Hi Paul, None of these registers is directly configurable from within simulink. They live in the sys_block pcore -- see the relevant base package .../xps_base/XPS_ROACH<x>_base/system.mhs, for where their values are set. The sys_rev and sys_rev_rcs are determined by the hardware. E.g., roach has board id 0xb00b and roach2 0xbabe. I don't know quite how the rest of the version information is encoded in the registers, but in principal if you set the parameters of the sys_block accordingly, you can set the values of those registers to whatever you like.
sys_scratchpad is a blank read/writable register for testing the power pc interface -- it doesn't have any direct interface to your simulink design, so you can't write to it from your model.
