Is there a free Verilog simulator?
There is a free, copylefted Verilog simulator called “vbs”, written by Jimen Ching and Lay Hoon Tho as a senior design project in the electrical engineering curriculum of the University of Hawaii, College of Engineering. It is available from the archive at: • FTP: ftp://ftp.siliconlogic.com:/pub/comp.lang.verilog/vbs-1.3.0.tar.gz It appears that Veriwell/386 and Veriwell/Sparc are now shareware. Use is free for source files under 1000 lines. For larger files, a hardware dongle is required for the MS-DOS version, a license for the Sparc version. The simulator is available for downloading from the Wellspring Solutions BBS or via ftp: • BBS: 1-508-865-1113 (8-N-1) • FTP: ftp://iii.net:/pub/pub-site/wellspring/ InterHDL also has shareware version. Eli Sternheim says “This is a full Verilog simulator with the following exceptions: no PLI, specify blocks are ignored, no switch level constructs but gates and primitives are supported. Also there is a size limitation on the design.” • FTP: ftp:
