General characteristics

Available hardware

• Altera cyclone 1 FPGA: EP1C6Q240C6N
• 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 to address decoder FPGA only. 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.
• 16 NIM outputs
• 16 NIM inputs
• 16 ECL/LVDS inputs (14 or 15 on Rev0 boards)
• 16 "red" and 16 "green" LEDs
• 1 "VME access" LED
• 1 RJ-45 high speed serial I/O interface

Firmware revisions

To find out the current firmware revision, read VME register 0, i.e. run "test_VMENIMIO32_gef.exe --addr 0xN00000 --read 0".

To write Cyclone 1 FPGA firmware into the flash memory, use a JTAG programmer or a VME programmer: "srunner_vme_gef.exe -program -64 ~/daq/VME-NIMIO32/VME-NIMIO32/VME-NIMIO32/VME-NIMIO32.pof 0xN00020", where "N" is the A24 VME base address.

To reboot the Cyclone 1 FPGA into the new firmware, run "test_VMENIMIO32_gef.exe --addr 0xN00000 --read 0 --write 1 2 --read 0 --sleep 1 --read 0", where "N" is the A24 VME base address. This requires firmware 0x01100810 or newer and the "fpga-reset" hardware modification.
