List of useful (to me) FPGA resources:

Books

• http://www.freerangefactory.org/site/pmwiki.php/Main/Books (read all three of them, first two are VHDL)

Tools

• The ideal software tool to write, simulate and synthesize your VHDL code. https://code.google.com/p/boot-vhdl/

Projects

• http://hamsterworks.co.nz/mediawiki/index.php/Main_Page (great projects)
• FPGA-BASED USB INTERFACE http://www.xess.com/projects/FPGA-USB-V2/readmeusb-v2.php
