Nevis FVTX Status Dave Winter 8 June 2006 Bruce, hard at work.
After Bill’s “Retirement” I know of a soldering iron with Bill’s name on it… W.A. Zajc D.Winter/Columbia University
Nevis FVTX test setup • Goal: test readout concept(s) • Clockless readout • Remote data readout via fiber • Understand how to interact with FPIX • Current setup • “Proto-ROC”, “Proto-FEM”, PC, FPIX test board • Modified original Knapp test board to mate with FPIX test board D.Winter/Columbia University
Test-stand Topology “proto-ROC” PCI Card (“proto-FEM”) RAM PC Optical transceiver Optical transceiver FPGA FPGA Under construction Details of each component on slides that follow… FPIX Board D.Winter/Columbia University
FPIX Test Board • Single FPIX chip, no sensor • Receives power from proto-ROC board D.Winter/Columbia University
“Proto-ROC” Test Board One copy modified to provide connection and power to FPIX test board Motorola DSP MC56309 JTAG port for Altera • EPC2 Serial EPROM • 2 Mb 80 MHz xtal • Altera Cyclone EP1C3T144C7 • 144 pins JTAG/Debugger port for DSP Twinax connecter header D.Winter/Columbia University
“Proto-FEM” PCI Card CYP15G0101DXB serdes JTAG port for Altera 80 MHz xtal • CY7C1354B Pipelined SRAM • 256k x 36bits Altera ACEX EP1K50QC208-1 • Agilent HFBR 53A3DEM • 850 nm multimode 32-bit 33 MHz PCI standard D.Winter/Columbia University
PCI Board in action Fiber connected in loop back configuration D.Winter/Columbia University
Status • Validated concept of clockless readout from FPIX board using proto-ROC board • Samples Fast-data out from FPIX at 4x freq • Tested with fast clock of 140 MHz • BCO can be anything, most likely 20 to 30 MHz, though we don’t know the upper limit • Basic operation of PCI board established • User code on PC allows basic interaction • Read/write PCI registers, send data to PLD • Rudimentary loop back operation performed • Data read from RAM • Sent to fiber • Received from fiber • Received data written to RAM • Rates of 80 MBytes/sec achieved • PLD logic currently in a state of debugging • Layout for next generation of “ROC” board made • Sent to fabricator • Includes optical transceiver and serdes • Contains power and pulser for FPIX • Ready (fab+logic) in ~ 1 week • Complete system will enable user to send FPIX commands from the PC, get replies and data back into the PC D.Winter/Columbia University
