Meet your electrical performance criteria by setting design constraints. Apply constraints to parts, pins, electrical nets (E-nets), differential pairs and other objects in the Constraint Browser.
Setting constraints means you can verify that your design meets standards—internal or external. And your design follows those constraints as you go, because it costs much less to avoid an issue than to find and fix it later.
A constraint set early works for you, but consistency is critical. A constraint in library design rules must look the same and work the same as one applied locally, in schematic or PCB.
Set or edit constraints in Schematic Editor or PCB Editor. Define technology and design rules in Library Editor. Keep your design settings in sync with your master library or make them local.
Local settings can be useful for prototyping, while synchronized settings are best for production.
Manage constraints in Constraint Browser, in a clearly presented object hierarchy. Look and feel is the same whether you do that in Schematic Editor or PCB Editor.
Forward and back annotation ensure that your constraints are always in sync. Define classes and groups to organize your design and constraints. Create differential pairs and buses. Cross probe selections between the canvas and Constraint Browser in both Schematic Editor and PCB Editor. Highlight objects you constrain by setting colors and taking advantage of visibility options such as shading between differential +/- and E-net pin pairs.
Route with confidence, assisted by simultaneous display of real-time measurements versus constraints.
With eCADSTAR you can:
Perform what-if analysis to optimize high-speed performance, to solve and verify critical PCB design requirements.
Testing and identifying the sources of signal integrity issues in a device, then fixing them, is a big challenge.
AMI analysis goes beyond traditional waveform simulation.
A flexible, modular approach allows you to build an eCADSTAR bundle to fit your pcb design requirements.
