Configuration Files

Concept

Configuration files are files that store persistent settings and parameters used to customize the behavior of software systems or hardware tools. In software engineering, they can be automatically identified by their persistence across application executions and slower change rate compared to other state files. In hardware verification tools such as MicroTESK, lightweight configuration files complement architecture description languages by specifying subsystems (e.g., MMU, caches, TLBs) that are difficult to express in general-purpose ADLs.

Overview

A configuration file is a file used to store settings, parameters, or structural descriptions that customize or control the behavior of a software system, tool, or hardware component. Configuration files typically persist across executions and change less frequently than other application state, which distinguishes them from transient or runtime data files.
