Types of FPGA programming modes

Question

Write down the various types of FPGA programming modes? What are you at present using? Describe how to change from one to the other?

Answer 1

Before powering on FPGA, configuration data is stored externally in a PROM or some another non-volatile medium either on or off the board. Subsequent to applying power, the configuration data is written to FPGA by using any of five various modes: Master Parallel, Slave Parallel, Master Serial, Slave Serial and the Boundary Scan (JTAG). The Master and Slave Parallel modes choosing pins can be set to choose the mode.
