    IP business, How to protect FPGA configuration PROM.

    Hi kvingle, You are right. User can't integrate his own into bitstream. This is another business. Exactly not IP business, I would like to sell the IC instead of IP core because IP core price is too high to small company. Anyway, It is a little problem that user can't integrate their own logic...

    IP business, How to protect FPGA configuration PROM.

    I am developing IP core. Generally, IP core price is too expensive to small company. So I would like to sell the FPGA configuration PROM with bitstream of my IP core. But PROM copy protection is a problem. I want to know how to protect IP core and PROM copy. If it is possible, I could sell the...
