I’ve spoken with several customers recently who have, or are in the process of transitioning from PADS Logic to the new DxDesigner. Their reasons were consistent: they needed a component information system, or analog simulation, and/or their designs were getting more complex and need a more robust hierarchy.
Does this describe you? Now may be the time for you to consider the move to DxDesigner.
