What is an SVH file?

An SVH file is a source code file written in the SystemVerilog language, which is a superset of the Verilog language used for specifying models of electronic systems. It is similar to an .SV file but contains constants that are included with other SystemVerilog files.

Since SVH files are saved in plain text, you can edit them in any text editor. However, you may want to use an editor designed specifically for handling SystemVerilog source code, such as Sigasi Studio or ModelSim.

SystemVerilog is used in the semiconductor and electronic design industry. It is a combination of hardware description language (HDL) features and hardware verification language (HVL) features with C and C++ features. It was adopted as IEEE Standard 1800-2005 in 2005, with the IEEE Standard 1800-2009 released in 2009 and IEEE 1800-2017 released in 2017.

NOTE: IEEE stands for Institute of Electrical and Electronics Engineers.
