The interviewer often ask about the FPGAs boards you are currently using or frequently used.
The following is an example about what answer we expected:
I’ve been used multiple product series from Xilinx and Altera:
- Spartan is a 45nm technology low-cost FPGA
- Virtex is a 28nm technology one
- Zynq incorporates dual-core ARM processor on the the same die with Artix-7 series.
Currently, I’m using a ZedBoard which contains an Xilinx Zynq-7000 AP SoC XC7Z020-CLG484
- Dual-core ARM Cortex-A9 @ 667Mhz
- Memory:
- 512 MB DDR3 Memory
- 256 Mb Quad-SPI Flash
- 4GB SD Card
- Onboard USB-JTAG Programming
- 1Gbps LAN Ethernet
- USB OTG 2.0 and USB-UART
- PS & PL I/O expansion
- HDMI output
The Zynq-7000 XC7Z020 FPGA contains:
- 85k logic cells
- ~1.3 million ASIC gates
- 53,200 look-up tables (LUTs)
- 106,400 flip-flops
- 560 kB of BRAM organized to 140 units, each containing 2048 by 18-bit storage
- 220 DSP slices (Multiplier-Accumulator) organized to 18×25
- 276 GMACs
