Differential signals postfixes (defaults: _P and _N).
Recognize differential signals: Turns on extracting differential structures info from HDL files. The option by signal postfixes tells PADS I/O Designer to use the specified postfixes during differential pairs search.
HDL source: Enables the extraction of differential signals.
Default bus direction: Specifies a default bus direction for scalar signal groups.
Separate bus pins: Does not create bus pins during update from the constraints file.
Recognize differential signals by postfixes: Enables the extraction of differential signals during constraints file update, based on defined postfixes.
Autodetect clocks: Turns on recognizing clock signals based on a regular expression. Autodetection applies to reading signals from files (HDL source files, constraint files).
Overwrite schematics instead of update (DesignView/DesignCapture flow only). If this option is enabled (the recommended setting), the entire PADS I/O Designer generated schematic is overwritten with the new version during export.
Automatic SSO Check: Automates running of the Xilinx SSO (Simultaneous Switching Output) Check.
