  18. Implementation December, 2000 • Four unique types of cards • Event Tag Generator (ETG) (1) • Event Tag Generator Int. (ETGI) (4) • VBD Interface (VBDI) (8) • Serial Interface Board (SIB) (256) • SIB appeared in almost all components • VRC = VBDI + SIB • SB = ETGI + 12 SIB • Node = Motherboard + 4 SIB • SIB design nearly complete but could not be routed according to design rules. Too ambitious for form factor.

  19. Implementation January 2001 • Response: • Simplify designs by building cards with functionality limited to specific site. • Short term: • Build a SIB1 or “SIBling” with functionality only required for VRC (to be used later in ETG) • Supplement this with increased ethernet capabilities. ~100Hz • Long term: • Stage upgrade by building SIB2 and SIB3 which are more specifically targeted to SB, L3Nodes, ETG and final VRC. • Current Status • SIB1 • At vendor, 20 bare boards to be shipped between Thursday and Tuesday • Assembled, at Brown 2/22 • VBDi • At vendor today or tomorrow. • Assembled, at Brown 2/22 • Designs of other cards well along, can be derived from work with original SIB

  20. L3/DAQ Schedule • Stage1 3/22 • 50 Hz • VBDi/SIB at D0 • Ethernet upgrade • >100 Hz • Still discussing implementation • Stage 2 6/14 • ~200 Hz • Additional VRC,SB Hardware • Stage 3 7/19 • 1 kHz • Final Hardware • L3 Review Committee (Schamberger, Fuess, Blazey) reviewing design, schedule weekly March L3: 50 Hz Improving Capability
