not be licensed sufficiently

    The best place to ask about correct setup for licensing is your system admin or CAD group, assuming there is one, because every place has a different mix of software and environment.
