Part 2 – Confidence in the use of software tools Get the Most out of Development and Testing with the Maker of the Blue Box V11.01

Confidence in the use of software tools ISO 26262-8-11• Minimize the risk of systematic faults in the developed product due to malfunctions of the software tool (introduce or fail to detect errors) ― Evaluation of a software tool by analysis: Level of Confidence • Tool Impact (TI): TI1, TI2 (general estimation) • Is there a possibility that a malfunction of a tool introduces or fails to detect an error TI1 = no, TI2 = all other cases • Tool error Detection (TD): TD1, TD2, TD3 ― TD1, high degree of confidence in measures that a malfunction will be prevented or detected• Methods for Qualification ― TCL3, TCL2 ― TCL = Tool Confidence Level Get the Most out of Development and Testing with the Maker of the Blue Box V11.01

Confidence in the use of software tools ISO 26262-8-11 TCL3 *** TCL2 *** * iSYSTEM Regression Test Tool Suite may increase confidence from use ** iSYSTEM Tools are not developed according to a safety standard today Get the Most out of Development and Testing with the Maker of the Blue Box V11.01

Company Management System• 25+ years R&D and production of embedded systems development & test tools• ISO 9001:2008 ― Well documented company management system ― iSYSTEM has been certified in the field of the following activities: Design, development, production and sales of embedded microcontroller development and test tools, managing custom projects and providing professional services related to such tools• Yearly audits of our processes from a certification authority• Audits can also be performed by you. You are welcome to visit our R&D and production division Get the Most out of Development and Testing with the Maker of the Blue Box V11.01

Safety Manual• Description of features/functions (to be used in a safety project or to be qualified)• Explanation how these features/functions should (not) be used• Manuals: ― User Manual, Hardware Reference Manual, Getting Started Guides, PCB Desing Guidelines, ...• System Requirements in general or specific to a micro controller• Description of well-known workarounds dedicated to a specific micro controller• … Get the Most out of Development and Testing with the Maker of the Blue Box V11.01

Tool Pre-Qualification Environment• If a specific function of an iSYSTEM tool has to get verified in the customer’s use case context• Consists of reference hardware plus test cases to verify several functions of an on-chip debug and trace tool such as: ― Standard debugging and IDE functions, e.g. memory read, write, step, memory dump, download, flash programming, etc. ― Advanced debugging with trace and profiling (especially time measurements) ― Software test with code coverage and unit test ―…• Is an extract of iSYSTEM’s internally used regression test tool suite• May be ported/adapted to a customer’s target system Get the Most out of Development and Testing with the Maker of the Blue Box V11.01

Summary – Measures to show proof that iSYSTEM tools fit in the context of a safety project• From the very beginning of this standardization process we pursue the wording on tool qualification. To implement the requirements at customer side specified in the standard, we derived organizational measures and documentation as well as a tool setup for the verification of dedicated tool functionality• External and internal audits of iSYSTEM’s development and test process take place on a regular basis ― An iSYSTEM customer is welcome do visit our R&D and production division• Documentation – Safety Manual• Tool Pre-Qualification Environment Get the Most out of Development and Testing with the Maker of the Blue Box V11.01
