  1. ECE 554 HW Tutorial Spring 2002 www.engr.wisc.edu/ece/courses/ece554.html

  2. OBJECTIVES • Hardware setup • Configuration (.bit) download • Introduction to logic analyzer

  3. Hardware setup • Probe CLK pin and ground it properly • Turn on the equipment • Make sure that all the knobs on the pulse generator are at the “black” mark • Adjust the clock frequency and read it from the scope

  4. Configuration Download Parallel Cable Serial Cable NT machine running GXSTools V.3.3 - GXSLoad - GXSPort

  5. Manuals • GXSTools V.3.3 (Being used) • GXSLoad • GXSPort • GXSTools V.4.0 (Coming soon) • GXSLoad • GXSPort

  6. Logic Analyzer: Functionality • Timing Analyzer • State Analyzer

  7. Timing Analyzer: How it works • Synchronizes with target CLK • Samples every 1/fs = 2n *4 ns, n=0,1,.. • It has limited amount of storage • Samples with a transition detector • Set the right fs for your signals

  8. Sampling at high resolution

  9. Sampling with a transition detector

  10. Triggering on events

  11. State Analyzer: State Trigger

  12. State Trigger

  13. State Analyzer: Hex codes translated into assembly code

  14. MSBs LSBs Left Right 19-bit addr 512 k words WEB OEB 32-bit data SRAM Loader

  15. Logic Analyzer and XSV Board Pod A[15:0]=Data[31:16] Pod B[15:0]= Data[15:0] Pod C[15:0]=Addr[15:0] D[0]=CLK,D[1]=WEB,D[2]=OEB
