System, PCB, & Package Design : Teardrops and Tapers – Improving Manufacturability and Yield Automatically

Tyler

Teardrops (also called fillets) are the blending area of a cline entry into a pad, while tapers are the gradual transition from one line-width to another along a path. These two core concepts appear in nearly any PCB or IC package substrate today. They act to smoothen the intersection of the two objects, eliminating acute angle acid traps while also contributing to better signal integrity along the path.

However, any…

Whiteboard Wednesdays: Whiteboard Wednesdays - Solving Scan Compression Congestion Issues with Modus 2D Elastic

References4U

In this week's Whiteboard Wednesdays video, Rohit Kapur, Distinguished Engineer at Cadence Design Systems, discusses the topic of scan compression and the layout problems created as compression ratios grow. The Modus DFT Software Solution targets this impact using its patented physically aware 2D Elastic Compression architecture, without any impact on fault coverage or chip size. For more information, read the datasheet…

定制IC芯片设计 : Virtuosity: 着色数据是否与MPT流程兼容？

KomalJohar

毋庸置疑，兼容的设计能提高公司的业绩和生产效率。任何不兼容的设计都会增加产品的设计周期。为了便于高阶工艺节点设计中，工程师能创建与多重图形技术（MPT）相兼容的设计流程，我们在多重图形工具栏上，引入了兼容检查功能（Compliance Checker）的选项。在设计过程中, 您肯定遇到过这样的情况，版图设计的图形有颜色信息，但是根据MPT 流程设置，这些图形却不需要着色，通过兼容检查功能，便能把它们标记出来，这个功能还能标出有颜色偏移的图形实例，这些图形实例根据MPT 流程本不应该发生颜色...

XTeam

Another successful DVCon U.S. 2019 has come and gone, but this year had a particularly interesting highlight. With nearly 900 attendees, a bigger program of tutorials, panels, papers, and posters, and a sold-out expo, the Best Paper award was even more prestigious than ever before. This year, the award was renamed to the Stuart Sutherland Best Paper Presentation. Stu was a leading Verliog and SystemVerilog expert, and…

Analog/Custom Design: Virtuosity: Reading Vector Files in Virtuoso Visualization and Analysis

Arja H

Prior to IC6.1.8 and ICADVM18.1, to view digital and analog waveforms along with the applied stimuli, it was necessary to run the simulations using both digital and analog solvers. This could be a time-consuming process. However, now you can read in the digital stimuli files directly into Cadence Virtuoso Visualization and Analysis, the ADE waveform window. In addition, you can plot the analog waveforms using the stimuli…

Analog/Custom Design: Virtuosity: Identifying Those Traces

AdityaMainkar

With the ever-increasing number of simulations required to be run these days, the sheer number of plots can be overwhelming and it can be difficult to figure out which Cadence Virtuoso ADE XL, Virtuoso ADE Assembler or Virtuoso ADE Explorer history, test or corner each plot belongs to. To help with this, from IC.6.1.8/ICADVM18.1 Virtuoso Visualization and Analysis we have made identifying and comparing traces across…

Analog/Custom Design: Spectre Tech Tips: Device Aging? Yes, even Silicon wears out

Moustafa Moham

While most of us would like our electronic gadgets to last forever, the reality is that these gadgets have a lifetime. Most of the time, the lifetime of devices is limited by either mechanical (switch, relay), or thermal (fuse, capacitor) failures. However, as microchips designed in advanced technologies become more pervasive, the lifetime of microchips has become an additional issue.

Several effects contribute to device…

Analog/Custom Design: Virtuosity: New Flexible Subwindows

Arja H

Plots in Cadence Virtuoso Visualization and Analysis can be plotted in a window or subwindow. Subwindows allow you to see plots from different analyses side by side. Until IC6.1.8/ICADVM18.1, the subwindows were not very flexible. Now, we've improved these so that you can choose any grid layout of subwindows up to a 6x8 grid. In addition, you can resize the subwindows easily and move them around. These subwindow configurations…
