Vivado - 2013.x Vivado Synthesis - What is the purpose of "out_of_context" option used as part of the -mode switch?

Description

What is the purpose of "out_of_context" option used as part of the -mode switch? How should a user use this option?

Solution

Starting with 2013.1 Vivado Synthesis, the -no_iobuf switch is hidden. It is recommended to use the "out_of_context" option as part of the -mode switch instead of the -no_iobuf switch. The out_of_context mode turns off I/O buffer insertion for the module and marks it as OOC, to facilitate its use in the HD flow.

The -mode out_of_context switch option can be either passed to the synth_design TCL command or added to the More Options in the Synthesis Settings within the Vivado IDE.
