  1. TCM, GIO, CAN & TTCRx Adam Davis

  2. TCM • Modifications and Improvements • VME display logic have been re-designed. • Displays VME data of other modules. • Extended memory for CAN. • Document produced for up-dating TCM CPLD code. • Can be downloaded from the Firmware page of TCM:-http://www.te.rl.ac.uk/esdg/atlas-flt/ • Three modules in use, three to be updated and tested

  3. GIO • One design for Rx, Tx in LVDS, Bus LVDS, CMOS, etc • BusLVDS (transceiver) used to test CMM (no differential assembly required, same for Tx and Rx) • Modifications being made to design. • Incorrect CMC connector orientation • Other minor improvements • Into drawing office by the 28/10/02 for layout • Order four boards ?? • CMM tests (BusLVDS, BusLVDS-> LVDS to CMOS board) • CPM tests (BusLVDS-> LVDS to CMOS board) • TTCvi ‘sequencer’( ?)

  4. CAN • TCM requests temperature and voltage readings from CMM via the CAN Bus (CAN Remote Request). • CMM obtains FPGA temperatures via SMBus protocol & voltages using AtoD converters. • CMM also alerts(CAN Transmit) TCM that over-temperature (FPGA too hot) alarm has been set. • Software for CPM in development (1/4 way to completion).

  5. CAN • Values into TCM via CAN, then read via VME and displayed on PC

  6. CAN • How to demonstrate TCM-DCS in Slice test? • Use commercial PCI CANBus card (CAN OPEN)? • Next iteration of TCM to have CERN ELMB module? • Interface TCM Dual-port RAM via ELMB’s digital I/O • Use CAN micro-controller internal RAM and interface to ELBM via serial interface

  7. TTCRx • PROM • Obtained verilog file. • Compiled using ModelSim. • Ready for testing. • Update schematics for new TTCrx chip

  8. Summary • TCM - Display Problem solved. • GIO - Successfully being used with CMM. • CAN - ‘functional’ • TTCRx - Ongoing.

  9. Things to do In priority order: • Update GIO schematics ready for version II. • Update TTCRx card schematics for new decoder chip. • Test TTCRx cards. • Complete CAN software for CPM. • Three TCMs to be updated • TCM-DCS interface? • Manufacture, assemble and test more G-Link Rx, Tx cards for DSS/ROD ??? • Update and re-test all DSS modules
