As you would expect, chip design is no different. If you are new to chip design, it might take you a few days to read…
Lately I have had the need to do real time video capture from HDMI devices as of late for a project, and while looking around the internet found that all of the capture cards that are aimed at gamers (windows / OSX support only) or full blown production capture (Very expensive, more inputs than I need).

My preliminary research found references to a “magical” SCBO file that could be loaded onto a USB flash drive and booted to remove the password. The normal process workflow is to first…
