How Many Sensors For Autonomous Driving?


With the cost of sensors ranging from $15 to $1,000, carmakers are beginning to question how many sensors are needed for vehicles to be fully autonomous at least part of the time. Those sensors are used to collect data about the surrounding environment, and they include image, lidar, radar, ultrasonic, and thermal sensors. One type of sensor is not sufficient, because each has its limitation... » read more

Blog Review: May 31


Cadence's Moshik Rubin looks at how the Portable Test and Stimulus Standard (PSS) is finding new use cases in ATE production test by enabling creation of a rich set of functional test scenarios in a reusable way. Synopsys' LJ Chen and Dana Neustadter check out the latest version of the Universal Flash Storage (UFS) standard, which doubles the data transfer rate of the preceding UFS 3.1 solut... » read more

Software-Defined Hardware Architectures


Hardware/software co-design has been a goal for several decades, but success has been limited. More recently, progress has been made in optimizing a processor as well as the addition of accelerators for a given software workload. While those two techniques can produce incredible gains, it is not enough. With increasing demands being placed on all types of processing, single-processor solutio... » read more

Week In Review: Design, Low Power


Cadence bought Pulsic, a U.K.-based developer of place-and-route tools for custom digital and analog. The acquisition follows a previous acquisition attempt by a Chinese firm in August 2022, which was blocked by the U.K. government. At the G7 Summit in Japan, IBM announced a 10-year, $100 million initiative with the University of Tokyo and the University of Chicago to develop a quantum-centr... » read more

Chiplet Planning Kicks Into High Gear


Chiplets are beginning to impact chip design, even though they are not yet mainstream and no commercial marketplace exists for this kind of hardened IP. There are ongoing discussions about silicon lifecycle management, the best way to characterize and connect these devices, and how to deal with such issues as uneven aging and thermal mismatch. In addition, a big effort is underway to improve... » read more

IP Becoming More Complex, More Costly


Success in the semiconductor intellectual property (IP) market requires more than a good bit of RTL. New advances mandate a complete design, implementation, and verification team, which limits the number of companies competing in this market. What constitutes an IP block has changed significantly since the concept was first introduced in the 1990s. What was initially just a piece of RTL (reg... » read more

The History Of CMOS


Since CMOS has been around for about 50 years, a comprehensive history would be a book. This blog focuses on what I consider the major transitions. NMOS Before CMOS, there was NMOS (also PMOS, but I have no direct experience with that). An NMOS gate consisted of a network of N-transistors between the output and Vss, and a resistor (actually a transistor with an implant) between the output and... » read more

Blog Review: May 24


Siemens' Patrick McGoff finds that designers have not had easy tools to address solderability, leaving a critical part of the manufacturing success of a PCB to the component engineer or the contract manufacturer, and points to manufacturing-driven design as a way to avoid quality issues later. Cadence's Rich Chang finds that effective UPF low-power verification and debug involves more than o... » read more

Celsius EC Solver


The Cadence Celsius EC Solver is electronics cooling simulation software for accurate and fast analysis of the thermal performance of electronic systems. It enables electronic system designers to accurately address the most challenging thermal/electronics cooling issues today. The Celsius EC Solver utilizes a powerful computational engine and meshing technology that enables designers to model a... » read more

Chips Getting More Secure, But Not Quickly Enough


Experts at the Table: Semiconductor Engineering sat down to talk about the impact of heterogeneous integration, more advanced RISC-V designs, and a growing awareness of security threats, with Mike Borza, Synopsys scientist; John Hallman, product manager for trust and security at Siemens EDA; Pete Hardee, group director for product management at Cadence; Paul Karazuba, vice president of marketin... » read more
