The GOL input links were interconnected by loopback fibers from MRODIN
to MRODIN, so that sender and receiver were in different clock domains.
Test software that generates CSM-like input data on the GOL outputs was
running on the MRODIN DSPs and software that spyed on the event data and
performed a full check on the data in real-time, was running on the MRODOUT
DSP. The full hardware chain from MROD-X GOL; input up to, but not
including, the SLINK output was thus continuously active (in this case: 6
GOL inputs and onboard RocketIO links) generating and processing event data.
FPGA silicon temperatures were read out by the test software:
