HIGH-SPEED DESIGN

Manual and automatic editing tools enable nets to be tuned precisely for track length or flight-time to achieve optimum timing characteristics

EMBRACE HIGH-SPEED DESIGN WITH CONFIDENCE

With its highest performing routing tool, eCADSTAR offers specific functionality targeted for high-speed PCB design, such as DDR2, DDR3, DDR4 and PCI Express, including min/max length, skew, delay and crosstalk limits to meet tight timing and noise margins.

MANAGING CONSTRAINTS

Maybe you want to add constraints in the schematic, where you can see what the circuit is doing. Maybe you want to do that during PCB design – selecting items to constrain in physical layout or cross-probing from schematic. Whatever you prefer, eCADSTAR works with you. Constraint Browser is built into both the eCADSTAR Schematic Editor and PCB Editor and works just one way.

LENGTH, DELAY AND SKEW (coming soon)

With standards-based buses such as DDR4 and PCI Express, there’s no leeway to scatter vias amongst buses at random positions. Length-based constraints are often the best way to route them, keeping length differences (skew) very small or zero and absolute length within tight margins.

You can set constraints in terms of delay too. This works well if application notes express constraints like that, or if the path from source to load isn’t uniform

IMPEDANCE CONTROL

Single-ended and differential impedance control is fundamental to high-speed design.

eCADSTAR automatically derives widths and spacings to meet your impedance constraints, but if you prefer, you can set those directly.

TOPOLOGY (coming soon)

Set up standard topologies like “Fly-by” quickly and easily in eCADSTAR Schematic Editor or PCB Editor. Choose from a wide selection of built-in topology templates with instant visualization.
