IEEE 1364-1995

IEEE 1364-1995 is a standard hardware description language based on the Verilog(R) Hardware Description Language, intended to support clear specification of digital behavior and structure. It is relevant to engineers working with components, circuits, devices, and systems where formal description, simulation, and design communication are important. As a superseded English-language standard, IEEE 1364-1995 remains useful as a reference point for legacy designs and documentation that depend on the original language definition.

Overview of IEEE 1364-1995

This standard defines an early IEEE hardware description language model rooted in Verilog terminology and practice. IEEE 1364-1995 provides a common basis for describing digital logic at different levels of abstraction, helping engineers document how circuits should behave and interconnect. In product and engineering workflows, it serves as a technical reference for language syntax, semantics, and design intent, especially where older HDL-based assets must be understood, reviewed, or maintained accurately.

Typical use cases

IEEE 1364-1995 is typically used for digital system modeling, logic design documentation, and simulation-oriented work involving electronic components and circuit-level behavior. It may support development of control logic, interface modules, and subsystem descriptions in engineering environments that rely on HDL-based specifications. The standard is also relevant when maintaining archived Verilog code, checking legacy design assumptions, or aligning technical documentation with the original IEEE 1364-1995 language rules.

Why it matters

For teams handling hardware design and verification, this standard helps reduce ambiguity in how a digital system is described and interpreted. Consistent language definitions support better design control, easier review, and more reliable testing across projects and suppliers. Because IEEE 1364-1995 is superseded, it can be especially important for compliance checks, legacy procurement, and risk reduction when an existing design or archive must be matched to its original specification without introducing unintended changes.
