Job Description

NoC Design Lead (×2 openings) Location: Bangalore, India | Company: LTSCT — L&T; Semiconductor Technologies Limited Reporting To: Chandra — Senior Architect, DC HW Systems | Experience: 10+ years (mandatory) Role Summary We are hiring two NoC Design Leads to own the stacked Network-on-Chip that forms the data backbone of xPU — 4 physical planes delivering 12 TB/s cross-section bandwidth. You will architect and implement coherency, routing, QoS, and bandwidth allocation across the BFOS arrays, banked SRAM, HBM controllers, UCIe links, and the host interface. This role is central to sustaining the extreme bandwidth and latency targets the compute architecture demands. Key Responsibilities





• Architect and implement the 4-plane stacked NoC delivering 12 TB/s cross-section bandwidth across all on-chip and off-chip endpoints.
• Define topology, routing algorithms, virtual channels, and arbitration to guarantee deadlock-free, high-throughput data movement.
• Design QoS and bandwidth-allocation mechanisms balancing traffic between dual BFOS arrays, 512 SRAM banks, HBM controllers, UCIe, and host.
• Own the on-chip coherency protocol and its interaction with SRAM, HBM, and the host-interface coherency layer.
• Drive micro-architecture, RTL, and integration of routers, network interfaces, buffers, and clock-domain crossings.
• Model and analyze latency, bandwidth, and congestion via cycle-accurate simulation and traffic generators; close performance targets.
• Collaborate with PD on floorplan-aware NoC partitioning across the 4 physical planes and with DFT/verification on coverage.
• Define QoR/performance metrics, mentor engineers, and represent NoC in architecture and integration reviews. Required Skills & Experience
