Paper schematics into Virtuoso

AsicMax

I am trying to figure out a way to get scans of paper schematics into "schematics" e.g. Virtuoso. The original schematics are in poor enough shape that I doubt an automatic flow would be helpful. I was thinking of some way of getting the image onto a schematic page as "symbol" like a page border, then manually instantiating components and wiring them up "tracing" the scanned image. But symbols are built from lines and arcs etc, not raster images that are imported.

 Any ideas on how to do this?

  • My immediate reaction to this was "pay an intern to do it", but if you really wanted to, you could (I guess) use something like the SKILL code in solution 11723246 to create a symbol based on a bitmap image. You'd want to do some serious colour/greyscale reduction in an image processing tool first (to make it easier to import), and then use the code in that solution.

    You could then use geBackgroundCellView() from the schematic editor to display the imported symbol bitmap.

    I think generating the bitmap symbol could be very slow, and even when you've done this, the chance of aligning it sensibly with any kind of drawing grid so that you can trace the schematic and end up with "on grid" schematics which match your symbols, is extremely remote.

    So treat the above as a thought experiment; I wouldn't waste time trying to do it!

    Regards,

    Andrew.
