Does Intel offer write-once FPGA or an equivalent product?

Hello,

e-ASIC products is not recommended for new design as this product will be phased out soon.

Apart from that, we only have FPGA product line ups, where users can write and re-write multiple times.

If you want to freeze your design after write it once, there is an option by implementing design encryption.

Hope this option can help you to make decision.
