Carving Up Verification


Anirudh Devgan, executive vice president and general manager of [getentity id="22032" e_name="Cadence's"] System & Verification Group, sat down with Semiconductor Engineering to discuss the evolution of verification. What follows are excerpts of that conversation. SE: What’s changing in [getkc id="10" kc_name="verification"]? Devgan: Parallelism, greater capacity and multiple engine... » read more

Dealing With Unintended Behavior


Functional verification was already tough enough, but having to identify behaviors that were never defined or intended opens up the search space beyond what existing tools are capable of handling. However, while you may not be able to eliminate unintended behaviors, a design team is not helpless. There are several steps that can be taken to reduce the likelihood of these problems getting int... » read more

IP Qualification During RTL Synthesis


By Sudhakar Jilla and Arvind Narayanan The use of IP (intellectual property) as basic building blocks is an established practice for SoC designs. Most IP is developed without chip-level context and very little knowledge about physical design, which can introduce unwanted schedule risk into the design process. Much of the risk of IP development can be mitigated by using new physical synthesis... » read more

IP Qualification with Oasys-RTL


With increasing design sizes and complexities, the use of IP (intellectual property) as basic building blocks for better SoC design is also increasing. This paper presents the challenges faced during IP integration at the SoC level and what can be done to mitigate those risks during IP development. Mentor’s Oasys-RTL RTL floorplanning and physical synthesis tool offers a unique IP qualificati... » read more

Uncovering Unintended Behavior


Very few companies ever had to worry about security until recently. Over the past couple of years, we have seen increasing evidence that our connected systems are vulnerable. The recent distributed denial of service (DDoS) attack, which made many Internet sites unavailable, has focused attention on Internet of Things (IoT) devices such as digital video recorders and cameras that have Internet a... » read more

IoT Security Ratings Needed


Concerns about security have been growing alongside adoption of the IoT, and it seems to be making some headway. This is good news, if it continues, because one of the biggest concerns about buying connected devices is that they can provide inroads into personal data. Data security has been a persistent annoyance for several years. Almost anyone who travels or shops at major department store... » read more

2017: Tool And Methodology Shifts


As the markets for semiconductor products evolve, so do the tools that enable automation, optimization and verification. While tools rarely go away, they do bend like plants toward light. Today, it is no longer the mobile phone industry that is defining the direction, but automotive and the Internet of Things (IoT). Both of these markets have very different requirements and each creates their o... » read more

Power Management Vs. State Machines


In the last several years, contemporary SoCs (systems-on-a-chip) have become very complex silicon solutions. They now consist of hundreds of millions of gates, 100 or more discrete Semiconductor Intellectual Property (SIP) blocks, high-speed data channels, megabytes of volatile and non-volatile embedded memory, increasing amounts of analog/mixed signal functionality, multiple CPU cores and mult... » read more

Border Tax Shakeup


A border tax is the talk of the financial world. While this has clear implications for car manufacturers, where it's rather easy to tell where parts such an engine block or a braking system were manufactured, it's far less tangible when it comes to electronics in general, and semiconductors in particular. In a complex SoC, IP can be developed in more than one country, and multinational techn... » read more

The Challenges Of Designing 28G And 56G SerDes IP


The industry move to 56 Gbps PAM4 is undoubtedly one of the greatest challenges currently facing SerDes IP designers and their customers. To begin with, shifting to 56 Gbps PAM4 immediately causes a loss of 9 dB. While the baud rate is 28 Gbaud, there are now three eyes stacked on top of each other. Nevertheless, there is still demand for 35+ dB reach. This is a significant challenge which requ... » read more
