1 Uli Schäfer 1 Production modules Status Plans JEM: Status and plans

2 Uli Schäfer 2 Sum processor XC2V2000 Jet processor XC2V3000 4 input modules (IM) v1.1 (XC2V1500, SCAN921260) TTCdec module Control Module (CM) v1.3 CAN VME control Fan-out of configuration lines G-link readout module (RM) v1.2 JEM1.3 (production)

3 Uli Schäfer 3 Pre-production: 4 JEMs, 16 input modules, 4 G-link modules Yield : ~75 %, re-work and insufficient cleaning thereafter Tests concluded in first week of September Production: 41 JEMs, 160 input modules, 41 G-link modules, 45 control modules Modifications wrt pre-production modules: JEM - minor modifications : silk screen, pads for CLKdes2 terminators (due to insufficient drive strength of on-TTCdec PLL), reduce bypass capacitance on 3.3V supply (now 17*68µF) due to crate supply oscillations G-link and input modules: no modifications From pre-production to production

4 Uli Schäfer 4 September 12: pushed the button for production 3rd week of October: “Module production will take until Nov. 24” (JEM main boards), but no problems reported. October 27: “input module PCBs have been manufactured with more than 20 % impedance error”  need another production run (require 10% tolerance) October 30: PCB production JEMs and input moules (re-) started November 6: Production of input modules hasn’t actually been started yet. No information on main boards so far. Delivery of input modules will be last week of November November 8: Control and G-link modules will be ready early next week. JEM PCBs have been made. 33 out of 41 are usable and will be assembled immediately. Remaining ones will be manufactured and assembled at a later date Input module PCBs due Nov. 17, will try and have assembly done by last week in November Module production, so far…

5 Uli Schäfer 5 JTAG B/Scan ready for tests: Adapters Annotated netlist Basic link tester for input modules LVDS inputs (lock / no lock) available Basic G-link tester consisting of O/E converter + oscilloscope (fill frame) Acceptance tests

6 Uli Schäfer 6 Production crate now available at Mainz No more problems with tripleE mechanics One old VMM One old TCM no CMMs 6U crate with TTC system, one LSM, DSS For test plans see Markus presentation: LVDS tests (firmware error detection and via spy) FIO tests (firmware error detection) G-link tests (software error detection via DSS) JEM rtdp tests (including algorithms) via spy Full system tests with CMMs and ROD readout possible at CERN only… System tests Mainz

7 Uli Schäfer 7 Mid November: Mechanical assembly of JEMs (front panels etc.) Power up and test all available modules individually (boundary scan) Mount available daughters on main boards ~ Last week of November: delivery of input modules Boundary scan input modules and mount on JEMs (< 2 weeks) System tests : ~ 2 weeks (partially overlapping) Prepared to continue work on JEMs last week of December Modules at CERN early January… Plans
