Teams. How the work splits.

  • 01

    Architecture

    Workload analysis, microarchitecture, and the PPA tradeoffs behind every block.

  • 02

    RTL Design

    SystemVerilog implementation of the compute datapath, memory hierarchy, and interfaces.

  • 03

    Design Verification

    Testbenches, coverage closure, and formal proofs against the specification.

  • 04

    Physical Design

    Synthesis through place-and-route, with timing, DRC, and LVS signoff.

Partners & platforms. Standing on tall shoulders.
