Born out of a bad EOL notice.
The idea came from the wrong side of a PCN. A long-running industrial product — fully qualified, shipping hundreds of units a month — got hit with an end-of-life notice on its primary FPGA. The quote to redesign the board, requalify it for three regulatory regimes, and re-tool the enclosure came back at a number that exceeded a full year of product revenue.
The fix, in the end, was a small daughter board. A footprint-matched adapter hosting a modern PLD device, with level shifting and pin remapping handled onboard. The host PCB was never touched. Certifications carried forward. The product kept shipping. That one adapter saved roughly eighteen months of engineering work and cost less than a week of it.
We built PhatCat Technologies so that fix isn't a one-off favor from a friend with a soldering iron. It's a real engineering practice — with a catalog, a process, and a guarantee that your board keeps running long after the silicon vendors move on.
