We have no EPICS driver for this, yet. The plan is to, first develop userpace library that would abstract away details and let the user work with clocks, triggers, data channels..; compared to to "raw FPGA registers". Then, the EPICS driver will be built on top of this userspace library.

FYI ... Have a look at

http://www.i2a2.upm.es/idi/instrumentacion-aplicada/sistemas-de-adquisicion-de-datos-avanzados-2/irio-technology/

for such a generic approach with an intermediate user space library - in that case targeted at NI's RIO architectures (FlexRIO and compactRIO).
