Simulations include effects of layout parasitics, complex modulated signals, and digital control circuitry. With PathWave RFIC Design, you can simulate in both the frequency and time domain and bring your designs to and from Cadence Virtuoso. Accurately model components on silicon chips. Optimize designs with sweeps and load-pull analysis. Integrate RF designs in the Cadence Virtuoso environment. Increase performance using Monte Carlo and yield analysis. Simplify debugging with safe operating area warnings. Utilize the latest foundry technology immediately. -

Ansys Pharos
Ansys
Pharos combines Ansys' unparalleled EM engine capacity with a proprietary high-capacity circuit simulation engine to perform coupling analysis and provide ranking of potential EM crosstalk aggressors per victim node. By highlighting the most susceptible nets, designers can focus their design decisions to manage EM crosstalk on these nets and de-risk the design process. Pharos combines unparalleled extraction engine capacity with a built-in simulation engine to perform EM analysis and provide ranking of potential EM crosstalk aggressors per victim net. This allows designers to focus on the most critical nets in the design. Increasing design complexity, along with the broad scope of magnetic field interference, makes identifying all EM crosstalk susceptible victim/aggressor net pairs a very challenging, if not impossible, task. -

Review Board
Beanbag
Code review doesn't have to be so hard. Review Board takes the pain out of code review, saving you time, money, and sanity so you can focus on making great software. You can review just about anything. Code, documents, artwork, you name it! There's more to your project than just code. Documentation, artwork, website designs, interface mockups, release announcements, feature specifications, and the list goes on. A picture paints a thousand words, and can be key in a review. Drag-and-drop one or more images onto your review request to make them instantly reviewable. Your team will be able to click-and-drag anywhere on the image and leave a comment. When they do, you'll see their comment right along with that portion of the image. Made a tweak to the image? Just upload a new revision and view a visual diff of the changes through one of our many image diff modes. Sometimes you'll have other text content that's not part of your source tree. -
