What is FPGA and ASIC and how each of those is used?

[fidjouss100]

can anyone tell me what s FPGA and ASIC and how each of those is used and give some real examples.

I am also looking for a saimple online tutorial for verilog.
thanks

ASIC & FPGA

FPGA---- FIELD programmable fata array. they are fittable for the product which need many times program and small chips.
ASIC --- applicational special intergrated circuit. They are fittable the product which don't modify and need a lot of chips.

this one is good for beginner.

ASIC vs FPGA is a age old debate. Anyway, when you want for example do a CDMA Receiver, there are two ways of doing it.

FPGA Way: Write the RTL Code and then synthesize to FPGA specific blocks like( macroblocks or CLBs) and use some tool to generate the Bitstream for the specific FPGA chip and then fuse it into the chip using JTAG or serial.

ASIC: You write RTL, You have to get standard cell libraries from vendors and synthesise your design to that library and then proceed till the layout by yourself using the plenty of EDA(Electronic Design Automation) Tools like Synopsys or Cadence...Then send for foundary.

The primary difference is in FPGA, you fuse your stream in a already existing chip
IN asic, you are doing your own chip. There is lot of money involved(huge!) but you can get FPGA for 5 dollars. And FPGA dont give flexibility and freq ranges. The latest FPGA might work upto 100 Mhz or so..but ASICs can be done Ghz and beyond..So the final decisive factor is Money..if you have lots...ASIC is the soln...

Hi,


Attached are the very good documents on

1. FPGA vs ASIC
and
2. Verilog

I hope this helps....good luck...

ASIC & FPGA

There have been so many discussion about ASIC vs FPGA in the forum. You can just search it and enjoy yourself.

Re: ASIC & FPGA

NRE is more for FPGA than ASIC
ASIC can work at high freequencies.

use ASIC if the code is fixed and you require more chips.
use FPGA if the code can be modified in feture & the number of chips required is less.

Re: ASIC & FPGA

There are many many articles in this board related to ASIC/FPGA, find a search on these.

But still Asic and Fpga are two different technologies

refer these for all the details of asic and fpga.

thanks for all of you. I find this site very helpful so thanks again

Re: ASIC & FPGA

You can verificate the program by FPGA.

Then you use the ASIC flow to tape out your design.
