Using AI/ML To Minimize IR Drop
By Ann Mutschler - 11 Apr, 2024 - Comments: 1

IR drop is becoming a much bigger problem as technology nodes scale and more components are packed into advanced packages. This is partly a result of physics, but it's also the result of how the design flow is structured. In most cases, AI/ML can help. The underlying problem is that moving to advanced process nodes, and now 3D-ICs, is driving current densities higher, while the power envelop... » read more

A Path To Increase Cell Utilization Rate And Decrease Routing Congestion In Chip Design Floorplanning
By Jim Schultz - 30 Nov, 2023 - Comments: 0

What do chip floorplanning and city planning have in common? As it turns out, quite a lot. This was the premise for an award-winning talk given by MediaTek at this year’s Synopsys User Group (SNUG) in Taiwan. Urban city development was used as an example to understand how utilization rate (UR) and congestion relate to chip planning. UR was defined in the example as population density while... » read more

Placement And CTS Techniques For High-Performance Computing Designs
By Siemens EDA - 09 Nov, 2023 - Comments: 0

This paper discusses the challenges of designing high-performance computing (HPC) integrated circuits (ICs) to achieve maximum performance. The design process for HPC ICs has become more complex with each new process technology, requiring new architectures and transistors. We highlight how the Siemens Aprisa digital implementation solution can solve placement and clock tree challenges in HPC de... » read more

Shallow Clock Tree Pre-Estimation for Designing Clock Tree Synthesizable Verilog RTLs (Kyungpook National University)
By Technical Paper Link - 31 Oct, 2023 - Comments: 0

A technical paper titled “Shallow Clock Tree Pre-Estimation for Designing Clock Tree Synthesizable Verilog RTLs” was published by researchers at Kyungpook National University. Abstract: "Clock tree synthesis (CTS) is an important process in determining overall chip timing and power consumption. The CTS is also a time-consuming process for checking the clock tree. If the chip design and sp... » read more

A Shift Left Strategy Is One Part Of A Holistic Approach To IC Design Verification
By David Abercrombie - 28 Sep, 2023 - Comments: 0

The whole is more than the sum of its parts. –Aristotle A machine is nothing more than a collection of nuts, bolts, wheels, gears, wires, pipes, chains, and what have you. And yet, when they are all connected up properly, magic happens. Instead of a pile of parts, you have a car, or a dishwasher, or a nuclear reactor. The connections and interactions between all those parts turns the whole... » read more

What Does Shift Left With Calibre Mean For IC Designers
By Siemens EDA - 27 Sep, 2023 - Comments: 0

Driven by the world’s seemingly insatiable demand for electronics that constantly do more faster, integrated circuit (IC) design companies are continuously seeking ways to profitably deliver products with more functionality, reliability, and performance while reducing time-to-market. To accomplish this, a well-planned shift left strategy can free up critical time and resources in delivery sch... » read more

Conquer Placement And Clock Tree Challenges In HPC Designs
By Janet Attar - 11 May, 2023 - Comments: 0

High-performance computing (HPC) applications require IC designs with maximum performance. However, as process technology advances, achieving high performance has become increasingly challenging. Designers need digital implementation tools and methodologies that can solve the thorny issues in HPC designs, including placement and clock tree challenges. Placement and clock tree synthesis are c... » read more

Low-Power IC Design Without Compromise
By Janet Attar - 09 Mar, 2023 - Comments: 0

In the process of creating ICs, the digital implementation stage is focused on meeting the performance, power, and area (PPA) targets defined for the design. Traditionally, when talking about PPA metrics, “performance” has been the primary focus, with power and area recovered where possible, after meeting timing. But as designs have moved to smaller, more advanced process nodes, and as s... » read more

Considering Semiconductor Implementation Aspects Early During Network-on-Chip Development
By Frank Schirrmeister - 22 Feb, 2023 - Comments: 1

As they say, while history may not repeat itself, it sure rhymes. In 2015, I wrote the blog "Why Implementation Matters To System Design And Software." At the time, I mused that while abstraction is essential in system design, it has limitations that users must consider. Critical decisions, such as those regarding power and performance, require more accuracy than can be feasibly abstracted. ... » read more
