1. FPGAs and IRRADIATED FPGAs for the LHCb UPGRADE Bin Gui, Ray Mountain

2. Communication  Communication  Data line  Sending 8-bit pattern to FPGA through TNG-5, then the data being shifted out and back to the PC.  Since we are using LabView to control and generate the data, the frequency is just 32Hz.  Control line  To check the FPGA’s status and get response from it.

3. Hardware

4. Core TTL LVDS TNG-5 A3PE Eval Board Transition Board PC Router IP JTAG USB FlashPro3

5. Handshaking  To found the communication between FPGA and PC, it includes three parts:  Control program (LabView)  Hardware (Mapping the ports, connect all devices, etc)  Firmware (Configuring FPGA)

6. Control Program (Front Panel)

7. Command Table (HEX) Sending from PC Meaning of the command Response from FPGA Meaning of the response AA Status of the FPGA ABOK AE Don’t Understand and Please Repeat BAStart SEU test ACBUSY BDSend Result ACBUSY …………

8. Firmware (FPGA configuration) Not finish, need to be modified. 1 2 3 4 4 5 6 7

9. To do list  Finish the work of communication between FPGA and PC.  Soldering transition board.  Memory, static register, etc.  SEU test  Irradiation test

10. Backup - PLL 200MHz (by PLL)350MHz (by PLL) 40MHz (oscillator on the board) The clock is LVTTL signal, but observing from the waveform, the amplitude varies a lot. ?
