Getting Rid Of Heat In Chips
By Brian Bailey - 20 Jul, 2023 - Comments: 1

Power consumed by semiconductors creates heat, which must be removed from the device, but how to do this efficiently is a growing challenge. Heat is the waste product of semiconductors. It is produced when power is dissipated in devices and along wires. Power is consumed when devices switch, meaning that it is dependent upon activity, and that power is constantly being wasted by imperfect de... » read more

Blog Review: July 19
By Jesse Allen - 19 Jul, 2023 - Comments: 0

Siemens' Keith Felton argues that co-design-driven semiconductor package planning and prototyping is critical for design success and points to how interchange formats enable designers to make trade-off decisions for both the package and the board and communicate those recommendations back to the other design team in formats that are native to their tools. Cadence's Xin Mu explains precoding ... » read more

Spectre-BHB: Speculative Target Reuse Attacks Version 1.7
By Arm - 19 Jul, 2023 - Comments: 0

In March 2022, researchers within the Systems and Network Security Group at Vrije Universiteit Amsterdam disclosed a new cache speculation vulnerability known as Branch History Injection (BHI) or Spectre-BHB. Spectre-BHB is similar to Spectre v2, except that malicious code uses the shared branch history (stored in the CPU Branch History Buffer, or BHB) to influence mispredicted branches within ... » read more

DAC/Semicon West Wednesday
By The SE Staff - 13 Jul, 2023 - Comments: 1

Trade restrictions against China were a regular topic of discussion at both DAC and Semicon West this week. Five Chinese startups exhibited prominently at this week's Design Automation Conference, in the wake of increasingly restrictive trade regulations that limit the sale of U.S. and European EDA tools used to develop advanced semiconductors. Most attendees interviewed said privately th... » read more

Solving The Last-Mile Delivery Problem
By John Koon - 06 Jul, 2023 - Comments: 0

Retailers are deploying robots to cut costs and improve efficiency, opening new opportunities for chipmakers as well as a host of new challenges. Key to this strategy are autonomous roadside delivery robots (ARDRs). Retailers have been facing razor-thin profit margins for years and have turned their sights to increasing operational efficiency to stay competitive. Solving the last-mile delive... » read more

Curbing Automotive Cybersecurity Attacks
By John Koon - 06 Jul, 2023 - Comments: 1

The relentless cyberattacks on the automotive sector are not limited to vehicles and have an impact on the entire automotive supply chain, so the pressure is on the automotive ecosystem to understand the necessary standards and regulations for vehicles and components. While the process of attaining compliance adds additional effort, in the long run, the increase in cybersecurity will save the a... » read more

Innovative NoC Implementation Dramatically Speeds Derivative Design
By Arteris - 05 Jul, 2023 - Comments: 0

The Inuitive team faced a significant challenge when developing a derivative design based on the NU4000, their first vision-on-chip processor. The NU4000 employs the Advanced eXtensible Interface (AXI) on-chip communication bus protocol developed by Arm. However, removing one of the NU4000’s three vector cores resulted in access to only a limited number of AXI ports. The problem was that ... » read more

Semiconductor Engineering sat down to talk about more openness in EDA data, how increased complexity is affecting time to working silicon, and the impact of geopolitics, with Joseph Sawicki, executive vice president for IC EDA at Siemens Digital Industries Software; John Kibarian, president and CEO of PDF Solutions; John Lee, general manager and vice president of Ansys' Semiconductor Business U... » read more

Blog Review: June 28
By Jesse Allen - 28 Jun, 2023 - Comments: 0

In a podcast, Siemens' Spencer Acain discusses the role of AI and machine learning in IC verification and how it could help address noise by analyzing different signals from the diagnosis data to figure out the real root cause of a failure. Synopsys' Ian Land and Ron DiGiuseppe find that designers of aerospace microelectronics are applying lessons and technologies learned from the automotive... » read more
