Marvell’s Custom Compute (Trainium 3, Inferentia 3 successor candidates), Optical Interconnect (post-Celestial AI $5.5B), and Networking SoC roadmap all transition to glass substrates by 2027. ChipletOS ships the cross-EDA workflow stack today.
AWS Trainium 2 ramped on TSMC SoIC + organic substrate. Trainium 3 candidates target glass interposer for HBM4-stacked AI training. ChipletOS HBM4 cal head closes 90.3% of BEM-vs-Palace gap on 4507 corner cases (v2 retrain) — 6/6 regimes calibrated, avg 74% gap closure.
Marvell’s photonic switch roadmap competes directly with Nvidia post-Celestial. Glass substrate is the integration substrate of choice for high-density optical I/O. ChipletOS PROV 4 photonics + glass-TGV impedance models are the workflow lock.
ChipletOS golden_mmwave_77ghz kit (40.52 Ω at 77 GHz, BEM multi-solver-verified) covers the band-optimized package routing your 224G+ interconnect needs. First-in-industry buyer spec table.

| CC-BY OSS slice | glass_tgv_diffpair (universal scaling law) + 1M-row CC-BY corpus | 5 public glasses, 110 MB |
Up to $5.5B PRE-REVENUE. Defensive vs Nvidia photonic switch. Sets the modern precedent for “Marvell pays defensively for substrate-layer IP that locks competitors out.”
$700M, ~10× rev. Workflow lock-in premium. Same pattern: Genesis owns the cross-EDA workflow lock; substrate-layer IP that compounds.
~$200M, materials data moat alone — no solver. Genesis’s 1M-row CC-BY corpus + closed 6.75M-row strict-grouped corpus is Granta-class.
$107.5M, ~3.5× rev, niche photonics-FDTD. Closest analog. Genesis is at least as moated.
