=== Available hardware ===


* Altera cyclone 1 FPGA: EP1C6Q240C6N
* Main FPGA: Altera cyclone 1: EP1C6Q240C6N
* Trigger FPGA: two of the same (3 FPGA grand total)
* Serial flash for FPGA configuration: Altera EPCS16
* Serial flash for FPGA configuration: Altera EPCS16
* External SDRAM memory
* 6+6 NIM outputs
* VME interface: VME-D[31..0] bidirectional, VME-A[19..0] input only, DTACK output, no BERR, no RETRY/RESP. VME-A[31..20] input only connected only to address decoder FPGA (Altera MAX-something CPLD). This permits all single-word transfer modes, 32-bit DMA (BLT32) and 2eVME DMA (only drives D-lines, but still faster than BLT32). 64-bit DMA (MBLT64) and 2eSST are impossible.
* 2 analog outputs for calibration pulse
* 16 NIM outputs
* 2 NIM inputs
* 16 NIM inputs
* 256 LVDS inputs into the 2 trigger FPGAs (128 inputs each)
* 16 ECL/LVDS inputs compatible with LeCroy 4616 ECL/NIM/ECL converter. (Except: Rev0 boards have an incompatible ECL connector)
* 16 "red" and 16 "green" LEDs
* 1 "VME access" LED
* 1 RJ-45 high speed serial I/O interface
 
==== Firmware functions ====
 
Generic IO32 firmware can include a number of functions. Not all functions are available all at the same time due to resource limitations on the FPGA. Refer to [[:VME Registers]] for detailed information.
 
* 20 MHz 32-bit timestamp clock register
* 16 bits of NIM output register (first 4 NIM outputs are multi-function)
* 16 bits of NIM and 16 bits of ECL/LVDS input register with latch function.
* 32 scalers 32 bit, 300 MHz counting rate
* 20 MHz 32-bit timestamp clock register
* 4 timestamp registers using the 20 MHz timestamp clock. Any of the 32 inputs can be routed into any of the 4 timestamp registers.
* trigger counter, trigger timestamp functions for NIM_IN[1] and DAQ busy functions for FP_NIMOUTPUT[1].
* 20 MHz clock for VF48 ADC and VT48 TDC
* 40 MHz clock for V1190 TDC.
* example pulse generator (programmable period 32 bit 10 ns, fixed width 100 ns)
* example L222-like delay and gate generators (NIM_IN[2]/NIM_OUT[2])
* experimental 4-channel TDC. 10 ns base clock with 0.3 ns interpolation ladder (1 ns RMS).

Unless otherwise notes, because of FPGA resource constraints, firmware for Rev0 boards have 16 scalers for NIM_IN[15..0] and have no scalers for ECL/LVDS inputs. Firmware for Rev1 boards has 4 scalers for NIM_IN[3..0] and 16 scalers for ECL/LVDS inputs.

General characteristics

      1. ==== Photos ====
      3. Rev0 and Rev 1 boards

Available 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 VME programmer (srunner_vme) and IO32 test program (test_VMENIMIO32):
  • read the firmware revision from VME register 0:
    • ./test_VMENIMIO32_gef.exe --addr 0x100000 --read 0
  • write Cyclone 1 FPGA firmware into the flash memory using the VME programmer:
    • ./srunner_vme_gef.exe -program -64 VME-NIMIO32.pof 0x100020
    • !!!be careful about using Rev0 pof files for Rev0 boards and Rev1 pof files for Rev1 boards!!!
  • reboot the Cyclone 1 FPGA into the new firmware (requires "fpga-reset" mod):
    • ./test_VMENIMIO32_gef.exe --addr 0x100000 --reboot
