3 Progress up to date Acquired software and licence for Allegro ConceptHDL Acquired software and licence for Allegro ConceptHDL – Design flow established – The first run slightly slow – improved for others – Schematic design and packaging at UCL – Layout at RAL Test card A design Test card A design – Schematic entry/layout finished – Named PC3461M – In the manufacturing and assembly stage RTM design has started RTM design has started – Schematic entry started xTCA crate has been purchased xTCA crate has been purchased – Set up and running with SLC

4 Progress up to date Firmware design on the development platform Firmware design on the development platform – Telegram transmit/receive – FAST message transmit/receive – Test Bench Firmware comprising all transmit/receive blocks Firmware comprising all transmit/receive blocks Transmit can be started by external input (push-button or ChipScope VIO) Transmit can be started by external input (push-button or ChipScope VIO) Results can be observed by ChipScope Results can be observed by ChipScope – PCIe Development card can be accessed through PCIe Development card can be accessed through PCIe – Manual start/stop (standalone operation)

5 Hardware Structure PCM3461 Assembly drawing top and bottom sides RECEIVE TRANSMIT Test / Prototyping area

6 Hardware Structure PC3461M to be used for PC3461M to be used for – FAST message transmit/receive testing (via ETH cables) – Telegram message transmit/receive testing – Available for others to use (with the XUPV5 development board)

7 Hardware Structure Prototype RTM to test with the DAMC2 board in the xTCA crate Prototype RTM to test with the DAMC2 board in the xTCA crate – Early prototype availability for the system – Diagnosing bugs/gotchas with the design – Later revision to add more capability – Prototyping platform for extra features if needed for extra features if needed – Tests to be carried out in the actual setup (xTCA crate) in the actual setup (xTCA crate) RJ45 CONNECTORS (8/16) LVDS DRIVERS LVDS RECEIVE CLOCK / PLL I2C / EEPROM POWER

8 Firmware Structure A test firmware that integrates transmit/receive and other features A test firmware that integrates transmit/receive and other features – One bit file to program the FPGAs on the dev boards – ChipScope cores associated with each block Firmware diagram – Finished blocks + extras for test Firmware diagram – Finished blocks + extras for test Clocking implemented according to the dev board Fast Message Receive implemented as a part of LPD FEM firmware Telegram transmit implemented for TR Buttons on dev board

9 Telegram transmit/receive Telegram transmit/receive Two packet structures for data and events Start Byte (x2C) + Write_Type + CRC (for events) Start Byte (x2C) + Write_Type + CRC (for events) Start Byte (x2C) + Write_Type + Data (32-bit) + CRC (for data) Start Byte (x2C) + Write_Type + Data (32-bit) + CRC (for data) WR_CLK can be different than 108 MHz ASYNC FIFO in the transmitter ASYNC FIFO in the transmitter FLAG_OUT indicates types of events and data 8-bit CRC IDLE pattern (x5885) sent between packets Firmware Structure BUNCH_PAT_ID TRAIN_NO_OUT FLAG_OUT (event/data) CLK_OUT (27 MHz) TEL_CLK_OUT TEL_DATA_OUT CLK108 WR_TYPE WR_DATA WRITE_CLK WR_EN TRANSMIT RECEIVE TRCC SIGNAL DIAGRAM FOR TRANSMIT INPUT
