3. CPT week May 2003Dominique Gigi CMS DAQ PCI connector 64-bit FRL Function IN_1 IN_2 IN_3 IN_4 FPGA Compact PCI 32-bit 33MHz Memory 4Mbytes Commercial Optical Link Myrinet Lanai X Compact PCI Back-plane 64kB 64b@100MHz PCI 64b @ 66 or PCI-x 64b @ 100MHz 64b @ 66 or 100MHz Bridge FPGA

4. CPT week May 2003Dominique Gigi CMS DAQ CompacPCI CompactPCI bus 32bit@33MHz Internal PCI bus 64bit 66MHz -Connector for NIC board -FRL FPGA -Bridge FPGA (32-bit) 2 Inputs -LVDS receivers -Buffers 64Kbytes -Connector for 2 other Inputs -FRL FPGA SRAM memory (4 Mbytes) -FRL FPGA -Memory -Bridge FPGA Place for the NIC board PCI short form factor

5. CPT week May 2003Dominique Gigi CMS DAQ SLink64 protocol Altera ACEX LVDS Generate 3 frequencies: -40MHz from 10 to 15 meters -60MHz from 5 to 10 meters -80MHz <= 5 meters 1 switch to choose the frequency

6. CPT week May 2003Dominique Gigi CMS DAQ FRL Compact PCI backplane (32b@33Mhz) Myrinet GIII FED emu. 32 MB for Event parameters -Event # - Bunch # - FED# - Size - Time before next Event(x100ns) Myrinet board emulated by GIII to check data and header

7. CPT week May 2003Dominique Gigi CMS DAQ Generic III PCI 64bit/66MHz CompacPCI GIII: -Sends event through the cable until backpressure -Sends memory address blocks -When data is coming: Checks Event data blocks and Headers FRL -Data input through Connector -Data is sent to GIII in packets + Headers Trans.

8. CPT week May 2003Dominique Gigi CMS DAQ FRL to ZBT memory -1 to 1024 event(s) to spy -All event to spy Bridge/FED-kit reads data from ZBT memory and sends to PC memory (Fed-kit simplify) When ZBT memory is full - a status is added at the end (when 1 to 1024) - backpressure ( acquisition mode ) (when all spy) FRL Bridge / “Fed-kit” ZBT FRL Bridge/ “Fed-kit” Myrinet ZBT PCI CPCI Events

9. CPT week May 2003Dominique Gigi CMS DAQ GIII FED emul. Altera ACEX 60MHz GIII FED emul. Altera ACEX 60MHz FIFO 32kB FIFO 32kB FRL ALTERA Stratrix Myricom -first test will be done with a GIII to replace the Myrinet board Events Spy Events

10. CPT week May 2003Dominique Gigi CMS DAQ 1.Use three GIII for merger test (2 FEDs emulator-1 Test data) 2. Go to PCI –x 100 MHz 3. Correct the schematic for next production 3bis. Extender to two additional Inputs 4. Introduce the NIOS processor inside the FRL FPGA GIII FRL

11. CPT week May 2003Dominique Gigi CMS DAQ 1.All parts of the PCB are tested 2.Main functions of the FRL are tested 1.Acquisition on each input 2.Spy mode through SRAM 3.PCI 64b-66MHz 4.Mezzanine transmitter board 3.Start to evaluate the cable length (3M cable) 1.5 meters (80 MHz) 2.10 meters (60 MHz) 3.15 meters (40 MHz) 4.Pending test the maximum frequency for each length 4.Pending 1.test the 100 MHz frequency for PCIx 2.test with Myrinet board 5.Full test for June (ready for production)
