SLB ASIC (1)
  • Bugs of Version 4 (May 04) ? ?????
  • Timing violation at memory WRITE cycle (from L1
    Buffer to De-randomizer Buffer)
  • Any error does not appear when De-rand. Buffer is
    empty (no read-out queue).
  • Between Address and WEB 0.3ns timing violation
    is shown by the simulation, which is taking into
    account the wire length and the load after the
    layout.
  • Overflow counter of De-rand. Buffer does not
    work.
  • The start number of L1ID shall be 0, not 1.
  • Version 4-ECO (Oct. 04) ? ??
  • Modification at gate layout level on CAD
  • Additional delay (10 buffers) to clock signals
    for the address counter.
  • Improved, however the error couldnt be fixed
    perfectly.
  • The additional delay (1.2 ns) is NOT enough.
  • Large input capacitance of WEB 0.25pF
  • Skip a F/F for Overflow counter
  • The Overflow counter does work properly.
  • The bug of L1ID was not touched.

SLB ASIC (2)
  • Version 5 (Nov. 04) ? ??
  • Modification from HDL level and improvement of
    timing margin
  • The bugs of Version 4 were fixed.
  • However, DOES NOT work at 40 MHz, up to 30 MHz.
  • Serial-to-Parallel converters of read-out part
    (four 220-shift-registers) limit the speed.
  • A CLK signal from a buffer with lowest driving
    power drives 440 D-F/Fs of the S-P converters.
  • Obsolete design compiler (2000 Synopsys) was
    used, with un-proper options.
  • Careless check after the layout !

SLB ASIC (3)
  • Version 4-ECO2
  • Further modification of Version 4-ECO
  • Modification at gate layout level on CAD
  • Additional delay (20 buffers 2.4ns) to clock
    signals for the address counter.
  • Buffers in front of each WEB input port of the
    memory
  • Margin of the timing between ADDRESS and WEB is
    2.5 ns.
  • Simulation using the back-annotated Standard
    Delay Format (SDF) file
  • Except for memory write cycle (modification at
    gate layout level).
  • Read-out works at up to 70 MHz and Trigger Matrix
    up to 54 MHz.
  • Submitted 29/Nov. and chips in Feb. 05

SLB ASIC (4)
  • Version 6
  • Modification of Version 5 from HDL level
  • Design compiler (Rev. 2001 Synopsys) with proper
    option setting
  • Each WEB port of the memories is driven by an
    individual buffer (BUF6).
  • The numbers of fanouts for all signals are
    checked to be within reasonable numbers.
  • Full simulation using the back-annotated Standard
    Delay Format (SDF) file.
  • Except for INPUT BLOCK
  • Margin of data write cycle in memories is larger
    than 1.8 ns.
  • Read-out works at up to 69 MHz and Trigger Matrix
    up to 54 MHz.
  • To be submitted in 2004. Chips in Feb.
  • Mass-production takes two months. (April-May)
  • Inspection takes one month.
