Limits of Model Transformations for Embedded Software

Paper in proceeding, 2012

We report on an effort to use executable modeling languages for developing software for the Ericsson LTE-A uplink test bed. The test bed was a part of a 4G telecommunications system, that was presented at the Mobile World Congress in Barcelona, February 2011. The requirements for the delivered software included efficient real-time performance for signal processing on new hardware as well as a firm non-negotiable delivery deadline. Our results show that the existing model transformations were not efficient enough on the new platform and that model transformations across paradigms is a challenging task; to meet the deadline and the requirements the generated code had to be manually optimised.
