Case Study: NSITEXE cuts processor development time by 50% to deliver five RISC‑V custom processors for autonomous driving SoC with Synopsys ASIP Designer

NSITEXE Develops Multiple RISC-V Based Custom Processors for Autonomous Driving SoC with Synopsys’ ASIP Designer

NSITEXE, a semiconductor IP provider for automotive and industrial automation, needed to develop a virtual prototype of its multicore Data Flow Processor (DFP) for autonomous driving and connected-car applications. The project required five application-specific processors (RISC-V controllers with dedicated vector engines) but faced a tight schedule and limited resources, making in-house development from scratch impractical.

Using Synopsys’ ASIP Designer and its RISC-V example models as a starting point, NSITEXE customized vector extensions, automatically generated an SDK and cycle‑accurate instruction-set simulators, and integrated the processors into a SystemC virtual prototype for system-level verification and early software bring-up. The approach let a two‑engineer team deliver all five custom processors on schedule, meet performance and functionality goals, and cut development time and resource needs by 50%.
