So I'm interested in taking in a signal from one of the dedicated SMA clock inputs on the roach, running it through the DCM, and then out of the GPIO SMA. I specifically want the DCM because I can then actually lock multiple outputs together. Within the casper toolflow, there doesn't seem to be any access to these clock inputs besides as clock sources for the roach.
>From what I understand, I either need to figure out how to make a yellow block to access these inputs or splice in some verilog of my own. The verilog part seems somewhat inevitable, as it's really unclear how I give the DCM directives otherwise. Any ideas on how to go about doing this?
