cpld vs fpga

what is the difference between PLD, SPLD, GAL, CPLD and FPGA ?
 

fpga vs cpld

Cpld is usually used in small or middle project,
however fpga is usually used in big or huge Project.

and the Timeing in CPLD is usually easy to control whick is more different in FPGA.

and the cells in CPLD is more bigger than that in FPGA!

WHAT I KNOW IT THAT!!
ENJOY IT!
 

difference between cpld and fpga

Download this the book referred by the link:


In this book the answer of your question is explained in detail

thanks
 

difference between fpga and cpld

To designer, no difference.

I`m not agree with you.

CPLD`s and FPGA`s have absolutely different architectures.
And for effective development you MUST know how
functions implemented in chip

IMHO
 
cpld vs. fpga

There is one good article from altera..
u can search for the following title in google.com
"CPLD Vs FPGA Comparing high capacity programmable logic"

rgds,
Rajendar
 

compare cpld fpga

Vistit the websites of Altera and Xilinx; you can find a lot of info
 

cpld as rom

It seems that the input of CPLD's cell uses the configurable OR plane and the input of FPGA uses the LUT. Of cource, the gates counts of FPGA is much larger than CPLD.
 

compare fpga & cpld

I think FPGA is suited for timing circuit becauce they have more registers , but cpld is suited for control circuit because they have more combinational circuit. At the same time, If you synthises the same code for fpga for many times, you will find out that each timing reports is different.But it is different in cpld synthisesing, you can get the same result.
 

diff b/w fpga and cpld

fpga can be use to high-end product.
cpld used to low-end product
 

cpld fpga differences

hi

I think that fpga has more flexibility as well as design capacty in terms of complexcity compared to cpld. also that fpga can operate at very high speeds compared to cpld.

cpld v/s fpga

The difference b/w FPGA and CPLD are: Interconnection, programming technology and logic blocks
 

fpga cpld difference

The fpga and cpld have completly different architecture and semiconductor method. So the cpld is very hard to own more resource.
The cpld could work immediatly after power up. But fpga could not work untill the configuration is done.
 

cpld versus fpga

Hi to everyone:

Generally, the CPLD devices are not volatile, 'cos they contain flash or erasable ROM memory in all of cases. The fpga are volatile in many cases, that's way they need a configuration memory for working with programmed desing. Of course exists some variants in FPGA, one of them uses antifuse technology which makes impossible to change the configuration for new desings.

Regards.
 

diff fpga and cpld

FPGA is ram base. CPLD is rom base
 

what is the difference between fpga and cpld

FPGA are more powerful and u will get more pinouts but compare to that less logic.... but CPLD has good capacity...FPGAs can be SRAM or ANTIFUSE or non-volatile also.... but CPLDs are generally non-volatile.. nowadays ppl are using SRAM or antifuse based FPGAs which are to be programed/configure after power up thru serial or parallal eeprom... but advantage is u can reprogram it....In ckt reporgramability support will be there.

in term of cost, which is cheaper ?

Not really, there are FPGAs that are Flash (anti-fuse) based, like the ones from ACTEL.
 

difference fpga cpld

from fpga4fun.com dıfferences of fpga and cpld devices

FPGAs are "fine-grain" devices. That means that they contain a lot (up to 100000) of tiny blocks of logic with flip-flops. CPLDs are "coarse-grain" devices. They contain relatively few (a few 100's max) large blocks of logic with flip-flops.
FPGAs are RAM based. They need to be "downloaded" (configured) at each power-up. CPLDs are EEPROM based. They are active at power-up (i.e. as long as they've been programmed at least once...).
CPLDs have a faster input-to-output timings than FPGAs (because of their coarse-grain architecture, one block of logic can hold a big equation), so are better suited for microprocessor decoding logic for example than FPGAs.
FPGAs have special routing resources to implement efficiently binary counters and arithmetic functions (adders, comparators...). CPLDs do not.
FPGAs can contain very large digital designs, while CPLDs can contain small designs only.
