I search for new mentions of ghdl weekly and found Professor Gonçalves plugin a half hour after it was published and added it to Firefox. It's useful in lieu of a site index and it's too bad there isn't more on ghdl.free.fr to find. It's view of the site is limited by the software whose search it uses. For example raw information can be found here http://ghdl.free.fr/site/uploads/Main/ I also took a look at gcg and am reminded of three things. There used to be a VHDL source editor that was also designed to teach VHDL syntax, it could be used to show where you were syntactically and what your choices were from where the cursor was. It failed in the market place, being too expensive for the time (1990 or 91) and the company went on to field an analyzer/simulator. Another is templates as used in ISE editors, closely related to the gcg effort. The third on a more personal note, I used to have a set of macros for joe (Joe's Own Editor) which I eventually gave up on after the second reorganization of macros since their inception. The macros were labor saving devices. The rest (and gcg) appear to be oriented toward learning VHDL. Today we see the majority of ghdl-discuss activity associated with tool maintenance and troubleshooting, with the occasional intersection with educational uses through the intersection of free as in software freedom, and free as in free beer. (ghdl doesn't cost anything). For instance Dr. Douglas Lyon has used ghdl in teaching digital design at Fairfield University. In this case we also see a lot of Brazilian, Argentine and South American interest in open source including EDA/CAD, enabling innovation in particular through educational institutes (see A Methodology and Toolset to Enable SystemC and VHDL Co-simulation, Maciel, Bruno Albertini, Sandro Rigo, Guido Araujo, Rodolfo Azevedo State University of Campinas - PO Box 6176 - 13083-970, Campinas, Brazil, or IP Core Mac Ethernet, Ing. Rodrigo A. Melo, Ing. Salvador E. Tropea,Instituto Nacional de Tecnología Industrial Centro de Electrónica e Informática Laboratorio de Desarrollo Electrónico con Software Libre,http://www.lacie-unlam.org/uea2010/trabajos/uea2010_submission_11.pdf (en espanol, Google Translate output is almost readable) for example, both using ghdl). Note that both UTIS INIT and Professor Gonçalves COINT UTFR are state sponsored, where the value of open source to innovation appears well recognized.
