When chiplet I/O pad rings hit their physical limits, package substrate routing decisions lock in before logic partitioning even starts. Here's why that order matters.
P. NakamuraWhen multiple chiplets share one HBM stack, bandwidth allocation decisions made at the package level can silently starve entire compute dies.
P. NakamuraSplitting SoCs into chiplets doesn't just change packaging, it fractures signal integrity budgets in ways traditional EDA flows were never designed to handle.
P. NakamuraChiplet partition decisions made before RTL synthesis directly determine PCIe lane counts, die-to-die bandwidth, and substrate routing long before any logic is written.
P. NakamuraClock domain crossings between chiplets introduce synchronization penalties that monolithic SoC timing tools were never built to handle. Here's what actually breaks.
P. NakamuraChiplet disaggregation creates multi-vendor procurement complexity that traditional semiconductor sourcing models were never designed to handle.
P. NakamuraSplitting a monolithic SoC into chiplets fractures cache coherency in ways that traditional on-die protocols were never designed to handle.
P. NakamuraThermal co-design in chiplet packages breaks down when RTL teams and packaging engineers operate in silos, here's what that costs and how to fix it.
P. NakamuraWhy chiplet floorplanning decisions are locked by package substrate stackup choices weeks before logic synthesis ever runs, and what that means for SoC teams.
P. NakamuraThe vertical order of dies in a 3D-IC stack silently dictates power delivery efficiency, thermal headroom, and PDN impedance long before any logic is placed.
P. NakamuraHybrid bonding pitch sets hard limits on chiplet integration density that no EDA tool or floorplan trick can overcome. Here's what the numbers actually mean.

P. NakamuraWafer-level fan-out RDL pitch and layer count quietly set the hard limits on chiplet I/O density before substrate or die design even enters the picture.
P. NakamuraRedistribution layer fanout pitch quietly caps chiplet integration density before interconnect standards or die size ever become the limiting factor.
P. NakamuraBump pitch between chiplets and organic substrates is quietly constraining signal density, power delivery, and yield in advanced packaging, here's what the numbers actually mean.
P. NakamuraRandom die placement on advanced packages destroys yield in ways traditional models never predicted. Here's what the math actually looks like.
P. NakamuraDisaggregating SoCs into chiplets doesn't just split silicon, it splits trust. Here's why securing die-to-die interfaces is genuinely unsolved.
P. NakamuraKnown-good-die testing is the unglamorous bottleneck throttling chiplet yield and cost. Here's how the industry is solving it, and where it's still stuck.
P. NakamuraCo-packaged optics and silicon photonics are rewriting the rules for chiplet interconnect bandwidth, here's what that means for next-gen heterogeneous designs.
P. NakamuraWafer-to-wafer bonding offers unmatched interconnect density, but yield math punishes it harshly. Here's why that tradeoff is shifting.
P. NakamuraEmbedded bridge dies are turning passive silicon interposers into active routing layers, here's what that means for chiplet bandwidth and cost.
P. NakamuraDie-to-die latency isn't just a spec footnote, it's quietly determining which functions can be disaggregated into chiplets and which cannot.
P. NakamuraThermal resistance is the hidden tax on chiplet density. Here's how packaging engineers are fighting back with new materials and die-stacking strategies.
