Many other tools are listed on the eedesign Web site: www.eedesign.com/resources/opensourcelinks.html [1]. And others on the Hamburg VHDL archive: tech-www.informatik.uni-hamburg.de/vhdl [2]. One more great VHDL page: www.angelfire.com/electronic/in/vlsi/vhdl.html [3]. Also look at the comp.lang.vhdl newsgroup.
