i want to implement an ethernet switch on the fpga
i want to use spartan 3 board
it got 200 000 gate
would that be enough??

Re: number of gate required?

I found 'Google' something like 2100LE's in Stratix.

I assume however this will not be cost effective - unless you want a very special setup. Browsing the existing ASSP's, you'll find almost everything you need.

Re: number of gate required?

well.. before any actual implementation u shud try the synthesis which would provide you with the approximate number of gates, clbs etc etc.. nowadays CPLD are gainin popularity.. and its jes a matter of time before u can use them insted of costly FPGAs.. jes finish the synthesis and try to get the info.. then u can choose the appropriate fpga and cpld..


with regards,

Would you please let me know how can I implement ethernet swich on spartan 3 boards?
I know how to write verilog code, but I don't know how should I start!
