Sometimes a standard is a victim of its own success, at least for a while as the economics catch up to the technology. When a standard like USB 3.0 is announced, with a substantial performance increase over USB 2.0, some of the use cases come on board right away. Others, where vendors enjoy a decent ROI with good-enough performance,… Read More

SEMulator3D: GlobalFoundries Process Variation Reduction
At SEMICON last month, Rohit Pal of GlobalFoundries gave a presentation on their methodology for reducing process variation. It was titled Cpk Based Variation Reduction: 14nm FinFET Technology.
Capability indices such as Cpk is a commonly used technique to assess the variation maturity of a technology. It looks at a given parameter’s… Read More
Another debug view in the UVM Toolbox
One of the biggest endearing qualities of a debug environment for any type of coding is availability of multiple ways to accomplish a task. Whether the preference is keyboard shortcuts, mouse left-click drill-down and right-click pull-down menus, source code view, hierarchical class view, or graphical relationship view, … Read More
How to Reduce Maximum Power at RTL Stage?
Of course that reduction has to stay throughout the design cycle up to layout implementation and fabrication. Since the advent of high density, mega functionality SoC designs at advanced nodes and battery life critical devices played by our fingertips, the gap between SoC power requirement and actual SoC power has only increased.… Read More
Cadence Completes Power Signoff Solution with Voltus-Fi
You probably remember Cadence introduced Voltus towards the end of last year at their signoff summit. This was aimed at digital designers. Prior to that they had announced Tempus, their static timing analysis tool. More recently they announced Quantus QRC extraction. All of these tools that end in -us have been re-architected… Read More
A Deeper Insight into Quantus QRC Extraction Solution
Last month Cadenceannounced its fastest parasitic extraction tool (minimum 5 times better performance compared to other available tools) which can handle growing design sizes with interconnect explosion, number of parasitics and complexities at advanced process nodes including FinFETs, without impacting accuracy of … Read More
Transaction-based Emulation
Verification has been going through a lot of changes in the last couple of years. Three technologies that used to be largely contained in their own silos have come together: simulation, emulation and virtual-platforms.
Until recently, the workhorse verification tool was simulation. Emulation had its place but limits on capacity… Read More
Analog Model Equivalence Checking Accelerates SoC Verification
In the race to reduce verification time for ever growing sizes of SoCs, various techniques are being adopted at different levels in the design chain, functional verification being of utmost priority. In an analog-digital mixed design, which is the case with most of the SoCs, the Spice simulation of analog components is the limiting… Read More
Speeding up IP and Data Management
IP and Data Management (DM) for SoC teams has gradually moved from ad-hoc approaches using simple Excel spreadsheets, to home-grown software that is specific to a project or company, and finally to commercially supported tools. One such commercial toolset for IP lifecycle management is from Methodics, named ProjectIC –… Read More
Layout-aware Diagnosis
Traditional test methodologies have been based on the functional model, that is to say the netlist. The most well-known is probably the stuck-at model which grades a sequence of test vectors by whether they would have managed to notice the difference between a fully functional design and one where one of the signals was permanently… Read More
