Several EDA websites are recommended

1. opencores. org
there are a lot of features available here. We can find the very good PLD kernel in 8051 kernel.
after entering, select a project or enter http // www.opencores.org/browse.cgi/by_category .
http://www.opencores.org/polls.cgi/list

Opencores is a loose collection of people who are interested in developing hardware, with a similar ethos to the free software movement. currently the emphasis is on digital modules called ''ores '', since FPGAs have CED ced the incremental cost of a core to approximately zero. activity is centered around the opencores web site
