very same fpga chip alone is more expensive than DE-10 nano https://octopart.com/5cseba6u23i7n-intel+%2F+altera-88365716 Be sure to send your thanks to EC, FTC and the Antitrust Division of the DOJ. Altera and Xilinx mergers clearly were super beneficial to customers and the market, competition has never been better with both competing by rising prices and cutting volume in unison.
But I wouldn't place too much blame on the companies - COVID wrecked a lot of supply chains as well - as anyone who runs emulators on RPis will be able to confirm.
Covid showed companies new way forward. Cut supply and bump prices, this is the source of all semi shortages. There was no earthquake, no one ran out of rare ingredients, corporations simply cut fab orders.
rpi shortage is a direct result of Broadcom (Avago) deciding to stop manufacturing chips that dont generate hundreds of millions in revenue a year. FPGAs were same deal, post merger Xilinx/Altera cut manufacturing.
