ATLAS Level-1 Calorimeter Trigger Hardware Progress Meeting - 02 March 1999 Minutes Present: Eric Eisenhandler, John Garvey, Norman Gee, Bob Hatley, Viraj Perera, Richard Staley. 1. ACTION list from previous meeting: a) Richard has spoken to Paul Hardy who is happy for him to continue to use the present Cadence system. Richard does not make heavy use of the system, so there is minimal impact on other users. There will be a Solaris update to address the Y2K problem, but this should not affect Birmingham access. b) Sam has sent a sketch of the Jet part of the JEP backplane. This should be discussed with Uli and Magnus at Birmingham meeting - Norman/Tony. c) Read CCM draft specifications - ALL. Retain action. d) Produce new CPM prototype schedule - Tony. Retain action. e) Bob had still not received cable information from Raychem technical experts, and will chase them. f) Richard has made some backplane measurements - See (2) below. g) Norman has prepared a draft DSS exploitation plan which should be discussed at Birmingham. h) Investigate how to get ATLAS racks on loan from CERN - Tony. Retain action. 2. CMOS/GTL backplane cards: Richard had been investigating performance of the CMOS part of one backplane test card, running in loopback mode with the returning signal distributed to three points on the board (as required in the TDR design). He showed clean eye-patterns, and had run with no errors for 3 hours, so the error rate is less than 1 in 5*10**11. The GTL parts had arrived and would be mounted shortly. A set of tests will be done including long runs and checks of the timing window. These would be complete and a report written by 12-3 1999. ACTION RS. 3. DSS system: There is no change to the time estimate of 2.5 weeks. James has completed the VHDL Xilinx design and is now doing post-layout simulations. Azmat is looking at the details of the bits in VME registers. The specification document has not been fully updated since the review, and is waiting for details from James who is still adding VME registers. In view of the urgent need to provide up-to-date information for software developers, Viraj will produce an updated interim specification immediately. ACTION VP. Bob had incorporated comments received into the G-link daughter-card design, which would be ready for checking once the termination details had been settled. [Note. This was completed in the afternoon]. Bob expected to submit to the drawing office on schedule on 3-Mar-1999. ACTION RH. Richard had incorporated comments into the LVDS daughter-card design, but also needed the termination details. Some changes in the connector pinout should be applied and checked. [Note. This was completed in the afternoon]. Richard expected to submit to the drawing office on 3-Mar-1999, and would inform Tony when this had been done. ACTION-RS. 4. ROD prototype: Viraj reported that the review of the ROD had started, but was now waiting for details on some unresolved issues including event format details. Norman reported a conversation with ARG and EE. It was clear that not enough pre-review time had been spent on the ROD module, and future reviews would have to allow extra time for this. 5. CCM prototype: Eric had bought and brought back four TTCRx modules. Viraj aid that An interim interface would be needed to the present Timing Control Module to the DSS and ROD for initial tests. The signals required were a clock and a start/stop level. This should be specified depending on what the TCM could provide. ACTION VP, RH, NG. 6. System test software status. Norman reported that Kithsiri now had a version of diagnostics with both registers and memories, and this was being debugged. It had not been tested with VME Bill Stokes was working on the DAQ, and Norman had supplied a list of the areas needing work for the DSS. Both areas urgently needed the updated DSS specification. The status of both areas will be reviewed at the Birmingham meeting. 7. AOB. None Next meeting: Tuesday 9th March 11:00 in CR1, RAL.
