Software instrumentation based tracing for the verification of timing of embedded systems is becoming more and more important. This applies to single-core projects but even more to the increasingly common multi-core projects. Just as the need for visualization increases, hardware tracing solutions run into bandwidth limitations.

The way in which software instrumentation is implemented depends on the operating system in use. So far, there is no standard. The OSEK/AUTOSAR task hook routines are, for various reasons, unable to support effective tracing.

With OStimHooks we have created a standard, which defines a unified interface between the operating system and timing measurement and tracing tools. At the core is a highly efficient measurement or tracing technology and also simple implementation.

OStimHooks has been presented to the AUTOSAR timing group. The goal is to implement the standard with partners, to develop it further and, if appropriate, to make part of the AUTOSAR standard.

Until now there was no standard for exchange of timing information between tools. OT1 is GLIWA's offering, which is gradually being adopted by timing tool suppliers, research groups and research projects.

OT1 has been presented to the AUTOSAR timing group. The goal is to implement the standard with partners, to develop it further and, if appropriate, to make part of the AUTOSAR standard.

Read more at the dedicated OT1 website. There you will find the standard available as a free download.

clang-format configuration file for GLIWA C code

When integrating T1 into an embedded software project, GLIWA provides template C source modules. These provide the required interfaces and tell the user in comments what needs to be done. These templates are formatted using clang-format for which the configuration file can be found here for download. Using this clang-format configuration file for the GLIWA templates instead of any other clang-format configuration files avoids massive changes to the templates when editing them. This simplifies browsing the differences.

GLIWA Statement with regard to Log4j Security Flaw
T1 does not use Log4j, hence it is not affected by the recently discovered Log4j security flaw.

GLIWA goes YouTube
Our brand new videos provide concrete and entertaining insights into the functions and advantages of the various components of the T1 Analysis Suite.

GLIWA embedded systems has a new legal form

After a form-changing transformation completed on 1st July 2021 the full new company name is now:

GLIWA embedded systems
GmbH & Co. KG

We kindly ask you to include this name in your systems and to use it in your future correspondence and documents. The address of our head office, the VAT-ID and the D.U.N.S. remain unchanged.
