VHDL, Verilog, SystemVerilog for Visual Studio.
Sophisticated IDE support for VHDL and Verilog/SystemVerilog; Supports semantic/syntax highlighting, renaming, quickinfo, code snippets, intellisense, code completion, etc.
Please visit my homepage http://www.vide-software.at for detailed information about the VHDL/Verilog/SystemVerilog code editor V3S. V3S fully supports VHDL2008, and I am continuously working to improve Verilog/SystemVerilog support as well. Just download the extension - it will work without restrictions for a 30-day trial period.
The following list provides just an overview to the most useful and powerful features of V3S. Please refer to the full feature-list for a detailed description of all features.
