The Evolution Of Digital Twins


Digital twins are starting to make inroads earlier in the chip design flow, allowing design teams to develop more effective models. But they also are adding new challenges in maintaining those models throughout a chip's lifecycle. Until a couple of years ago, few people in the semiconductor industry had even heard the term "digital twin." Then, suddenly, it was everywhere, causing confusion ... » read more

Pivoting Toward Safety-Critical Verification In Cars


The inclusion of AI chips in automotive and increasingly in avionics has put a spotlight on advanced-node designs that can meet all of the ASIL-D requirements for temperature and stress. How should designers approach this task, particularly when these devices need to last longer than the applications? Semiconductor Engineering sat down to discuss these issues with Kurt Shuler, vice president of... » read more

Universal Verification Methodology Running Out Of Steam


For the past decade or so, the Universal Verification Methodology (UVM) has been the de facto verification methodology supported by the entire EDA industry. But as chips become more heterogeneous, more complex, and significantly larger, UVM is running out of steam. Consensus is building that some fundamental changes are required, moving tools up a level of abstraction and making them more ag... » read more

Open-Source Verification


Ask different people what open-source verification means and you will get a host of different answers. They range from the verification of open-source hardware, to providing an open-source verification infrastructure, to providing open-source stream generators or reference models, to open-source simulators and formal verification engines. Verification is about reducing risk. "Verification is... » read more

Linting RISC-V Designs


As the open-source RISC-V instruction set architecture (ISA) continues to gain momentum, the growing number of RISC-V design solutions and their flexibility creates a problem when choosing the most reliable and robust solution from a number of contenders. Sure, a RISC-V IP design must be compliant to basic ISA standards and should contain a testing suite demonstrating that compliance. But sh... » read more

Formal Verification Of Floating-Point Hardware With Assertion-Based VIP


Hardware for integer or fixed-point arithmetic is relatively simple to design, at least at the register-transfer level. If the range of values and precision that can be represented with these formats is not sufficient for the target application, floating-point hardware might be required. Unfortunately, floating-point units are complex to design, and notoriously challenging to verify. Since the ... » read more

Methodology Vs. Problem-Solving


When I was 18, I bought a Vespa ’67: the famous Italian scooter. It was already very old then, totally beaten-up, but luckily I had a friend who owned an auto-repair shop, and he was kind enough to give me some access at night. For several weeks, I taught myself the art of metal bodywork, ending up with a beautiful metallic sky-blue ‘67 Vespa. God, I loved that machine! Then one day, ... » read more

Vtech: Bus Performance, FPGA Debug


It has been a long time since I was able to talk about a new verification company, but today I can introduce you to Verification Technology, or Vtech for short. If you do a search for them, you will probably find a company that sells baby monitors and kids toys. This is not that company. So, let's make sure you have the right web address to start with https://vtech-usa.com/ or https://vtech-inc... » read more

Machine Learning Enabled Root Cause Analysis For Low Power Verification


By Himanshu Bhatt and Susantha Wijesekara Next-generation SoCs with advanced graphics, computing and artificial intelligence capabilities are posing unforeseen challenges in verification. Designers and verification engineers using static verification technologies for low power often see many violations in the initial stages. Efficient debugging and determining root cause is a real issue and ... » read more
