Analysis Of Multi-Chiplet Package Designs And Requirements For Production Test Simplification

By Vineet Pancholi - 21 Nov, 2024 - Comments: 0

In recent years there has been a sharp rise of multi-die system designs. Numerous publications targeting a large variety of applications exist in the public domain. One presentation [2] on the IEEE’s website does a good job of detailing the anecdotal path of multi-die systems by way of chiplet building blocks integrated within a single package [2]. The presentation includes references to a ha... » read more

A new technical paper titled "Rethinking Programmed I/O for Fast Devices, Cheap Cores, and Coherent Interconnects" was published by researchers at ETH Zurich. Abstract: "Conventional wisdom holds that an efficient interface between an OS running on a CPU and a high-bandwidth I/O device should be based on Direct Memory Access (DMA), descriptor rings, and interrupts: DMA offloads transfers fr... » read more

Enabling Innovative Multi-Vendor Chiplet-Based Designs

By Elad Alon - 26 Sep, 2024 - Comments: 0

Chiplets have emerged as a critical implementation paradigm for semiconductor products, primarily because they can deliver cost benefits relative to a non-chiplet-based approach. The first, most well-proven, and obvious benefit of a chiplet-based approach is manufacturing cost. Manufacturing cost benefits are accrued either from the appropriate selection of chiplet die size, or by optimizin... » read more

Managing Performance in Modern SoC Designs

By John Min - 26 Sep, 2024 - Comments: 0

As industries like automotive, consumer electronics, telecommunications and artificial intelligence (AI) push for greater processing power, efficiency and scalability, system-on-chip (SoC) designs have rapidly evolved to meet these demands. With the growing complexity of modern SoCs, designers face the challenge of managing an increasing number of interconnected IP blocks while ensuring seamles... » read more

Simultaneous Bi-Directional Signaling: A Breakthrough Alternative For Multi-Die Assemblies

By Ramin Farjadrad - 29 Aug, 2024 - Comments: 0

In designing multi-die systems-in-package, with or without chiplets, it is easy to think of the interconnect between dies as simply analogous to the interconnect between functional blocks on a single die. But this analogy can lead architects and designers into a blind alley from which it becomes impossible to meet system performance and power requirements. The reason lies in fundamental differe... » read more

Here At Last! Automated Verification Of Heterogeneous 2D/3D Package Connectivity

By Michael Walsh - 25 Jul, 2024 - Comments: 0

By Michael Walsh and Jin Hou with Todd Burkholder The heterogeneous integration of multiple ICs in a single package along with high-performance, high-bandwidth memory is critical for many high-performance computing applications. After everything has been heterogeneously integrated and packaged, such designs feature complex connectivity with many hundreds of thousands of connections, making i... » read more

Optimizing Interconnect Topologies For Automotive ADAS Applications

By Ashley Stevens - 25 Jul, 2024 - Comments: 0

Designing automotive Advanced Driver Assistance Systems (ADAS) applications can be incredibly complex. State-of-the-art ADAS and autonomous driving systems use ‘sensor fusion’ to combine inputs from multiple sources, typically cameras and optionally radar and lidar units to go beyond passive and active safety to automate driving. Vision processing systems combine specialized AI accelerators... » read more
