1. ATLAS HSIO DEVELOPMENT BOARD TESTING An Overview and Test Summary of High Speed Input/Output Boards Lawrence Carlson August 10, 2010

2. ATLAS HSIO Development Board Testing Page 2 Acknowledgments Testing completion based on the collaborative efforts of several individuals –Dave Nelson –Martin Kocian –Matthew Weaver –Su Dong

3. ATLAS HSIO Development Board Testing Page 3 Work Overview Establish familiarity with testing protocols –Write manual for testing procedure Documentation –Summary –Repair Log –Individual procedure results / measurements Make documentation available to developers –Web-based proposal

4. ATLAS HSIO Development Board Testing Page 4 HSIO Test Areas

5. ATLAS HSIO Development Board Testing Page 5 HSIO Untested Areas

6. ATLAS HSIO Development Board Testing Page 6 HSIO Board Features XILINX Virtex 4 32 MB DDR SDRAM General Purpose Rotary Switch USB 1.0 & 2.0 interface chips 4-character x 2 LED display 10/100/1000 Ethernet Mac-PHY transceiver On-board power supplies for all necessary voltages

7. ATLAS HSIO Development Board Testing Page 7 HSIO Board Features Power Indicator LED Two SFP+ giga-bit fiber interfaces One SFP+ giga-bit interface One XFP giga-bit fiber interface Two AFBR giga-bit interface XILINX XCF32P Platform Flash storage device (PROM)

8. ATLAS HSIO Development Board Testing Page 8 Testing Observations Twenty-seven boards ordered –Two types FX60 (25) FX100 (2) –One FX60 shipped unloaded Testing discrepancies between LINUX and Windows –Failures in LINUX passed in Windows Drivers? –Variance between LINUX installs FX100 contains more logic cells, I/O Pairs, configuration memory bits.

9. ATLAS HSIO Development Board Testing Page 9 Test Protocol (breakdown) Resistance checks –Pre-test Voltage checks –Across on-board chips Component checks –Bit files downloaded via dongle to XILINX FPGA Documentation

11. ATLAS HSIO Development Board Testing Page 11 Test Results (Initial Testing) FX60 –Twenty-four failures Voltage short (3.3V pin) x 1 – Testing Halted Pin Wiring (P5 and J26) x 1 Ethernet port indicator lights x 23 –Quantity of failures suggest fundamental flaw »R151 resistor misplaced FX100 –Two Failures* USB 2.0 communication DDR memory read/write *- Perhaps due to bit file compilation (different from FX60) R151 resistor placed in the R153 slot. Swapping locations resolved Indicator light issues.

12. ATLAS HSIO Development Board Testing Page 12 Post-test Failures Reset switch (SW1) – 2 boards –Required manual wiring SW1 to U2 port 1 PROM program failure –Inconsistencies in PROM programming under LINUX, even after initial pass –No such issue with Windows SFP+ Ethernet port failure –Swapping Ethernet inserts for optical fiber inserts yields success test Suggest an extended burn-in time to isolate additional post-test failures

13. ATLAS HSIO Development Board Testing Page 13 What Next? Finalize manual (version 1.1) –Image/diagram insertion –FT_PROG_1.9 documentation Update test sheet documentation Consolidate documentation into web-based format –User's Guide –Testing Protocol –Test Data Sheets –Summaries –Test files (?)

14. ATLAS HSIO Development Board Testing Page 14 Things to Consider Hosting of files? –Currently residing http://www.slace.stanford.edu/~lcarlson/hsio http://www.slace.stanford.edu/~lcarlson/hsio –Static location Bit files availability –Potential issues with support –Include drivers with recommended installation instructions Testing of final (27 th ) board –Update of index.html –Inclusion of documentation
