Blog Review: July 21


Cadence's Paul McLellan listens in as Partha Ranganathan of Google argues that a new era of Moore's Law is emerging, defined both by the efficient design of hardware accelerators and improving the ways that hardware is utilized. Siemens EDA's Chris Spear continues exploring classes in SystemVerilog with a look at the relationship between the class variables that point to an object and how to... » read more

Design For Test Data


As design pushes deeper into data-driven architectures, so does test. Geir Eide, director for product management of DFT and Tessent Silicon Lifecycle Solutions at Siemens Digital Industries Software, talks with Semiconductor Engineering about a subtle but significant shift for designing testability into chips so that test data can be used at multiple stages during a device’s lifetime. » read more

Blog Review: July 14


Siemens EDA's Wei-Lii Tan considers the tradeoffs when running library characterization in the cloud and how to think about running CPUs in parallel, the cost of throughput, and runtime reductions. A Synopsys writer checks out the reduced blanking feature in HDMI 2.1, which can help reduce the transmission rate while keeping the resolution and refresh rate intact for higher resolution displa... » read more

CEO Outlook: Chiplets, Longer IC Lifetimes, More End Markets


Experts at the Table: Semiconductor Engineering sat down to discuss chiplets, longer IC lifetimes, and a spike in the number of end applications with Lip-Bu Tan, CEO of Cadence; Simon Segars, CEO of Arm; Joseph Sawicki, executive vice president of Siemens IC EDA; John Kibarian, CEO of PDF Solutions; Prakash Narain, president and CEO of Real Intent; Dean Drako, president and CEO of IC Manage; an... » read more

Streaming Scan Network


The traditional approach to moving scan test data from chip-level pins to core-level scan channels is under pressure due to the dramatic rise in design size, design complexity, and test adaptation. In the traditional approach to delivering scan test data to cores, each core requires a dedicated connection to chip-level pins, which doesn’t allow for much flexibility, as the dependencies betwee... » read more

ASIC/IC Verification Trends With A Focus On Factors Of Silicon Success


At long last we come to the final installment of our four-part series presenting the findings of the Wilson Research Group Functional Verification 2020 study. In this article we discuss verification trends in IC/ASIC language and library adoption, low power management, and verification effectiveness. We then take a deeper dive into two somewhat surprising phenomena revealed in the data: the ... » read more

Reducing Power Delivery Overhead


The power delivery network (PDN) is a necessary overhead that typically remains in the background — until it fails. For chip design teams, the big question is how close to the edge are they willing to push it? Or put differently, is the gain worth the pain? This question is being scrutinized in very small geometry designs, where margins can make a significant difference in device performan... » read more

Retimers Replacing Redrivers As Signal Speeds Increase


Retimers are undergoing a renaissance as new PHY protocols prove too demanding for redrivers. Redrivers and retimers both have been used to extend wired signal reach over the years. But redrivers have dominated this space due to their relative simplicity and lower cost. That balance is beginning to change. “A retimer represents three things no one wants in their system — area, cost, a... » read more

Bringing Reset And Power Domains Together


The Unified Power format (UPF) standard enables designers to add power intent for a design. For power management, designers typically partition a design into power domains. Interactions between these power domains are done through various power control logic, like retention logic, isolation logic, and level shifters. Designers need to validate that the power control logic does not introduce new... » read more

Blog Review: July 7


Cadence's Sangeeta Soni provides a primer on the PIPE SerDes architecture and some of the changes that can introduce verification challenges for SerDes compliant PHY and MAC devices. Siemens EDA's Chris Spear demystifies the $cast() method in SystemVerilog, which checks values at runtime rather than compile time, and gives some examples of when it is useful. Synopsys' Chris Clark warns th... » read more
