PPM: Energy, BCID and Timing Calibration
May not be required/doable for the slice test? Requires Calo calibration systems - though analogue input of some kind will be available?
Can be done one PP/ROD crate at a time (but note orthogonal division
of PP and Calo partitions).
PPM-CPM/JEM Timing and Connections
Needs coherent events read from PP RODs and CP/JEP RODs.
CP and JEP Backplane Checks
Can be done one ROD crate at a time.
CMM-CTP Transmission Checks
Needs events from at least two ROD crates.
Trigger Functionality
Needs coherent events from all available ROD crates.
Performance? For test data, rate will be limited by the speed of
loading new test vectors.
Load 128 slices in all PPM channels. Run 8 L1As then stop triggers.
CTP deadtime then gives 88us to load next 128 slices in 64 channels
in 16 PPMs per crate (about 128kb/crate).
Q: for final system, if we could run at max L1 rate, can we use
custom level 2 algorithm to check expected outputs?
