FAQ

What is the primary FPGA device on the EK-U1-KCU105-G-J evaluation board?

The EK-U1-KCU105-G-J features the XCKU040-2FFVA1156 Kintex UltraScale FPGA, a high-performance, cost-optimized device with 443,200 logic cells, 2880 DSP slices, and 96 GTY transceivers capable of 32.75 Gbps operation. This FPGA is pre-configured with Board Self Test firmware and serves as the central processing and interface hub for all on-board peripherals and expansion connectors in the EK-U1-KCU105-G-J.

Does the EK-U1-KCU105-G-J include a licensed version of the Vivado Design Suite?

Yes, the EK-U1-KCU105-G-J includes a node-locked and device-locked Vivado Design Suite: Design Edition license voucher redeemable at www.xilinx.com/getlicense. The license is bound to the XCKU040 device on the board and enables full synthesis, implementation, and debugging capabilities - essential for developing custom logic, integrating IP cores, and validating timing closure on the EK-U1-KCU105-G-J.

What high-speed serial interfaces are supported natively on the EK-U1-KCU105-G-J?

The EK-U1-KCU105-G-J supports PCIe Gen3 x8 via its M.2 edge connector, dual 10 GbE SFP+ ports with included optical transceivers, and HDMI 1.4 TX/RX using the ADV7511 codec. All interfaces are electrically validated and mapped to dedicated GTY transceiver quads on the XCKU040, enabling direct evaluation of serial protocol stacks without external level-shifting or retiming on the EK-U1-KCU105-G-J.

How does the Board Self Test function on the EK-U1-KCU105-G-J?

The Board Self Test on the EK-U1-KCU105-G-J runs automatically after pressing SW4 (PROG_B) and validates critical subsystems: Clock (PLL lock status), DDR4 (memory initialization and pattern test), BRAM (on-chip memory integrity), Flash (QSPI configuration storage), I²C (temperature sensor and EEPROM communication), plus user-interactive tests for DIP switches, pushbuttons, and rotary encoder. Each passing test illuminates its corresponding GPIO LED on the EK-U1-KCU105-G-J.

Is the FMC connector on the EK-U1-KCU105-G-J compatible with both LPC and HPC mezzanine cards?

Yes, the EK-U1-KCU105-G-J features a 72-pin FMC-HPC connector that supports both LPC and HPC mezzanine card standards. It provides access to 10 GTX transceivers, 64 user-defined single-ended I/Os, and dedicated 12 V/3.3 V/1.8 V power rails - enabling high-bandwidth interfacing with ADC/DAC, RF, or processor daughter cards while maintaining signal integrity across the full 2.5 GHz bandwidth supported by the EK-U1-KCU105-G-J's UltraScale FPGA fabric.
