Why Chiplet Substrate Via Density Sets the Hard Limit on Power and Signal Co-Routing
Substrate via density is the overlooked bottleneck that forces impossible trade-offs between power delivery and high-speed signal routing in chiplet packages.
P. NakamuraWhy Chiplet Disaggregation Makes Power Domain Isolation a First-Order Packaging Problem
When 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. NakamuraHow Chiplet Interconnect Protocol Overhead Eats Die Area Before Logic Synthesis Starts
Protocol 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. NakamuraHow Chiplet Reticle Size Constraints Drive Multi-Die Partitioning Before Any Logic Is Assigned
Reticle size limits at advanced nodes force chiplet partitioning decisions that lock in die count, interconnect topology, and yield math before RTL ever loads.
P. NakamuraHow Chiplet Pad-Limited Die Boundaries Force Package Substrate Routing Before Logic Partitioning Begins
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. NakamuraHow Chiplet Disaggregation Forces a Complete Rethink of Signal Integrity Budgets
Splitting SoCs into chiplets doesn't just change packaging, it fractures signal integrity budgets in ways traditional EDA flows were never designed to handle.
P. NakamuraHow Chiplet Partition Boundaries Drive PCIe Lane Allocation Before Any RTL Is Synthesized
Chiplet 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. NakamuraHow Chiplet Clock Domain Boundaries Multiply Timing Closure Complexity Across Dies
Clock domain crossings between chiplets introduce synchronization penalties that monolithic SoC timing tools were never built to handle. Here's what actually breaks.
P. NakamuraHow Chiplet Disaggregation Breaks Cache Coherency and What Architects Do About It
Splitting a monolithic SoC into chiplets fractures cache coherency in ways that traditional on-die protocols were never designed to handle.
P. NakamuraHow Chiplet Thermal Co-Design Fails When Package Engineers and RTL Teams Work in Isolation
Thermal 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. NakamuraHow Chiplet Floorplanning Constraints Cascade from Package Substrate Stackup Before Logic Synthesis Begins
Why chiplet floorplanning decisions are locked by package substrate stackup choices weeks before logic synthesis ever runs, and what that means for SoC teams.
P. NakamuraHow Hybrid Bonding Pitch Determines the Ceiling on Chiplet Integration Before EDA Tools Ever Open
Hybrid 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. NakamuraHow Thermal Resistance Kills Chiplet Density, and What Packaging Engineers Are Doing About It
Thermal resistance is the hidden tax on chiplet density. Here's how packaging engineers are fighting back with new materials and die-stacking strategies.
