skill ruby interface for openaccess

skillseeker

Hi,

I am asking for the best method to approach this problem.

 

I would like to execute skill commands on a Cadence database in a unix shell command line. Ideally i would not want to worry if the ICFB session is active or not. So i would prefer not to use ipc protocols as my understanding is these require you to connect to a live Cadence ICFB session.

Also would not prefer to run icfb -nograph mode and execute skill this way.

My OS platform is SUSE11. The programming language that needs to interact with the skill output is ruby.

What is the best method to achive this case.

 

Thanks
 

 

 

  • It's not that clear what you're actually trying to do. If you want a cut-down executable which can interact with the database, you could use dbAccess. 

    You'll have to run some sort of executable with SKILL access to be able to run SKILL functions.

    I don't understand what you're trying to achieve and what role Ruby has in this.

    Maybe a clearer question with some specifics might help?

  •  Andrew,

    Trying to build a eda tool that uses information from Cadence Database. Ideally i would like to not use interprocess communication as this requires a running instance of ICFB. I am looking to access Cadence database information witout having to run "icfb". I looked at the dbAccess which is useful but would not be a complete solution.

     Is there a way to access the Cadence database for example here is what i intend to do.

    1) access available libraries defined in the cds.lib path and get all the cells available in each of those libraries. 

    2) get all the views available  and traverse the hierarchy to build an xml representation of the file based on a switch view and stop view.

    Can these two steps be done without having to have a running instance of "icfb". If there is any methodology that exists today on SUSE platform that would be helpful to know.

    Thanks

  •  Si2 (the owner of OpenAccess) provides a Ruby scripting interface for its members. Cadence supplies a cds.lib plug-in that you can use to read the cds.lib file. Most of the Virtuoso database is in the OA standard, some new functionality is defined in oaAppDefs which are private to Virtuoso.

    You should be able to access the database for what you are trying to do using the script. If you have to read pcells, you can read them using the Express Pcell plug-in included with Virtuoso with your script.

    See the Virtuoso documentation on these plug-ins.

  • Since the original poster posted this in the Custom IC SKILL forum, and was asking about SKILL, this can all be done in SKILL using dbAccess, as I originally suggested. Not really sure what the objection to using SKILL is in this case.

    Ted is of course right, other language bindings for OA can also be used.

    Andrew.
