std 1666 system c

Abstract: SystemC® is defined in this standard. SystemC is an ANSI standard C++ class library
for system and hardware design for use by designers and architects who need to address complex
systems that are a hybrid between hardware and software

(page iv )
Introduction
As the electronics industry builds more complex systems involving large numbers of components including software, there is an increasing need for a modeling language that can manage the complexity and size of these systems.

Stakeholders in SystemC include Electronic Design Automation (EDA) companies who implement SystemC class libraries and tools, Integrated Circuit (IC) suppliers who extend those class libraries and use SystemC to model their intellectual property, and end users who use SystemC to model their systems

1.2 Purpose
1.4 Relationship with C++
This standard is closely related to the C++ programming language and adheres to the terminology used in ISO/IEC 14882:2003. This

This standard defines the public interface to the SystemC class library and the constraints on how those classes may be used.

A C++ class library may be extended using the mechanisms provided by the C++ language.

(page 20)
1.5 Guidance for readers
Clause 4, “Elaboration and simulation semantics,” defines the behavior of the SystemC kernel and is central to an understanding of SystemC.

The clauses from Clause 5 onward define the public interface to the SystemC class library.

std 1800 system verilog

Abstract: This standard provides a set of extensions to the IEEE 1364™ Verilog® hardware
description language (HDL) to aid in the creation and verification of abstract architectural level
models.

Introduction
The purpose of this standard is to provide the electronic design automation (EDA), semiconductor, and system design communities with a well-defined and official IEEE unified hardware design, specification, and verification standard language. The language is designed to coexist and enhance the hardware description languages (HDLs) presently used by designers while providing the capabilities lacking in those languages.

Introduction
The purpose of this standard is to provide the electronic design automation (EDA), semiconductor, and system design communities with a well-defined and official IEEE unified hardware design, specification, and verification standard language
(Comments: S-verilog is meant to be a complement to verilog)

SystemVerilog is a unified hardware design, specification, and verification language that is based on the Accellera SystemVerilog 3.1a extensions to the Verilog HDL [B1]a, published in 2004.


(page 5)
SystemVerilog enables the use of a unified language for abstract and detailed specification of the design, specification of assertions, coverage, and testbench verification that is based on manual or automatic methodologies

1. Overview
1.1 Scope
This standard specifies extensions for a higher level of abstraction for modeling and verification with the Verilog® hardware description language (HDL).

1.2 Purpose
SystemVerilog is built on top of IEEE Std 1364.

(page 18)
SystemVerilog adds extended and new constructs to Verilog, including the following Extensions to data types for better encapsulation and compactness of code and for tighter specification Extended operators for concise description
Extended procedural statements
Enhanced process control

Abstract: The Verilog® Hardware Description Language (HDL) is defined in this standard.

Introduction
The Verilog® Hardware Description Language (Verilog HDL) became an IEEE standard in 1995 as IEEEStd 1364-1995. It was designed to be simple, intuitive, and effective at multiple levels of abstraction in a standard textual format for a variety of design tools, including verification simulation, timing analysis, test analysis, and synthesis. It is because of these rich features that Verilog has been accepted to be the language of choice by an overwhelming number of IC designers.

Verilog contains a rich set of built-in primitives, including logic gates, user-definable primitives, switches, and wired logic.

The mixing of abstract levels is essentially provided by the semantics of two data types: nets and variables.

The Verilog language is extensible via the Programming Language Interface (PLI) and the Verilog Procedural Interface (VPI) routines

The language that influenced Verilog HDL the most was HILO-2, which was developed at Brunel University in England under a contract to produce a test generation system for the British Ministry of Defense

Achievements
Over a period of four years the 1364 Verilog Standards Group (VSG) has produced five drafts of the LRM.

Three new sections have been added. Clause 13, “Configuring the contents of a design,” deals with configuration management and has been added to facilitate both the sharing of Verilog designs between designers and/or design groups and the repeatability of the exact contents of a given simulation session.

Extreme care has been taken to enhance the VPI routines to handle all the enhancements in the Behavioral and other areas of the LRM.
