Configuration Of FPGA

--- Quote Start ---

i am new to FPGA. i am developing hardware using EP2C5T144C8 FPGA but i don't know about the configuration of FPGA. why we need to configure FPGA.

FPGA configuration information is stored in volatile memory (SRAM). When the power is first applied, the configuration needs to be loaded, eg., like booting a processor.

what we need in hardware for configuration.

There are several different options discussed in the data sheets for the devices. If you're building a board with just an FPGA on it, then you will likely want to use Active Serial (AS) configuration from a serial flash.

i am using USB BLASTER for programming.

A USB-Blaster programs the FPGA SRAM cells directly. If you cycle the power, then the FPGA comes back alive blank, and you have to program it using the USB-Blaster again. If you add serial flash to the design, then the FPGA can be programmed from the flash at power-on. You can change the design programmed into the flash using the USB-Blaster.

what other things are required to develop FPGA Dev Board ??

Hardware:

* FPGA + power supplies + JTAG header + serial flash

Software (free):

* Quartus II web edition

* Modelsim ASE simulator (for checking your code before using hardware)

Try and figure things out for yourself, and then ask questions on this forum.

Cheers,
