E. Hazen -- Upgrade Meetings1 AMC13 Project Development Status E. Hazen, S.X. Wu - Boston University

E. Hazen -- Upgrade Meetings2 Introduction AMC13 specs agreed by most interested parties As detailed in MicroTCA WG document Design Overview Management functions Open issues Status and plans

E. Hazen -- Upgrade Meetings5 Management Functions MMC: Minimal requirements. Prefer Atmel AVR. No space for mezzanine card  Power control; bootstrap selection for FPGA firmware Firmware: Initial bootstrap via JTAG on front panel  Loads firmware for Spartan-6 with simple GbE endpoint  Could also be done over IPMI if speed is sufficient Further firmware loads over GbE via MCH1 Select simple firmware via IPMI when required

E. Hazen -- Upgrade Meetings6 Hardware Issues – Tentatively Settled DAQ Interface Should we switch to SFP+ now? Yes... quad SFP+ is used on GLIB and should fit OK. Keep GTX SERDES. If 10Gb/s is needed, future upgrade (before 2017) TTC Interface Various ideas for upgrade on the table; none is directly compatible with current hardware. Keep current home- brew TTCrx and provide spare SFP+ for upgrades. MMC 0n AMC13. Will adopt a reference design, likely either DESY/CPPM/CERN or Wisconsin, based on Atmel uC.

E. Hazen -- Upgrade Meetings7 Status and Plans Design Underway Most issues regarding interface with rest of CMS settled... need to be sure we are all set with the uHTR First prototype hardware could be ready by May 2011 and there are at least two non-hcal users ready to start testing boards (Imperial College, Wisconsin)  Likely to be funding limited :( Firmware Development Many options here... depends on users  BU is committed to developing HCAL firmware  Trigger users may well develop their own... this is fine
