Problem with auto via using custom via variant

blankman

Hi,

 

I’m, looking to create a custom via variant, and then use this in the auto via tool. However when I go to do this the number of rows/columns generated doesn’t fill the selected metal area, only uses the number defined in the custom via variant. Is there a means of setting the auto via tool to fill the full metal area using the custom via variant?

 

Thanks,

Brian.

  • Brian,

    O.K. I can see what you are trying to do.

    The auto via will not change the parameters of your via variant. Once created, the variants are fixed.

    In fact you will need 3 (M1-M2, M2-M3, M3-M4). But you will still only get the number of cuts defined in your via variant.

    So what you need to do is not use any via variants at all.

    In the options form you will see a list of all the layers and vias. Select the standard vias (if you haven't already done this) and set the cut spacings to the values you want. (don't forget to click the checkbox to force the override values.

    The tool should then be able to change the number of cuts to fill the overlap area.

    If you are trying to fill polygon areas you may get different results depending on the software version you are using. Earlier versions could only create a rectangular  via region. Later versions can generate diamond-shaped regions for 45 degree shapes
