Chiplet redundancy strategies force die area tradeoffs that ripple through packaging decisions long before yield models or logic partitioning begin.
P. NakamuraSubstrate via density is the overlooked bottleneck that forces impossible trade-offs between power delivery and high-speed signal routing in chiplet packages.
P. NakamuraWhen chiplets from different process nodes share a package, power domain isolation stops being a design afterthought and becomes a packaging problem that must be solved before floorplanning begins.
P. NakamuraProtocol overhead in chiplet interconnects consumes meaningful die area before logic synthesis begins, and most teams discover this far too late in the design flow.
P. NakamuraReticle size limits at advanced nodes force chiplet partitioning decisions that lock in die count, interconnect topology, and yield math before RTL ever loads.
P. NakamuraWhen 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. 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. 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. 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. NakamuraThermal resistance is the hidden tax on chiplet density. Here's how packaging engineers are fighting back with new materials and die-stacking strategies.
P. NakamuraHow chiplet designs force radical changes in power delivery networks, from voltage domains to decap placement strategies.
