Integrated Design Ecosystem™ for Chiplets and Heterogeneous Integration in Advanced Packaging Technology
Moving a design from a monolithic system-on-chip (SoC) to a chiplet architecture can multiply package design-cycle time by 10x — and quadruple the I/O pin count. A standard flip chip ball grid array (FCBGA) package for a monolithic die measures 62.5mm × 62.5mm with around 30,000 I/O pins; integrate just one ASIC and one high bandwidth memory (HBM) on a silicon or redistribution layer (RDL) interposer, and the package stays the same size while pin count climbs roughly fourfold, to about 160,000. That explosion in routing complexity is exactly the problem ASE built the Integrated Design Ecosystem™ (IDE) to solve.
Why Chiplet Packages Are So Hard to Design
Chiplets and heterogeneous integration (HI) earn their place by improving yield, enabling IP reuse, enhancing performance, and optimizing cost. But integrating them, especially for AI, demands far more connections than a monolithic SoC — and those connections must hold high density, efficient data transfer, and effective power delivery all at once. The layout density of an advanced package can run tens to hundreds of times higher than a conventional FCBGA, which breaks the traditional design flow in three ways.
First, IC chip design and package layout have historically been planned and executed separately. That separation works for a monolithic die but collapses once die-to-die interconnects dominate the design. Second, those die-to-die links are often proprietary to each customer, adding design constraints that slow the adoption of advanced packaging. Third, designing ultra-high I/O density routing on a silicon or RDL interposer requires layout design rule check (DRC) and layout versus schematic (LVS) tools that traditional package design tools often lack — which is why the design cycle can stretch to 10x that of a monolithic package.
The deeper issue is that chiplet integration cannot be optimized in isolated silos. For monolithic dies, foundries handled the silicon while package teams handled the board and substrate. Chiplet integration forces those concerns together: power, performance, and area (PPA) must be optimized at the system level, on a platform that can aggregate data from IC designers, package designers, and even board designers.
What the Integrated Design Ecosystem™ Does
ASE introduced the Integrated Design Ecosystem™ (IDE) as a collaborative design toolset built to optimize advanced package architecture across the VIPack™ platform. It manages the transition from single-die SoCs to multi-die disaggregated IP blocks — chiplets and memory — using 2.5D or advanced fan-out structures. Three capabilities define it: cross-platform interaction for layout and verification, advanced automated routing for RDL and silicon interposers with built-in DRC, and a Package Design Kit (PDK) embedded directly in the design workflow.
Interoperability is built in. The IDE supports both serial chiplet interconnect standards — extra short-reach (XSR) and SerDes — and parallel ones — Bunch of Wires (BoW), Open High Bandwidth Interconnect (OpenHBI), and Universal Chiplet Interconnect Express (UCIe). That breadth lets chiplet designers create discrete chiplets that interoperate, rather than locking each design to one proprietary link. Compared with traditional design platforms, the IDE improves design efficiency by up to 50% while enhancing design accuracy.
Inside the Workflow: From Netlist to RDL Mask
The IDE is purpose-built for chiplet integration on ASE's FOCoS (Fan-Out Chip-on-Substrate) RDL interposer or 2.5D silicon interposer. The flow begins with substrate design in a conventional package design tool to create a global file. For the interposer itself, the IDE switches to an IC design tool for automated routing, then transitions back to the package tool to optimize the RDL design and generate the Graphical Design System (GDS) file for DRC and LVS verification. Finally, an automated mask design process produces the RDL mask for fan-out or RDL wafer manufacturing.
The time savings are concrete. In a FOCoS design, completing the RDL routing from a netlist or relative coordinates traditionally takes several weeks with conventional package design tools. Using the IDE's auto router and IC design tool, ASE cuts total interposer layout design-cycle time by 50% or more. The automated mask generator is even more dramatic: it shortens RDL mask design lead time from three days to less than one hour. For a customer racing a chiplet design to market, compressing weeks of layout and days of mask preparation into a fraction of the time is the difference between hitting a product window and missing it.
From IDE to IDE 2.0: AI in the Loop
The IDE has since advanced to IDE 2.0, which embeds artificial intelligence directly in the co-design loop. Where the original IDE delivered up to 50% design-cycle reduction through EDA integration and RDL/interposer auto-routing, IDE 2.0 reduces design-analysis cycle time by more than 90% — cutting a 14-day process to roughly 30 minutes within defined design parameters — using 11 AI engines to evaluate electrical, thermal, stress, and reliability risks, and generating predictive chip-package interaction (CPI) risk assessments in under 60 seconds. It is the same trajectory, accelerated: from automating routing to automating judgment.
A Turnkey Solution for the Chiplet Era
For chiplets to be widely adopted, interoperability and plug-and-play capability are essential. The IDE provides IC and system designers a turnkey solution spanning the full process — from interposer design and stress simulation to manufacturing feasibility validation — so multiple chiplets integrate successfully into one package while system performance is optimized. As the world's largest outsourced semiconductor assembly and test (OSAT) provider, ASE pairs that design platform with the VIPack™ packaging portfolio behind it, giving customers one partner from co-design through volume production.
Conclusion
Chiplet integration trades a 10x design-cycle penalty and a fourfold pin-count increase for the yield, reuse, and performance advantages of heterogeneous integration — but only if the design tooling can keep up. ASE's Integrated Design Ecosystem™ closes that gap: up to 50% faster interposer layout, RDL mask preparation cut from three days to under an hour, and built-in DRC, LVS, and PDK support across UCIe, BoW, OpenHBI, XSR, and SerDes. With IDE 2.0 now pushing design-analysis cycles down by more than 90%, ASE gives chiplet designers the turnkey path from netlist to qualified package.

Frequently Asked Questions
Q: What is ASE's Integrated Design Ecosystem™ (IDE)? A: The Integrated Design Ecosystem™ (IDE) is ASE's collaborative design toolset for advanced packaging on the VIPack™ platform. It manages the move from single-die SoCs to multi-die chiplet and memory integration on 2.5D or advanced fan-out structures, with cross-platform layout and verification, automated RDL/interposer routing with built-in DRC, and an embedded Package Design Kit (PDK).
Q: Why does chiplet integration increase design complexity so much? A: A monolithic FCBGA package (62.5mm × 62.5mm) has around 30,000 I/O pins. Integrating one ASIC and one HBM on a silicon or RDL interposer keeps the package size but raises pin count roughly fourfold to about 160,000, and the ultra-high I/O routing needs DRC/LVS tools traditional package tools lack — pushing design-cycle time up to 10x.
Q: How much does the IDE speed up package design? A: The IDE improves design efficiency by up to 50% versus traditional platforms. In FOCoS designs it cuts total interposer layout cycle time by 50% or more, and its automated mask generator shortens RDL mask design lead time from three days to less than one hour.
Q: Which chiplet interconnect standards does the IDE support? A: The IDE supports serial standards extra short-reach (XSR) and SerDes, plus parallel standards Bunch of Wires (BoW), Open High Bandwidth Interconnect (OpenHBI), and Universal Chiplet Interconnect Express (UCIe), so chiplets from different designers can interoperate.
Q: How does IDE 2.0 differ from the original IDE? A: The original IDE delivered up to 50% design-cycle reduction. IDE 2.0 embeds AI in the co-design loop to cut design-analysis cycle time by more than 90% — a 14-day process to about 30 minutes — using 11 AI engines for electrical, thermal, stress, and reliability risk, with CPI risk assessments in under 60 seconds.
