Intelligence as in the term artificial intelligence (AI) involves learning or training, depending on which perspective it is viewed from –and it has many nuances. As the basis of most deep learning methods, neural network based learning algorithms have gained usage traction, when it was shown that training with deep neural network… Read More
Designing a fully digitally controlled DC-DC buck converter
One of the unsung heroes of our digital world is the modest voltage converter. Batteries and wired power sources rarely match up with the supply needs for advanced ICs. Leading edge ICs have multiple voltage domains and very often, as in the case of processors, use dynamic voltage scaling to help conserve power. Looking at where … Read More
Tackling Manufacturing Errors Early with CMP Simulation
CMP (Chemical Mechanical Planarization or also known as Chemical Mechanical Polishing) is a wafer fabrication step applied generally after a chemical deposition –intended to smoothen and to flatten (planarize) wafer surfaces with the combination of chemical and mechanical forces. Developed at IBM and since its introduction… Read More
Emulation Evaluation for the Ages!
One of the more entertaining things I get to observe in the semiconductor ecosystem is competitive customer evaluations of tools and IP. Seriously, this is where the rubber meets the road no matter what the press releases say.
This time it was emulators which is one of the most interesting EDA market segments since there is no dominant… Read More
Sequential Equivalency Checks in HLS
Higher level synthesis (HLS) of an IP block involves taking its high-level design specification –usually captured in SystemC or C++, synthesizes and generates its RTL equivalent. HLS provides a faster convergence path to design code stability, promotes design reuse and lowers front-end design inception cost.
HLS and Mentor… Read More
Improving Library Characterization with Machine Learning!
For SOC designers that are waiting for library models the saying “give me liberty or give me death” is especially apropos. Without libraries to support the timing flow, SOC design progress can grind to a halt. As is often the case, more than just a few PVT corners are needed. Years ago, corners were what the term sounded like – the 4 corners… Read More
Catapult Design Checker Finds Coding Errors Before High Level Synthesis
In a recent whitepaper Gagandeep Singh, Director of Engineering at Mentor, a Siemens Business outlines a flow using Catapult Design Checker that helps in early detection of coding errors as many companies are turning to High-Level Synthesis (HLS) methodology. This requires that high -level C++ models are correct, that ambiguities… Read More
Eliminate PCB Re Spins using an Integrated Multi Dimensional Verification Platform
The rapidly increasing complexity of today’s designs, combined with schedule pressure to deliver innovative products to market as quickly as possible, strains engineering resources to the limit, often to the point of breaking. As a result, 17% of all projects get canceled, and another 28% miss their target release date (Source:… Read More
Mentor’s Symphony in Tune with AMS Designer Needs
Mixed signal simulation is a very hot topic these days. In modern designs, it is harder to draw a line between the analog and digital and work with them independently. Analog blocks are showing up everywhere. Even in what would have qualified as a digital design a few years ago, now designers need to look at things like PLLs, IOs and … Read More
Mentor’s Busy ITC and Major Test Product Updates
In conjunction with the 2018 International Test Conference, Mentor has several interesting test announcements. They also have a busy round of technical activities, including a number of technical papers, presentations, tutorials and a poster from a major customer about using Mentor. I’d like to touch on the two product related… Read More
