We ship the XC5VLX30-1FFG676C to user, but user said the marking is not the same as they bought before.(User didn't tell us where they bought from before.)
User said top marking should be in the middle of the IC, but our part's marking is on the left side of ICs.
Could you tell us the marking as attechment is correct or not ?

Can you please attach top marking of device? It seems its missing from your post.

The part marking on the device in your image looks correct and the up to date V5 marking. The customer probably has the older V5 parts with ink marking. Checkout the notice XCN13015 linked by other above showing the transition to laser marking. The only thing that seems off to me is at the bottom. If your customer still needs assurance you can try providing a PO copy to them to verify it was obtained via Xilinx authorized channel.

I checked internally, this part is not authentic (shown in image).
Please check this part purchased from Xilinx autorized channel or not.

That second image is of a valid lot. However as many of us have stated already on this thread you can verify the parts as authentic by sourcing the devices from Xilinx authorized distributors... This can be verified via a purchase order or PO. If your customer needs assurance of authentication send them a copy of the PO that was received when the lot was purchased/received from a Xilinx authorized distributor.
