Stackup

The conductor stackup can be taken from either the matrix file or from a specialized stackup section. The stackup section can include actual material references but it is often difficult to interpret so we rely on the matrix file.

STEP {
    COL=1
    NAME=PCB
}


LAYER {
    ROW=1
    CONTEXT=BOARD
    TYPE=COMPONENT
    NAME=COMP_+_TOP
    POLARITY=POSITIVE
    START_NAME=
    END_NAME=
    OLD_NAME=
}

LAYER {
    ROW=2
    CONTEXT=BOARD
    TYPE=SIGNAL
    NAME=TOP
    POLARITY=POSITIVE
    START_NAME=
    END_NAME=
    OLD_NAME=
}
