Bringing Scalable Power Integrity Analysis To Analog IC Designs


Power integrity is a broad term in integrated circuit (IC) design and verification. However, when IC engineers are working through design signoff, power integrity analysis focuses on three specific aspects of a design: Power: Verify the chip design as implemented provides the total predicted power under different operating modes. Performance: Find and eliminate performance issues affect... » read more

Chip-Package Co-Analysis Using Ansys RedHawk-CPA


Ansys RedHawk-CPA is an integrated chip–package co-analysis solution that enables quick and accurate modeling of the package layout for inclusion in on-chip power integrity simulations using Ansys RedHawk. With RedHawk-CPA a designer can perform static IR drop analysis and AC hotspot analysis of the package layout following RedHawk static and dynamic analyses respectively. To ensure a reliab... » read more

Thermal Challenges In Advanced Packaging


CT Kao, product management director at Cadence, talks with Semiconductor Engineering about why packaging is so complicated, why power and heat vary with different use cases and over time, and why a realistic power map is essential particularly for AI chips, where some circuits are always on.   Interested in more Semiconductor Engineering videos?

Pushing Memory Harder


In an optimized system, no component is waiting for another component while there is useful work to be done. Unfortunately, this is not the case with the processor/memory interface. Put simply, memory cannot keep up. Accessing memory is slow, and it can consume a significant fraction of the power budget. And the general consensus is this problem is not going away anytime soon, despite effort... » read more

Delivering High-Speed Communications: The Back Story


Back in January, I posted a blog about what it takes to deliver high-speed communication. In that post, I talked about a new test board for our high-speed 7nm 56G PAM4 & NRZ DSP-based long-reach SerDes. We collaborated with several companies to build a high-precision board that could be used to test our SerDes in a system context. At that time, we were just finishing the opening act for thi... » read more

Engineering The Signal For GDDR6


DDR1 through DDR3 had their challenges, but speeds were below one gigabit and signal integrity (SI) challenges were more centered around static timing and running pseudo random binary sequence (PRBS) simulations. Now, with GDDR6, we are working on 16 to 20 gigabits per second (Gbps) signaling and even faster in the near future. As a result, engineering the signal for GDDR6 will require careful ... » read more

2.5D, 3D Power Integrity


Chris Ortiz, principal applications engineer at ANSYS, zeroes in on some common issues that are showing up in 2.5D and 3D packaging, which were not obvious in the initial implementations of these packaging technologies. This includes everything from how to build a power delivery network to minimize the coupling between chips to dealing with variability and power integrity and placement of diffe... » read more
