Make a copy of the Kit

samer1

Hello,

I am working on a project where I need to add some custom layers for layout. In order not to mess with the original Kit, I want to make a copy of it and do all the modifications  to that copy such that any changes in it does not affect the original kit. 

Any thoughts?

Thanks

    Why not just use an incremental technology database rather than a copy of the kit? That's exactly the kind of thing it's used for.

    So, create yourself a library and rather than "attaching" it to your technology library, use the "reference" choice instead. Having done that, you can use Tools->Technology File Manager in the CIW to Dump the technology file for your library; you'll see that it contains just a controls section with a reference library specified. You can then add your own layer definitions (for the additional layers) into this ASCII technology file - for example syntax see <ICinstDir>/tools/dfII/samples/techfile - there are several files in there. Define just the techLayers section within layerDefinitions for the layers you want, plus the techDisplays section to define the Layer Purpose pairs you want, and how they would be rendered.

    Of course, you can add constraints etc for these additional LPPs if you need them.

    Doing this means that your original kit is unaffected, but you've "topped up" the technology with your additional information. Anyone else could then attach to your new library and pick up the compound (incremental) technology database.

    Regards,

    Andrew.
