Solving Clock Signal Integrity And Jitter Issues


A recent blog post discussed the challenges of clock signal integrity and clock jitter in deep submicron semiconductor devices. Nice, clean clock signals are degraded due to many factors, including noise in the power delivery network (PDN). Timing variation due to clock jitter is also a serious issue, especially for chips operating at low voltage with high frequencies. The impact due to cloc... » read more

The Design Challenges Of Clock Integrity And Clock Jitter


Signal integrity is one of the many challenges faced by chip designers. Deep submicron technologies are unfriendly hosts for the nice, clean signals desired. The culprits that compromise signal integrity and introduce jitter include thermal effects, manufacturing flaws, signal crosstalk, IR (voltage) drop, signal loss over long runs, reflections, electromagnetic interference (EMI), ground bounc... » read more

STA Strategies For Fast And Efficient Signoff Performance For Multi-Billion Instance Designs


Contemporary AI, high-performance computing (HPC), mobile, and automotive designs continue to grow in size and complexity, putting a strain on the high-capacity compute required for static timing analysis (STA) workloads. Designs continue to grow at an unprecedented rate in size and complexity, outpacing the capacity of existing high-performance compute servers. A modern STA solution that can h... » read more

Meeting Today’s Challenges For LVS


At least one thing is for certain in semiconductor development: bigger and more complex designs put lots of pressure on electronic design automation (EDA) tools and methodologies. Yesterday’s chip is today’s IP block, and entire racks of electronics are being packed into system-on-chip (SoC) devices. EDA tools must evolve constantly in order to keep pace with size and complexity while meeti... » read more

Optimize Physical Verification Cost Of Ownership


As semiconductor designs continue to grow in size and complexity, they put increasing pressure on every stage of the design process. Physical verification, often on the critical path to tape-out, is especially affected. Design rule checking (DRC), layout versus schematic (LVS), and other physical verification runs take longer as chip size increases. In addition, finer geometries introduce new c... » read more

Physical Verification For Photonics Integrated Circuits


Silicon photonics is a promising solution for the explosive growth of data volume and network traffic in computing and communications. Silicon photonics integrates photonics applications on a silicon wafer, utilizing mainstream Si-based technology. Photonics integrated circuits (PIC) offer several advantages over traditional integrated circuits: faster data transfer speeds, lower power consumpt... » read more

Physical Verification In The Cloud


Cloud computing is no longer “the next big thing”; it has become a mainstream tool for business across many industries. Our own industry of IC Design and EDA, however, has been watching the cloud trend closely from the sidelines. We have been cautious and have not embraced Cloud as much as other industries – until now. What changed this year? What is driving design companies and EDA tool ... » read more
