other development tools and platforms, and application lifecycle management. SCADE has been predominantly used in aerospace, according to Sovani, but it's just as applicable to automotive, especially now that SCADE is compliant with ISO-26262 ("Road vehicles – Functional safety"). This compliance, says Sovani, "means that embedded code rendered by SCADE is automatically prequalified to ISO-26262, and therefore, does not have to go through as much rigorous testing. Development testing is reduced." Also new in SCADE is a module for testing human-ma- chine interfaces (HMI). SCADE Display, continues Sovani, "reduces the effort required for testing HMI applications by enabling model testing to be performed earlier in the development cycle, thus saving expensive design reworks, and automating test execution and results analysis." A NEW WAVE IN RADAR "Radars are typically delivered by radar suppliers," says Sovani, but for vehicles, the integration is still up to the automakers. Integration goes beyond just slapping in a finished module and wiring it to the in-vehicle electronics. Continues Sovani, "Radar behaves differently in free space than when it's installed on the fascia of a vehicle. It's also important to figure how radar will perform in various traffic and environmental conditions." Sovani says that automotive radar is both a geometrically complex and electromagnetically large problem. Through its acquisition of Delcross Technologies last year, Ansys is able to simulate radar performance using a hybrid approach between the finite element method (FEM; full-wave) and the shooting and bouncing ray analysis (SBR; asymp- totic) method. FEM looks at the data elements in the tens of wavelengths, such as that from potentially interfering on-board electronics and mobile devices in the passenger cabin. When the radar is installed in the fascia of a car, FEM and SBR together help in analyzing the geometrically large problem that covers hundreds of wavelengths. Last, SBR helps in understanding radar performance when a vehicle is moving through traffic, passing other vehicles, trees and buildings— geometrically huge environments with thousands of wavelengths. Obviously, vehicles are not standing still. Neither is the engi- neering software to analyze those vehicles. walter-tools.com/us Fully integrated efficiency Faster, more efficient, more cost-effective.
