Even if most of your PCB is, say, analog, or a low-speed digital circuit, high-speed circuits are often present, and they require topology control. Modern PCBs are rarely entirely “low-speed” or “high-speed”.
High-speed IO is standard for many common devices. DDR4 memory is layout-critical, even if it runs relatively slowly. The same goes for common buses like PCI Express or USB Type-C. Even DC-to-DC step-down (buck) converters are high-speed and layout-critical, because, unlike older linear converters, parts of their circuit run at high frequencies.
eCADSTAR ADVANCED HS adds the ability to control high-speed routing topology and interactive tools to make routing easier, including:
More optional extras are available with eCADSTAR ADVANCED HS. You can add Autorouting or Gerber Import as with BASE, but you can also choose from a range of advanced and fully built-in features to help you optimize high-speed performance. Here they are:
What you need to control high-speed topologies like fly-by for DDR4 memory, or interfaces like USB Type-C and PCI Express.
Design variation management to control your products for different markets and customers.
All these views are essential when you design high-speed circuits, so in eCADSTAR you always have full control and visibility.
For example, relative skew constraints have been set between these differential byte lane strobes and clock, and they are both configured for controlled topology and impedance.
View and adjust settings any time you like and check results instantly to tune your PCB for maximum performance.
