The reason I ask is I would like to interface a 40 pin daughter card with an HSMC port using an HSMC to 40 pin debug header but the clocks don't line up. If it is possible, how would I go about assigning this in Quartus? Thanks. --- Quote End --- Hi, there is no basic problem to use an FPGA I/O as a ock driver. You have to assign your clock signal to an I/O, which is connected to the HSMC port. You can do that with the Assignment Editor or with the Pin Planer tool in Quartus.
