An automotive zone controller ASIC program was undertaken to support next‑generation vehicle architectures requiring high reliability, functional safety, and low‑ latency data communication. The objective was to consolidate multiple vehicle functions into zonal architecture while meeting stringent automotive safety standards and performance requirements.
The design integrated complex analog and digital subsystems across different technology nodes, with compliance to ISO 26262 functional safety standards up to ASIL‑D. The program required end‑to‑end system definition, ‑safety compliant design implementation, and seamless integration of multi‑channel power control with high‑performance digital processing. Managing mixed ‑signal complexity, safety certification, and aggressive development timelines were key challenges addressed through a tightly coordinated execution approach.
Key Highlights
- Multi‑channel analog power supply switch/control with 33 channels and programmable I²t rating
- Dual core processor‑based digital ASIC with time‑synchronized Ethernet
- Low latency data switching to and from vehicle ECUs
- Rich IP portfolio including RISC‑V, SRAM, QSPI, DMA, ADC, Flash controller, and safety manager
- Complete RTL‑to‑GDSII flow for both analog and digital ASICs
- ISO 26262 compliance for ASIL‑B and ASIL‑D components
- Full integration of analog and digital blocks into a unified ‑top level layout
