Is Your Board High-Speed?
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.
What is the Difference Between eCADSTAR ADVANCED HS and BASE?
eCADSTAR ADVANCED HS adds the ability to control high-speed routing topology and interactive tools to make routing easier, including:
- Impedance-controlled single-ended and differential routing – essential for clean signaling
- Length, delay, and skew-based routing to meet timing constraints
- Single-ended and differential routing topology control so you can meet bus layout standards
- Assisted single-ended and differential routing with automatic end-routing for fast, accurate results
- A SPICE Controller for verifying your analog circuits that ensures your design data remains in sync with what you analyze
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:
- Pre-layout SI analysis so engineers can analyze and simulate proposed high-speed topologies in their schematic design, or even conceptually
- Physical design SI analysis, extracting high-speed equivalent circuits from the physical layout so you can experiment, analyze, and optimize
- IBIS-AMI modeling, for ultra-fast buses that include signal-conditioning hardware, like PCIe Gen.3
- Power Integrity and EMI analysis to validate on-PCB power distribution, optimize decoupling and identify electromagnetic radiation issues that can break international standards
- eCADSTAR ADVANCED HS gives you the features and options you need to design high-speed circuits correctly
Design your way
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.
Logical, physical, and electrical visibility
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.
