SSO Check

PADS I/O Designer enables you to run the Xilinx SSO (Simultaneous Switching Output) Check.

PADS I/O Designer supports many, but not all, older families. A grayed-out SSO option in PADS I/O Designer indicates that the option is not available for the current vendor or part family.

Note
	For in-depth information on Xilinx SSO, refer to the Xilinx documentation available on the Xilinx web page.

The settings for the SSO Check can be found in Database Properties, on the Advanced tab. These are:

SSO Package Allowance

SSO Bank Threshold

To run the SSO Check, go to Tools > Simultaneous Switching Output Check.

Automatic SSO Check

You can set up the SSO Check to run automatically when an assignment has changed, by selecting Setup > Settings, clicking Advanced, and checking the box for Automatic SSO Check.
