VPI

Vpi is a term that may refer to multiple unrelated topics, depending on context. It does not denote a single, universal entity, and its meaning is typically clarified by surrounding text or branding.

In computing and electronics, VPI most often refers to the Verilog Procedural Interface. This is a standard that allows external programs written in languages such as C or C++ to interact with and control a Verilog simulation. The VPI provides a set of routines and interfaces that enable tasks, functions, and data access within a simulated design, supporting advanced verification, test benches, and integration with external software tools.

The name VPI is also used by a U.S.-based company that designs and manufactures high-end analog audio equipment, particularly turntables. In this context, VPI serves as a brand name rather than an acronym, and the term is associated with a line of audio products rather than a technical specification.

Beyond these examples, Vpi may appear as an acronym or identifier for various organizations, programs, or products in different fields. Because the meaning can vary widely, readers should consult the accompanying definitions or disambiguation notes to determine which Vpi is being referenced.
