interactive creation of rod path

drdanmc

I know how to create a path with rodCreatePath() which gives some flexibility in terms of programming the type of path.  For example a bus of varying bit width, metal width, spacing, layer, etc.  However it stinks for interactive use.  I can easily draw a MPP interactively but my selection is from a limited set of paths I've pre-defined.  Is there a simple way to combine them?   Basically is there something like rodCreatePath where I can use a path I've defined via skill (possibly from inputs in a custom dialog) but draw the path interactively?

Thanks

  • Hi Dan

    I think perhaps your question is as follows:

    "How can I use rodCreatePath together with the MPP templates defined in Virtuoso techfile?"

    I think COS article 11323850 would be helpful for you:

    Can I create a Multi Part Path in SKILL based on a technology file template?


    Best regards

  • Hi Quek,

    Thanks for the pointer to that solution. That actually helps with something else I've wanted in the past but it is actually not quite what I was looking for here.

    That solution lets me use skill to draw a MPP which has been defined in the tech file. What I'm looking for is a way to interactively draw a rod path which has been created on the fly as opposed to defining a MPP template. There is leHiCreatePath() for interactively creating a path. I'd like a leHiCreateRodPath() where I pass in the layer, width, offsetSubPath, etc.

    There seems to be an undocumented leHiCreateMPP so maybe I could make a template on the fly, call leHiCreateMPP, and then delete the template but that seems like a real hack and I'm not sure I even can delete a template.

  • Hi Dan,

    The leHiCreateMPP function is actually public, but not documented for some long-forgotten reason. So I filed a CCR on your behalf to get it documented.

    Anyway, you could either use this in a slightly convoluted way, or use enterPath() to create your own user interface to digitise the master path, and then use rodCreatePath() to create the MPP from the points entered. You could have an options form on the enterPath to allow you to enter the width and so on via an F3-options form.

    I'm sure there are solutions for this (and maybe on this forum - I suspect if  you search (using the magnifying glass in the top right corner of this page) for rodCreatePath enterPath you should find a few bits of code...

    Regards,

    Andrew.
