| Electrical Analysis
|
We thoroughly conduct the following analyses to ensure that our products meet electrical specifications and achieve
optimum performance. With well-experienced engineers and high standard analysis procedures, we work closely with
R&D teams for debugging to provide high performance products to customers. |
| • Impedance Analysis |
|
We apply TDR (Time Domain Reflection) to measure PCB impedance.
|
| • Audio Quality Analysis |
| We analyze audio quality of platforms while recording and playing sound within an audio frequency band to ensure that the system can meet high quality audio requirements. |
| • Video Analysis |
|
We analyze the analog and digital video output signal quality to ensure that the system can effectively display videos and images.
|
| • Digital Signal Analysis |
|
We analyze the parameters of a digital signal (frequency, spread spectrum, amplitude, ring, overshoot, undershoot, rise time and fall time, jitter, setup time and hold time, timing sequence, bit error rate, etc. ) to ensure that the system works properly.
|
| • Power Noise Analysis |
|
We analyze the noise of each power rail to ensure that the system is stable.
|
| • Component Analysis |
|
We analyze each component of the platform to check if it meets relevant voltage, current, and temperature specifications.
|
| • System Stability Analysis |
|
We ensure the system stability and compatibility with different CPUs and memories in corner conditions (over-clock and reference voltage level changes).

| Signal Integrity Simulations |
We apply signal integrity and power integrity driven design processes to overcome the challenges of product design. Signal
integrity simulations help connect logic design and physical routing design. Based on the simulation results, we
develop routing guidelines to meet the AC/DC specifications for each high-speed digital signal. Signal Integrity
simulations help us shorten the design cycle, solve possible issues, and minimize resource consumption prior to
prototype development. |
| • Pre-Route Simulation |
|
Collect interconnection models, including IC models, package models, connector models, and cable models. Apply corner case simulations to find the solution space. Generate routing constraints. Predict the signal integrity for multi-board design.
|
| • Post-Route Simulation |
|
Validate the routing results. Provide suggestions of register setting for better signal quality. Predict electrical or routing changes.
|
| • Correlation |
|
Compare the measurement results and simulation results. Validate simulation model and methodology.
