With the growth of SW, studies indicate a high end vehicle today is reaching 100MM lines of code and a Level 5 AV will have 400MM lines of code. With the push to develop SW functions that increase revenue and differentiation with no increase in COGS, the SW domain is critical. According to this McKenzie article, the value of SW in the vehicle is going to grow 11% per year reaching 30% of the cost of the Vehicle by 2030. Mentor has products that can help OEMs address the increasing challenge of designing and validating the application SW deployed in the vehicle.
The video demonstrates how one of Siemens EDA’s SW tools, Vista™ Virtual Prototyping in conjunction with Siemens TASS and Amesim supports OEM’s Application SW development. Vista provides SW developers a hosted run time environment eg. virtualized ECU. The demo shows SW running on the virtualized ECU very early in the process. As such developers can validate that the SW actually delivers the intended physical functions via Amesim as defined at the feature level in TASS. Again the concept is to shift validation earlier in the process by providing SW developers access to “virtualized” ECU’s.
As more and more ECU’s are built on expensive SOC architectures to meet the consolidation trend, it will be more difficult for SW developers to have access to HW for testing.
