Speeding Up 3D Design
By Brian Bailey - 14 Nov, 2019 - Comments: 0

2.5D and 3D designs have garnered a lot of attention recently, but when should these solutions be considered and what are the dangers associated with them? Each new packaging option trades off one set of constraints and problems for a different set, and in some cases the gains may not be worth it. For other applications, they have no choice. The tooling in place today makes it possible to de... » read more

Analyzing Testbench Design Performance Using Verdi Performance Analyzer
By Synopsys - 09 Oct, 2019 - Comments: 0

Performance continues to be key factor for the design of any complex system-on-chip (SoC). Moreover, complexity is increasing every day, which poses a challenge for engineers to track performance of the design, yet they are tasked to continuously increase chip performance. This paper describes the challenge to measure design performance and explains how Verdi Performance Analyzer enables run ti... » read more

3D Power Delivery
By Brian Bailey - 12 Sep, 2019 - Comments: 1

Getting power into and around a chip is becoming a lot more difficult due to increasing power density, but 2.5D and 3D integration are pushing those problems to whole new levels. The problems may even be worse with new packaging approaches, such as chiplets, because they constrain how problems can be analyzed and solved. Add to that list issues around new fabrication technologies and an emph... » read more

Lithography Challenges For Fan-out
By Mark LaPedus - 12 Feb, 2019 - Comments: 3

Higher density fan-out packages are moving toward more complex structures with finer routing layers, all of which requires more capable lithography equipment and other tools. The latest high-density fan-out packages are migrating toward the 1µm line/space barrier and beyond, which is considered a milestone in the industry. At these critical dimensions (CDs), fan-outs will provide better per... » read more
