Signal Integrity Analysis, (H-SPICE, IBIS, Ansoft HFSS)
As signal speeds increase, the quality and integrity of the PCB layout becomes increasingly critical for optimizing the performance of the system. Simulation and analysis can help to avoid the painful hours of debug in a lab to find the source of bit errors, when you determine you have a noise problem. At the same time, SI simulation can prove to be time consuming and expensive.
With our extensive experience in SI, we will work with you at the beginning of the design to mutually determine the practical level of simulation required for your specific board, to mitigate the risk. We find in most cases, appropriate SI CAD guidelines, combined with simulation of just a few critical interfaces, is the optimal approach. Then we support the layout process real-time to solve any routability vs. performance issues before they have a chance to affect schedule and cost.
Power Integrity Analysis
DO YOU HAVE:
- Multiple Voltage rails or fragmented power planes?
- Lower voltages and tolerances?
- Increased current requirements?
- Tighter noise budget?
If so, you probably need to perform a Power Integrity (PI) analyses on your design to guarantee proper function of your board? DWB is your partner for Power Integrity analysis services. We provide PI DC analysis (voltage drop and current density) and PI AC analysis (decoupling and plane noise). Contact us for your Power Integrity analysis needs. We can supply you with a free quote and a sample PI analysis report to demonstrate our Power Integrity analyzes capabilities.
