Choosing Between Static and Dynamic Shapes


That title might be a touch misleading. We’re not here to talk about why to convert shapes between static and dynamic. Rather, I want to talk about why you should NOT be doing this. Every design has some conductor shapes in it (or at least a very large percentage of them). What style to use is a choice that will impact performance through your entire flow; let the shape’s purpose guide you.... » read more

Don’t Get Stranded On Islands, Delete Them


No, this isn’t a Hollywood movie. We’re talking about pieces of plane shapes with no connections to them, not an idyllic private oasis in the Caribbean (sorry). Removing shape islands is something you’ve always been able to do in the Allegro layout environments, but the flow for achieving this has improved significantly in recent years. Come with us, and we’ll compare what the flow u... » read more

Raising The IQ Of Your MEMS-Based IC Design Flow


By Nicolas Williams and Qi Jing Internet of Things (IoT) applications depend on smart objects that interact with the real world. So your IoT project is likely to contain ICs that integrate micro electro-mechanical systems (MEMS), such as accelerometers, pressure sensors, motors, and microphones that acquire data for analysis. These projects are finding their way into automobiles, phones, and... » read more
