Synopsys Advances 3D PCIe 6.0 Connectivity

Synopsys demonstrated PCIe 6.0 operating at 64 GT/s within a stacked, face-to-face chip architecture. The design delivered bandwidth reaching 128 GB/s through an eight-lane configuration using PAM4 signaling. Therefore, the test moved PCIe connectivity beyond conventional two-dimensional chip layouts.

The company used a 5-nanometer PCIe 6.0 PHY adapted for three-dimensional integrated circuit technology. Synopsys built the test chip from an existing PCIe 6.0 implementation and added changes for stacked dies. Silicon testing confirmed that the technology operated successfully after packaging, startup, and measurement.

The demonstration also showed receiver performance exceeding PCIe 6.0 bit-error requirements by wide margins. Meanwhile, the architecture shortened connections between separate dies compared with traditional side-by-side packaging. This structure can support higher bandwidth, reduced latency, improved signal integrity, and greater computing density.

3D Packaging Targets AI and Data Center Systems

Modern AI processors increasingly combine specialized functions across several dies instead of relying on one large chip. As a result, chip designers need faster links between computing, memory, networking, and storage components. Synopsys positioned its latest demonstration as one option for meeting those growing connectivity demands.

The technology can support AI accelerators, high-performance processors, SmartNICs, DPUs, storage controllers, and data center switches. It can also support systems using Compute Express Link connectivity for memory and accelerator expansion. Synopsys is extending existing interface technology toward more complex multi-die platforms.

Three-dimensional packaging creates technical challenges because engineers must manage electrical behavior across stacked components. Synopsys addressed TSV placement, die interaction, inductors, signal performance, and full-stack modeling during development. The company also worked to limit unnecessary TSV additions while maintaining PCIe 6.0 performance.

Synopsys Builds on Long PCIe Development History

Synopsys has developed PCIe technologies for more than two decades across several generations of the standard. Its portfolio includes PHY technology, digital controllers, security components, verification systems, and interoperability testing tools. The company has supported about 4,000 customer tape-outs across seven PCI Express generations.

The latest project links that established PCIe portfolio with the semiconductor industry’s shift toward multi-die architectures. Synopsys combines electronic design software with interface technologies for advanced packaging and heterogeneous integration. These tools support architecture planning, package optimization, software development, system validation, and manufacturing analysis.

The milestone also strengthens Synopsys’ position within the expanding market for advanced semiconductor packaging. AI and HPC systems continue requiring greater bandwidth while power and physical space remain major design constraints. Synopsys now offers a validated PCIe 6.0 path designed specifically for emerging three-dimensional chip architectures.
