Hardware

• Main FPGA: Altera cyclone 1: EP1C6Q240C6N
• Trigger FPGA: two of the same (3 FPGA grand total)
• Serial flash for FPGA configuration: Altera EPCS16
• 6+6 NIM outputs
• 2 analog outputs for calibration pulse
• 2 NIM inputs
• 256 LVDS inputs into the 2 trigger FPGAs (128 inputs each)

Firmware update procedure

• obtain and build the TTC test program from the ALPHA SVN repository (testTTC.exe):
  • mkdir $HOME/online
  • cd $HOME/online
  • svn checkout https://ladd00.triumf.ca/svn/alpha/trunk/online/vme
  • cd vme
  • make testTTC.exe
  • (Makefile may need to be adjusted to switch between the GEF_VME and the Universe drivers)

• obtain and build the VME programmer (srunner_vme):
  • mkdir $HOME/packages
  • cd $HOME/packages
  • svn checkout https://ladd00.triumf.ca/svn/daqsvn/trunk/vme (username svn, password svn)
  • cd vme
  • make -k srunner_vme.exe srunner_vme_gef.exe

• read the firmware revision from VME register 0:
  • ./testTTC.exe --ttcx --exit

• write Cyclone 1 FPGA firmware into the flash memory using the VME programmer:
  • ./srunner_vme_gef.exe -program -64 alphaTTC_0x7f120629.pof 0x410000b4

• there is no reset-mod for the ALPHA TTC module, you have to cycle the power to reboot it (reboot the Cyclone 1 FPGA into the new firmware) (requires "fpga-reset" mod):
