Intecs - Fail-Safe Railway Signaling Software

Since 1997 Intecs has developed fail-safe software for railway signaling applications conforming to the applicable standards (CENELEC EN 50128). Some examples of its signaling safety software and services are:

• Design, development, and test of the core software used on a standard platform based on the Motorola MC68xxx processor and utilized for realizing onboard and ground-based signaling apparatus
• Design, development and testing of the Euroradio stack; the Euroradio communication stack enables communication between onboard and ground devices within the European rail traffic management system (ERTMS) structured according to the ISO/OSI standard
• Design, development and testing of the application software and man-machine interface (MMI) subsystem specification that is mounted on-board rolling stock

Support tools for bit sequence telegrams

Intecs is involved in the development of a number of support tools for the design and generation of the telegrams of bit sequences utilized by railway signaling equipment (SCMT, SSC and ERTMS).

Railway signaling systems simulators

Intecs designs and develops simulators for railway signaling systems for test and system integration activities. The languages most commonly used are ANSI C, C++, Assembler, ADA 83 and ADA 95.

Software reverse engineering

Railway systems developed for use in safety-related applications must demonstrate that the development process followed conforms to the applicable standards (i.e. CENELEC).

For this purpose it is often necessary to carry out reverse engineering activities in order to reconstruct, from the written code, the document required by CENELEC standards (e.g. architectural design, detailed design, software requirements, etc.) Intecs possesses the tools and capabilities for carrying out such activities.

Currently Intecs operates on the ANSI C, C++ and assembler languages and uses suitable software tools for management of requirements for the compilation of architectures documents. Unless otherwise specified by the client, the V-lifecycle is adopted.

The documents produced are strictly conformant to the CENELEC standards relative to the applicable safety integrity level (SIL).

About Intecs

Intecs is an Italian private company with offices in Rome, Naples, Pisa, Milan, Turin and Toulouse (France). About 30% of its turnover share is in the railway market. More than 90% of its employees (about 400 people) have a university degree in computer science, engineering or other scientific disciplines.

In December 1994 Intecs passed the formal certification audit for ISO 9001 and in 2003 for Vision 2000. This places Intecs among the first companies thus certified in Italy. The certification applies for any software development project in the civilian, space, and defense domains. Intecs is a CMM level 3 company and the CMMI level 3 certification is in progress.
