Perforce at Embedded World 2024: Making software development more secure and sustainable
DevOps specialist also presents comprehensive support for latest MISRA standard
D
evOps specialist Perforce will be demonstrating the steps that the diverse embedded community can take to get closer to developing embedded, responsible, sustainable systems on stand 4-510 in Nuremberg from April 9 to 11.
Perforce will also be demonstrating how its solutions support the latest MISRA C++ coding standard, MISRA C++:2023, published in November 2023, which integrates the AUTOSAR C++14 guidelines and supports more recent versions of C++. As founding members of the MISRA working groups, Perforce experts have leveraged 25 years of experience to provide the best coverage for the new guidelines.
With the rapid growth of electric and
autonomous vehicle segments and the increasingly central role of embedded software in the automotive industry, Perforce will also be presenting highlights from its annual State of Automotive Software Development Report. The report discussions will include year-over-year survey results comparisons, the importance of standards and compliance, and notable emerging trends for automotive development.
Products featured on the stand will include the static analysis range, such as Klocwork and Helix QAC, Helix Core for version control, Hansoft project management, Helix ALM for application lifecycle management, and Methodics IPLM, IP lifecycle management for semiconductor chip design.
Conference presentations: In addition, Perforce will be presenting on two topics delving deeper into MISRA and Automotive Software:
Static Sentiment Analysis: Intelligently Finding Hotspots in Intent – by Alex Celeste, Principal Software Engineer at Perforce Software, on April 10 from 1.45-3.30pm local time
2024 State of Automotive Software Development – by Jill Britton, Director of Compliance at Perforce Software and Steve Howard, Product Evangelist, Static Analysis at Perforce Software on April 11 from 9:30-10am local time.
2G Switch-off and Legacy Device Migration
Some 2G networks have already been withdrawn, and in Europe a large proportion of the remainder are due to be switched off before the end of 2025 explains Tim Taberner, technical sales director Advantech IIOT
A
s cellular technology advances towards mass 5G adoption, service providers are constantly looking for ways to optimise the use of the radio spectrum available to them. One recent victim of this progression will be the provision of 2G and 3G services, which are now seen as out of date, hold little commercial value, and are therefore being withdrawn. Indeed, in the case of 3G networks, this has already happened in many countries even though, confusingly, the earlier generation 2G services will remain available for a short while longer.
The reason for this apparent contradiction is due to the operational characteristics of the two generations from the perspective of
data transmission. 3G systems marked the first generation where, from a user perspective, the interface was effectively the same as for any other IP based network, albeit slower and somewhat unreliable. Because of this, when 3G services have been withdrawn, all that has been necessary to migrate to LTE or 5G has been to replace the modems or routers with new generation equivalents, with the change being transparent to any connected equipment, other than seeing an increase in performance and reliability.
This is not the case for 2G networks, where the way connections are established and data is transferred is different, and migration to later generations of cellular

network is therefore more complex. Due to this incompatibility, 2G networks have been kept running beyond the end date of 3G systems because the service providers are aware that, in the SCADA, automation, and M2M workspace, many systems still rely on this technology, especially in the energy and utility industries. Connected legacy devices are deployed which have many years of useful service life remaining, but which cannot directly access the IP based communications mandated by more modern communication networks. However, time is running out rapidly for these services. Some 2G networks have already been withdrawn, and in Europe a large proportion of the remainder are due to be
