-- The modular VME Test system:
a platform for ATLAS developments -- (links hereunder point to a picture of the item;

The VME motherboard serves as a carrier
for two CMC (Common Mezzanine Cards). Its front-panel
is tailored to allow "massive" Input/Output for certain applications, required
in the ATLAS Level-1 Calorimeter Trigger Pre-Processor. Its main feature
is a XiLinx_FPGA, which serves two purposes:
Interface via a "dual-ported" memory to VME.
Control and provide data Input/Output to/from the mezzanine cards.
Several types of CMC cards were - and are still being - built:
The CMC_dMCM, to test an essential building
block of the Pre-Processor system -- the "demonstator"
MCM
(Multi Chip Module)
The NEW, more versatile version of LVDS transmission/reception and Fanning-out.
The VME motherbords can be equipped with various configurations of CMC
daugthers. The essential difference lies in the code of the controlling
FPGA. Examples are:
a test of a CMC_dMCM delivering readout data,
which are collected by a ReM_ASIC (ReadoutMergerASIC) and passed onto the
PipeLineBus.
