TCM, GIO, CAN & TTCRx

This document outlines the modifications and improvements implemented in the TCM, GIO, CAN, and TTCRx systems. Key updates include redesigned VME display logic, extended memory for CAN, and ongoing development of software for the CPM. Critical components such as temperature and voltage readings from the CMM via the CAN bus have been integrated. Other enhancements address design issues with connectors and prepare for new schematic updates. The document also lists priorities for future revisions, testing, and manufacturing efforts for related modules.

Presentation Transcript

  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
