What do you need to know about FPGAs?
FPGAs belong to a class of devices known as programmable logic, or sometimes referred to as programmable hardware. Essentially, an FPGA doesn’t do anything itself but it can be configured to be just about any digital circuit you want. The magic here is that nothing physically changes.
Where is configuration data stored in Altera FPGAs?
During device operation, Altera FPGAs store configuration data in SRAM cells. Because SRAM memory is volatile, the SRAM cells must be loaded with configuration data each time the device powers up. After the device is configured, its registers and I/O pins must be initialized.
Can a FPGA be reconfigured to behave like another circuit?
No soldering, no jumper wires, no fuss. An FPGA can then be reconfigured to behave like another circuit, and another, and another. The configuration is RAM based which means it can essentially be reconfigured an unlimited number of times.
How many times can a FPGA be programmed?
SRAM based FPGAs can be programmed as many times as necessary. There is no limit until the device gets damaged by out-of-spec conditions such as voltage, temperature etc. Certain Flash-based FPGAs may have a very specific max programming cycle endurance.
Working in the FPGA industry for 2 years, I always learn something new every day. To really learn FPGAs well, you really gotta start with the very basics. Logic blocks/designs, and then translate those basic blocks into HDL (Hardware Descriptive Language) code.
Do you want to learn FPGAs SparkFun Electronics?
To make getting started easier, the Alchitry Au board has full Lucid support, a built in library of useful components to use in your project, a A Getting Started Guide and a debugger! See the bottom of this post for SparkFun’s FPGA product offerings. Learn more about FPGA with this new resource page!
How are FPGAs used in digital logic class?
FPGAs are a totally different beast when it comes to programming. I learned the basics in my Digital Logic class using the Altera schematic editor. This lets you drag and drop in basic logic blocks and wire them together.
Which is the best way to learn a FPGA?
To really learn FPGAs well, you really gotta start with the very basics. Logic blocks/designs, and then translate those basic blocks into HDL (Hardware Descriptive Language) code. From here, it’s not really about learning the FPGA itself, but more on the software that you need to use the program the chip.
