Can an FPGA reprogram itself?

It would be theoretically possible for an FPGA to write a configuration image to an external memory, and load the configuration image from the memory to reconfigure itself. This would be “non-dynamic” reconfiguration.

How does an FPGA get programmed?

The designs running on FPGAs are mainly coded using Hardware Description Languages (HDL) such as Verilog, VHDL or SystemVerilog. An increasingly popular way to program for FPGA is High-Level Synthesis (HLS) in which the design is done in a subset of C and the compiler transforms the design into correct Verilog code.

Do we need to reprogram FPGA once powered off?

If you have a SRAM-based FPGA, like the Spartan 3, then you have to program it each time it is powered up. The reason for this is that the SRAM which stores the configuration is volatile and loses the programmed configuration after power is switched off.

Are FPGAs computers?

In order to program an FPGA to act like a computer from three decades ago, you have to intimately understand the original hardware. FPGAs are widely used to develop embedded systems, for example, because the software and the hardware can be designed near-concurrently.

Why are FPGAs used?

Why Use an FPGA? FPGAs are particularly useful for prototyping application-specific integrated circuits (ASICs) or processors. An FPGA can be reprogrammed until the ASIC or processor design is final and bug-free and the actual manufacturing of the final ASIC begins. Intel itself uses FPGAs to prototype new chips.

What are the different types of FPGAs based on architecture organization )?

The three basic types of programmable elements for an FPGA are static RAM, anti-fuses, and flash EPROM….Example FPGA families

• Altera Stratix II and Cyclone II families.
• Atmel AT6000 and AT40K families.
• Lattice LatticeEC and LatticeECP families.
• Xilinx Spartan-3 and Virtex-4 families.

What do you think about FPGA programming?

This is absolutely amazing, and good FPGA programmers give thanks every day for living in the rare time in history (post 1990+) when you can design architectures with words and then synthesize your logic into (mostly silicon) gates that execute your logic. Not to get carried away, but it’s absolutely wonderful.

How are microprocessor compilers used in FPGA?

Thus microprocessor compilers either produce assembly-language programs that are then assembled into bit patterns or directly produce the bits to drive the gates and fill the registers and the memories. The analogous operation in FPGA programming is the compilation of Verilog into register transfer logic (RTL) netlists.

Does the FPGA core contain only FPGAs fabric?

But FPGA core doesn’t contain only FPGA fabric since it would significantly decrease the practical applications possible. The FPGA core contains many more elements in addition to just FPGA fabric such as PLLs, Block RAMs, SerDes, Multi-Gigabit Transceivers, PCI Express blocks, DSP blocks, Configuration Logic etc.

What is the FPGA place and Route process?

The FPGA place and route process fits, in two dimensions, the bit patterns (logic subsystems) over a two dimensional array of available logic gates, and routes buses between these logic subsystems as necessary. The similarity in the processes is obvious.
