What does the cut pattern "farm" mean?

RVERP

I can select it from the list but there's no information to find about it.

It result in something like this (see below) but I find it very hard to predict to outcome of the via pattern

  • The documentation is a bit sparse on this, I agree. You might want to contact customer support about this. I did some research, and:

    • A farm cutPattern is a cutPattern where one or several rows and/or columns of cut are missing every X cuts. For each dimension [X or Y] the same number of missing cut must separate the cut arrays and the same number of cut must be present in the cut arrays.
    • Some examples:
    • If there is no minLargeViaArraySpacing rule in the current constraint group for the current cutLayer the “Farm” mode is not available.

    Here's some examples of how it was set up that I found:

    stdVia with 3xN pattern
    2 missing cuts between array in X (arraySpacingX)
    No arraySpacing Y since there is no pattern in Y direction.

    Another example:

    stdVia with 3x5 pattern
    1 missing cut between arrays in X (arraySpacingX)
    1 missing cut between arrays in Y (arraySpacingY)

    Hope that gives more of a clue about how it can be used?
