I guess they can afford to have defects since a FPGA a big grid of a many of the same components.

- pclmulqdq 3y agoNone of these chips have defects. They usually work with chiplets to improve yield. You used to be able to buy defective devices for a discount when you had a design that didn't use those components, but I don't think those were general-purpose.
- xodjmk 3y agoThis is the old notion of what an FPGA is, and if you notice, these new devices aren't even called FPGA's anymore! They're called 'adaptive SoC's'. Only a small portion of the device is FPGA fabric. But still, even previous gen FPGA's wouldn't be shipped with defects.
- rcxdude 3y agoThis would only work in an application where it's acceptable to run a place-and-route pass for every device to account for the different failures. I don't think it's something anyone has bothered to try to do.
