Measure the distance between poly

RicardoGV1

Hello everyone,

I'm trying to measure the distance between resistors, to then check if there is anything strange like a resistor having its fingers space 0.25um  but then the space to a dummy resistor farther than the 0.25.

I found this attached post which create rulers between the layers, the thing is that only works on the current hierarchy, is there any way to do it on all the lvl's?, to kind of flatten everything, create the rulers and then erase everything. 

If anyone could help me to see a better way of doing it or guide me a little bit for doing the flattening stuff would be great. 


create rulers/measurements for width of (and spacing between) shapes in a given area

getVersion()->virtuoso version 6.1.8-64b

getVersion("virtuoso")->sub-version IC6.1.8-64b.500.22

Thanks in advance

Best regards,

  • Hi,

    I guess you could adapt the script to increase the level depth to parse:
    For instance in dbShapeQuery use the startLevel and stopLevel arguments

    Or you could write your own script.

    It might be overkill but I guess I would try by getting all the shapes in provided bbox using dbShapeQuery
    And then for each shape I would use dbGetNeighbor in each direction

    Hope this helps

    Cheers

  • If you want a to just measure you might want to try the Dynamic Measurement option with the Ruler function

    If you want a print out or write to a file the functions AurelBuche mention are good.
    ( if you are measuring polygon dbGetNeighbor has the limitation of measuring to the bounding box of the shape )
