    Implementation december 2000
    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.


    Implementation january 2001
    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
