Dear, comment allez vous? I am a PhD student at UFRGS, Brazil ( www.inf.ufrgs.br). I am intending to develop a simulator for computer architectures and I intend to have VHDL as the entry language for the construction of the needed simulation models. Well, if I try to develop a VHDL compiler and simulator I'll use most of the time of my PhD course with this task. So I am sending this message to know if YOU HAVE A VHDL COMPILER AND SIMULATOR ( THE SOURCE CODE OR LIBRARIES) THAT I CAN USE TO DEVELOP MY SYSTEM?? Very thanks, Au revoir, Sandro Neves Soares.
