Figure A–4. Resynchronization Registers—Stratix II Devices with Fed-back Capture
Notes to
(1) IP Toolbench automatically inserts the intermediate resynchronization registers, depending on your choice of resynchronization phase.
(2) IP Toolbench automatically inserts these registers if the design needs them.
