This document presents an update on the GCT Muon Auxiliary Card, detailing its design and testing status as of October 28, 2009. The card features connectivity through SLINK-64, TTC, and TTS in a μTCA form factor, utilizing a Xilinx Virtex-5 FPGA. Design verification has been completed for TTS, S-Link, and Rocket I/O interfaces, with ongoing TTC checkout. Comprehensive testing on initial boards has shown robust performance, including zero errors over extensive data runs. Firmware development is nearing completion, with a test program embedded in the hardware for ease of testing.

Transcription de la présentation

  1. CMS Calorimeter Trigger • GCT Muon Auxilliary Card Update • Tom Gorski, • Amin Farmahini-Farahani • University of Wisconsin • October 28, 2009

  2. GCT Muon Aux Card Update RS-232 AMC Edge Connector (µTCA) TTS Pushbutton Reset (for Microblaze) S-Link Connectors TTCrx

  3. GCT Muon Aux Card • Provides SLINK-64, TTC and TTS Connectivity in a Single-Width, Full-height μTCA form factor • Xilinx Virtex-5 FPGA (XC5VLX110T) • 16 Rocket I/O GPT Links to edge connector • 1136-pin BGA Package • For connecting a μTCA crate to the TTC and DAQ subsystems

  4. GCT Muon Aux Card Update • Testing Status: Design verification completed on TTS, S-Link, and Rocket I/O Interfaces. TTC checkout is in process • Testing performed on original 2 boards. More boards to be built after design verification completed • Boards will be shipped with a test program burned into Flash—connect via RS232 port/terminal • Test software/firmware should be completed by end of 2009 • Firmware is a HDL/Microblaze hybrid

  5. GCT Muon Aux Card Update Two Aux Cards in Test Fixture Running a GTP Link Test (6 connections—4 passive, 2 through switches)

  6. Aux Card Rocket I/O Testing • Link rate of 3.125 Gbps from 125.0 MHz oscillator • 8b/10b encoding, 16-bit parallel interface (156.25 MHz parallel clock) between GTP tile and FPGA fabric • Simplex connection between Transmitter and Receiver • Uses comma (K28.5) char for sync/byte alignment • Test Protocol: 32-byte header contains ID of Xmtting board/channel, test pattern descriptor • Rcvr compares incoming data stream to that specified by header, capturing/counting errors • X/R test blocks in HDL, run independently of processor • Some results using 64-bit LFSR pseudo-random pattern: • Single board loopbacks to different GTP Tile: continuous run of 5×1015 bytes with zero errors (~280 hrs on 16 simultaneous ch.) • Board-to-Board on Slots 0 & 3 of Test Fixture: over 2×1014 bytes with zero errors (~24 hrs on 6 channels)
