Dear Bruce, I have some questions regarding traceability according to ISO26262/ASPICE: In Harmony aMBSE, during use case analysis, there are two steps where we add trace links. At first we stucture requirements, when we add trace links from requirements to use cases. Next it comes to modelling and we finally create state machines. There we add trace links to states, transitions, etc. Please can you summarize the important issues in both steps? I cannot remember seeing an example (Deskbook, book) for a traced state machine. Thank you very much! Best regards Matthias

Hi Bruce, please can you provide the models of roadrunner Intersection Controller described in "Real-time UML Workshop for Embedded Systems", too? Thank you! Best regards Matthias

Hi Bruce! I was enjoying reading your "Doing hard time" it covers a lot a basics and it is fun to revisit it from time to time. I was wondering can I get it as an ebook somewhere? Thx! Denny
