FEE Electronics progress Mezzanine manufacture progress FEE64 testing and VHDL progress Test mezzanine. Trial mechanical assembly 10th November 2009

Mezzanine manufacture Progress 10th November 2009 PCB design sent to manufacturer Order for assembly placed and parts purchase started. PCB manufacture error requires restarting the build. Expect PCB this week. Assembler planning sequence broken – hard to predict delivery until pcb arrives. Two of the failed pcbs delivered to use for mechanical checks. ERNI connector mounted – pcb too large – manufacturer will change by 1mm overall Plan to send one pcb to wirebond engineers.

FEE64 testing and VHDL progress Assembled boards delivered. Power supplies tested and found to be working OK after a couple of wire mods. FPGA programmed through JTAG port. Two misplaced devices removed and re-fitted Flash memory programmed and used to program the FPGA. 10th November 2009

FEE64 testing and VHDL progress 128MB SDRAM operating successfully Gbit ethernet functions at 10/100/1000 Mbits/s Linux loaded over the network after the core loaded by JTAG. Loading from Flash memory not functioning yet. Some ethernet problems solved by damping capacitor. Ethernet rate tests => 10MB/sec 10th November 2009 Started testing the multiplex readout ADC. First results using MIDAS and TCL scripts. 100mV input via the test mezzanine. VHDL for timestamped ASIC driven operation in progress.

FEE64 testing and VHDL progress Test system 10th November 2009 Test mezzanine Power supplies ( +30v, -5v) DC source

Clock distribution Schematics for four way clock distribution box entered. Pcb layout to proceed after VHDL for acquisition complete. Designed for manufacture locally. 10th November 2009 FEE64 (sync master) FEE64 Clock box 200Mhz clock and SYNC distribution Master SYNC to clock box

Test mezzanine Two assembled boards delivered 4 th November. In use in T9 to exercise the multiplex readout ADC. 10th November 2009

Trial mechanical assembly Plastic versions of the FEE mechanics created by a ‘Z’ printer. Two FEE64 cards and two mezzanine scrap boards assembled. Some alterations to the spacer required. 10th November 2009
