Kintex7 XC7K160T-2FFG676 |
The HiRADDA set is composed of two or more boards :
- HiRADDA Core
- HiRADDA Power
- n x user extension boards
HiRADDA is compatible with the FPGA Rack Backplane for interconnecting different boards with the help of the HVME16/32 version of the HES-SO Backplane Bus and the HES-SO VME IP Core.
Core features

Power supply considerations
The following power rails are produced on board :
- -A5.0V - Optionnal, for AOP input range extension
- +A5.0V (ADS1675)
- +D1.0V (FPGA Core)
- +D1.8V (SSRAM I/Os + FPGA BANK)
- +D2.5V (SSRAM + FPGA BANK)
- +D3.0V (ADS1675 + FPGA BANK)
- +D3.3V (VME + FPGA BANK)
VME connector logic levels
The I/O bank which interfaces the VME connector can be 1.8V, 2.5V or 3.3V depending on the jumper XXX position. Be careful with other FPGA Rack boards different voltage configuration.
Programmation
The FPGA on this board can be programmed in 2 ways :
- directly through JTAG interface.
- automatically on boot via the onboard FLASH memory (SPI x1/x4).
More explanation for FLASH programmation are available here.
Known issues
- None yet.
