Hardware interview practice
Choose an FPGA Configuration Mode
A board must boot its FPGA automatically from an attached serial flash with no external processor. The chosen FPGA family supports JTAG, master SPI, and slave serial configuration. Which mode best matches the requirement?
Choose one
Answer choices
- A. SelectMAP slave with no external controller, because parallel modes create their own configuration data.
- B. Master SPI, because the FPGA supplies the configuration clock and reads its bitstream from the serial flash after power-up.
- C. Slave serial, because the FPGA must always generate the clock when it is called a slave.
- D. JTAG only, because autonomous nonvolatile boot cannot use a serial flash.
