Pre-layout exploration
Compare proposed interconnect arrangements and design constraints while the architecture, stack-up and routing approach are still open.
01 / SIGNAL INTEGRITY ANALYSIS
Signal Integrity Analysis.
Design with margin.
Signal integrity simulation models your interface requirements to the behaviour of the complete interconnect. ASTRX helps engineering teams investigate loss, reflections, crosstalk and timing margin before committing to hardware—or when an existing design needs a closer look.

When an interface needs more than a routing rule
A high-speed link can be sensitive to the combined behaviour of traces, vias, connectors and the surrounding return path. A design may meet individual layout rules while still leaving uncertainty about the channel as a whole. Simulation helps turn that uncertainty into specific questions and design comparisons.
INTERFACE EXPERIENCE
Understand the channel.
Protect the margin.
Hands-on signalling and channel experience covers PCIe 3.0, 4.0 and 5.0, Ethernet platforms up to 800G, USB up to 3.2, and 56/112 Gbps serial technologies using NRZ and PAM4. Memory-interface experience includes DDR3–5 and LPDDR3–5.
This background connects pre-layout decisions to post-layout analysis and hardware verification: examining discontinuities, coupling, return paths and timing constraints, then using the findings to guide a practical design decision.
AGREE ON SCOPE / ALIGNED AROUND YOUR DESIGN
What we can investigate.
Post-layout channel analysis
Examine extracted interconnect behaviour, discontinuities, coupling and relevant timing or voltage margins against the agreed interface requirements.
Design guidance and validation
Translate findings into routing and interconnect recommendations, with a clear account of assumptions, model limitations and what needs hardware measurement.
GET STARTED
Useful inputs.
- Interface requirements and the engineering question to resolve
- Available schematics, stack-up, layout and interconnects
- Relevant device, connector and channel models, where available
- Known symptoms, measurements or constraints affecting the design
THE HANDOVER
Usable outputs.
- A defined analysis scope and documented modelling assumptions
- Channel findings and comparisons tied to the agreed requirements
- Prioritised design risks and practical improvement options
- A targeted validation plan where simulation alone is insufficient
