As examples, I'm hoping to clock a custom CPU (the ZIpCPU) at 200MHz, to build a custom memory interface that will clock at 200MHz, and ... a flash controller at 200MHz that will generate a 100MHz flash clock. While preparing for this project, I noticed that the web page reference manual for the Arty states that the QuadSPI flash has a maximum clock rate of 50MHz. The data sheet
