Overview
High-performance DFT simulation is key to completing today’s complex systems on chip (SoCs) on schedule. Because most simulators were developed before the multi-core era, they process Verilog code in a single thread, managing a single active queue of events and handling them one at a time. The serial method in

Product Lifecycle Management (PLM) for electronic systems has moved from a passive ‘fire and forget’ approach to one that is intimately involved not only during design, but also throughout the entire life of every unit delivered to the field. Siemens EDA has a white paper titled “Tessent Silicon Lifecycle Solutions” that talks… Read More
Automotive electronic content has been growing at an accelerating pace, along with a shift from infotainment toward mission critical functions such as traction control, safety systems, engine control, autonomous driving, etc. The ISO 26262 automotive electronics safety standard evolved to help ensure that these systems… Read More
Design for test (DFT) requires a lot of up-front planning that can be difficult to alter if testing needs or performance differ from initial expectations. Hierarchical methodologies help in many ways including making it easier to reduce on chip resources such as the number of test signals. Also, hierarchical test allows for speed-ups… Read More
In the early days of Atrenta I met with Ralph Marlett, a distinguished test expert with many years of experience at Zuken and Recal Redac. He talked me into believing we could do meaningful static analysis for DFT-friendliness at RTL. His work with us really opened my eyes to the challenges that test groups face in integrating their… Read More
One of the most significant and oft repeated trends in EDA is the use of information from layout to help drive other parts of the design flow. This has happened with simulation and synthesis among other things. Of course, we think of test as a physical operation, but test pattern generation and sorting have been netlist based operations.… Read More
You may have seen a recent announcement from Mentor, a Siemens business, regarding the use of their Tessent DFT software by Ambarella for automotive applications. The announcement is a good example of how Mentor works with their customers to assure design success. On the surface the announcement comes across as a nice block and… Read More
I’ve talked before about how Defacto provides a platform for scripted RTL assembly. Kind of a rethink of the IP-XACT concept but without need to get into XML (it works directly with SV), and with a more relaxed approach in which you decide what you want to automate and how you want to script it.
They’re hosting a webinar on May 28th 10-11am… Read More
There is an adage that says that quality is not something that can be slapped on at the end of the design or manufacturing process. Ensuring quality requires careful thought throughout development and production. Arguably this adage is more applicable to the topic of Design for Test (DFT) than almost any other area of IC development… Read More
Hierarchy is nearly universally used in the SoC design process to help manage complexity. Dealing with flat logical or physical designs proved unworkable decades ago. However, there were a few places in the flow where flat tools continued to be used. Mentor lead the pack in the years around 1999 in helping the industry move from … Read More
