Virtex-5 Configuration - What should be done with the Din pin in SMAP mode?

Description

The DIN pin is a dedicated configuration pin in Virtex-5. What should be done with this pin if SMAP mode is being used?

Solution

The pin can be left floating or connected to ground as the connection in the device will not affect operation after the INIT pin goes High and the mode is set to SMAP.

For improved SSO noise and power design considerations, the pin can be tied to ground.
