Develop and integrate UPF/CPF-based power intent across subsystem and SoC hierarchies.
Collaborate with architects to define power management strategies that meet performance, power, and area targets.
Design and integrate clocking infrastructure, including clock generation, clock distribution, clock gating, clock muxing, reset architectures, and clock monitoring mechanisms.
Drive RTL design and integration of power management controllers, clock controllers, reset controllers, and related infrastructure IPs.
Prepare and hold architecture, design, and verification reviews with technical staff throughout project lifecycle
Analyze and debug low-power and clocking issues identified during simulation, emulation, synthesis, and silicon bring-up.
Architect and integrate SoC interconnects and bus fabrics, including AXI, AHB, APB, and other on-chip communication protocols.
Lead small teams of design engineers to architect, design and verify digital subsystems.
Drive subsystem and SoC integration activities, ensuring seamless connectivity between processors, memories, peripherals, accelerators, and third-party IPs.
Drive RTL development and integration of infrastructure IPs, including clock controllers, reset controllers, power management controllers, DMA engines, and bus fabric components.
Analyze and debug integration, clocking, power, CDC/RDC, and protocol-related issues throughout the development cycle.
Validation/bring-up of designs on silicon, providing support to cross-functional teams
