US Status of GbE Peripheral Crate Controller Ben Bylsma EMU meeting Fermilab, October 21, 2005 Section 1: Hardware Section 2: Firmware Development

B. Bylsma EMU Meeting, Fermilab Oct. 21, Hardware Status 10 Pre-Production Boards  5 at CERN (2 returning)  1 at Rice  3 at OSU  1 in DMB/DDU/DCC test setup  1 for Firmware Development  1 Problem Board (unsolved)  1 at UCD Radiation Test “Real World” Experience  OSU  Rice  B904 No Issues Reported 75 Production Boards in Hand Scheduled to be Stuffed Pre-Production Version

B. Bylsma EMU Meeting, Fermilab Oct. 21, Radiation Testing 63.3 MeV Proton Beam at Crocker Nuclear Laboratory (UCD)  Irradiated all active components not previously tested.  Main goal was TID for survivability (not SEUs).  Exposed components to ~6 kRads. (exp. Max. ~.13 kRads) Results:  Boring. Mostly uneventful.  Most failures recovered with reset (some need power cycle).  All components survived. SEU mitigation:  Reset circuit uses discrete logic and majority voting.  Data stored in FIFOs and FLASH uses ECC and majority voting.

B. Bylsma EMU Meeting, Fermilab Oct. 21, PCBs produced Stuffing:  All components and PCBs at Dynalab for one month.  Dynalab given OK to go, but are overloaded with jobs.  Stencil is due Monday.  Surface mounting run to start next week.  Expect delivery of stuffed boards within two weeks. Testing and Delivery:  ASAP after delivery of stuffed boards. Production Status Production Schedule

B. Bylsma EMU Meeting, Fermilab Oct. 21, Firmware: What’s New Firmware Revision 3.06  Programmable MAC address.  Device MAC address.  3 Group MAC addresses.  Default Server MAC address.  Access to configuration registers.  Storage for up to 21 different configurations in FLASH memory.  Settable default configuration (for power up).  New format of returned packet data headers.

B. Bylsma EMU Meeting, Fermilab Oct. 21, New Data Header Format Returned Packet Data Header:  Prior to Rev. 3:  As of Rev. 3

B. Bylsma EMU Meeting, Fermilab Oct. 21, Firmware: What’s Next Need for Feedback  One at a time reads (built in feedback/data is expected)  One at a time writes (when does command finish?)  Stacked reads/writes in FIFO (when is FIFO almost full?)  Particularly a problem for programming PROMS with several MB of write commands. Developing two methods for feedback.  Warning packets ( Error and Info packets as well ):  Spontaneously generated packets when certain events occur (like when the “almost full” flag of the external FIFO is set).  Spontaneous packet sending can be enabled or disabled.  Acknowledgement Requests.  Bit in header of every packet sent.  Return packet with disposition of corresponding command.  Under programmers control on packet by packet basis.

B. Bylsma EMU Meeting, Fermilab Oct. 21, Firmware: What’s Next Need for Easy Firmware Updates  Currently must use IMPACT to program PROM through JTAG.  Need to program PROM via Ethernet packets to JTAG interface.  Handshaking scheme needs to be in place. Next Revision Release  Handshake mechanism (acknowledgements and warnings)  PROM programming
