IEEE 1364

Description / Abstract: Verilog is a hardware description language (HDL) that was standardized as IEEE Std 1364™-1995 and first revised as IEEE Std 1364-2001. This revision corrects and clarifies features ambiguously described in the 1995 and 2001 editions. It also resolves incompatibilities and inconsistencies of IEEE 1364-2001 with IEEE Std 1800™-2005.

The intent of this standard is to serve as a complete specification of the Verilog HDL. This standard contains the following:

 — The formal syntax and semantics of all Verilog HDL constructs

 — The formal syntax and semantics of standard delay format (SDF) constructs

 — Simulation system tasks and functions, such as text output display commands

 — Compiler directives, such as text substitution macros and simulation time scaling

 — The programming language interface (PLI) binding mechanism

 — The formal syntax and semantics of the Verilog procedural interface (VPI)

 — Informative usage examples

 — Informative delay model for SDF

 — The VPI header file
