Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

Introduction
Precision and high-performance electrical products can be defined as products that integrate
mechanical, electrical/electronic, and software technologies. These digitally integrated products are
expected to simultaneously achieve high functionality and low cost. In order to meet these needs,
computer technology, which enables designing of highly functional products in a limited period of time,
is necessary. Effective measures to realise such design can include active use of computer simulations
from the functional design stage upstream of a design process, evaluating aspects of the feasibility of
the expected function, and narrowing the appropriate design solutions at an early stage.
This document examines the business requirements for using simulation in the functional design
process and identifies the key technical capabilities needed to satisfy those requirements. Based on a
comparison with the capabilities of current technologies validated through research and experimental
examples, this document identifies a number of digital validation technologies which need to be
developed in order to meet future business needs, and the associated standardization requirements.
