JEM1 H/W Status

Input daughters:• 4 modules available• 2 fully working (PCB ageing problems)Main board:• 1 module available • Fully working. Few bug fixes required (2 tracks missing, 1

pull-up).• CAN under test. Compatibility ?• Flash configurator not yet successfully operated (cfg read

error)G-link daughters:• 1 (electrical) module available, in-house assembled, re-

worked after RAL test.• fully (?) working

JEM1 firmware status (energy sum / control)

• Previous JEM0 functionality fully implemented • Latency reduction (energy path) ~3 ticks• TTCdec :

• I2C control added• TTCrx ID via GeoAdd• short broadcast support

• CPM-style spy memory control (continuous spy, wrap at 255)• Playback / spy VME-controlled, use broadcast to reset pointers • Flash configurator (ACE) mapped into VME• VME control (including configuration) faster and more reliable

To be done:• Support for CAN (?)

Plans : JEM1 Prototype production

Make a total of 4 JEMs for slice test & beam test

Main board:• 3 PCBs available • Components available • Assembly at Rohde & Schwarz starting next week (?)

Input daughter modules (+16):• Active components (LVDS/Xilinx) available• Slot for PCB production & assembly at Rohde & Schwarz: ?

G-link daughter modules:• Components available • Slot for PCB production & assembly at Rohde & Schwarz: ?

Total of four JEMs available for tests early August
