Signal Integrity / Simulation :

Simulation reduces product design cycle time

PCB design is no longer just the process of connecting the pins on a number of packages. Now, board design is subject to significant pre- and post-routing analysis for Signal Integrity, cross talk analysis, transmission line design, correct terminations, electro-magnetic interference (EMI), thermal, and manufacturing requirements.

The analysis require new tool capabilities to supplement the basic interconnect routing functions. Also, the disparity between the rate of change of silicon technology and the rate of improvement of design capability has greatly increased.

We have made significant investment into our SI infrastructure (tools, process, and expertise) to enhance our value add to you. With experienced engineering staff in-house, and state of the art SI tools, Simulation is another area where we outrival our competitors. Integration of SI practice with design and layout flow has paid big dividends on many projects. We offer multiple options depending on your overall project plan. Let your project benefit from our expertise.

Simulation involves the following aspects:

•  Pre Layout Simulation
•  Post Layout Simulation

In our SI approach we address the following areas:

•  Floor Planning analysis
•  Develop a set of constraints to be followed during routing
•  Topology Design
•  Transmission Line
•  Termination Design
•  Post Layout Verification
•  Timing
•  Net lengths
•  Cross Talk

Simulation can be as extensive as running simulation on multiple boards as a system, and it can be as simple as running simulation selectively on few critical lines depending on each project's requirements. We can identify the risk areas of the circuit, which will benefit from SI during the project planning phase. With proper planning, during the schematic phase, we can put together all the models required for simulation.
