I am using DxDesigner for the first time (9.2). When running a Design Rules Check (DRC) there are many rules that can be applied. Many of them make sense to check, e.g. "Property name exceeds maximum length". Others are giving me trouble, e.g. Un-driven Net is an error if I enable it when a net is driven by a transformer with pin type analog. Which ones do you use? Disable? Check, but often ignore the notes or warnings?
Updated 11/23/2010: Under Connectivity here are some I had questions on.
drc-101 Output and bidirectional pins connected together drc-102 Output and tristate pins connected together drc-103 Un-loaded net drc-105 Un-driven Net drc-106 Multiple Output Drivers drc-116 Output directly connected to Power or Ground
Note that I am not doing circuit simulation.
