Open V File
V extension files have various uses, which we are going to describe below.
Verilog
A file with a V extension, when used by the Verilog Hardware Description Language, is a source code file.
It specifies a model of an electronic system and is compatible with both Verilog 2005, as well as previous Verilog standards, such as Verilog-95 or Verilog 2001.
Due to the change from the Verilog 2005 standard to SystemVerilog, which adds new design modeling functions, SystemVerilog source files have an SV file extension.
Verilog files are written in plain text and can be created and edited by any common text editor.
Raw image
The raw images, in this case, are saved in a file with extension V, created by ppmtoyuvsplit, which is a Unix-based program designed to divide portable PixMap images (.PPM files) into Y components, U and V and these in turn are saved in separate files.
The V file stores the 'V' chrominance component, or color, for the image.
These files can later be restored back to the original PPM file using the rollback utility yuvsplittoppm.
Coq Source Code
In this case, the V files are used to store mathematical tests, being in a text format and containing the source code built in the Coq Language, based on Construction Inductive Calculus (CIC).
To open a V file, you need to have one of the following programs installed, prior to knowing what type of file you have
