Raw "V" image file created by ppmtoyuvsplit, a Unix-based program used to split Portable PixMap images (.PPM files) into .Y, .U, and V files; stores the "V" chrominance, or color, component for the image; may be restored back to the original PPM file using the yuvsplittoppm utility.
Source code file written in the Verilog hardware description language (HDL); most commonly contains Verilog 2005 source code, but may also use one of the other Verilog standards, which include Verilog-95, Verilog 2001, and SystemVerilog; used for specifying models of electronic systems.
Developer file used by Coq, an application used to develop mathematical proofs; saved in a text format and contains source code constructed in the Gallina language, which is based on an expressive formal language called Calculus of Inductive Constructions (CIC); used for storing mathematical proofs. Developers specify expressions in V files using the Gallina "vernacular," which is the syntax, or language of commands, for the Gallina language. Once V files are written, they can be compiled and run with the Coq Proof Assistant IDE, which has the program name CoqIDE.
