Hi Casperites, I have created a proper test for the HMCs on the SKARAB. It performs a walking ones test on all 256 bits and the full memory location coverage (2^27-1). There is a script that will test all three mezzanines - very basic, needs work to pass arguments etc. There is a more complete script that will test the HMC mezzanine of your choice. It is located here: https://github.com/ska-sa/mlib_devel/tree/devel/jasper_library/test_models/scripts/skarab_hmc_fc_test (fc = full coverage). You call the skarab_hmc_fc_test.py with the following command: python skarab_hmc_fc_test.py <host or IP address> -m <0,1,2> e.g. if you are targeting mezzanine 0 then you would have "python skarab_hmc_fc_test.py 10.0.0.7 -m 0.
Some statistics: It takes 54.67s to test one HMC on the board and 164s (2 min and 44 secs) to test all three HMCs on the board. It reconfigures the FPGA between link 2 and link 3 then reports the consolidated results. It will indicate if the Link fails or not. We have a faulty HMC in our lab and it is able to detect the fault with this test. Hope it helps if you have any HMC issues.
