WEBENCH® Interface Designer

Quickly optimize signal integrity in high-speed designs

WEBENCH® Interface Designer creates an interface solution optimized for your system requirements using Texas Instruments state-of-the-art interface products. The Interface Designer can be used to create a new high-speed serial interface system or enhance the signal integrity of an existing system.

Key WEBENCH Interface Designer features:

  • Easily create new high-speed serial interface systems
  • Analyze and enhance signal integrity for existing designs
  • Select the right interface devices for your requirements

The signal flow diagram page of the Interface Designer helps you configure the signal flow diagram that represents your high-speed interface system. After the signal flow diagram is configured, the  Visualizer enables you to select the TI interface products based on your system criteria. You can adjust your selection preference to meet industry standard specification or your custom specification.

Once the preferred interface products have been selected, the Analyzer advanced signal integrity analysis tool validates the performance of your selected solution. The Analyzer can be used to
recreate your system channel behavior and verify that the selected products can help your system achieve the best signal integrity. You can also use the Analyzer to identify the optimal settings to enhance your system signal integrity.

Configure your signal flow diagram and start your interface design now

Step by Step:

1. Configure the signal flow diagram
Configure your signal flow diagram and specify the maximum data rate of your system. Then click “Start Interface Design” to advance to Input Selections screen

2. Enter your part selection criteria


Note: Click on the question mark for help

3. (Optional) Select a transmitter

4. (Optional) Select a signal conditioner

5. (Optional) Select a receiver

6. Click “Go to Simulation” button to perform signal integrity analysis

7. Configure the transmitters and simulator settings for signal integrity analysis

8. Change transmitter settings

Use tooltips to get guidelines for setting up parameters

9. Setup up-stream channel

10. Make changes to the channel

Upload or retrieve a custom channel on the leftSelect a channel based on length or loss on the right

11. Setup the rest of the components

12. Click “Run Simulation” to start the simulation

13. The streaming eye diagrams are incrementally updated during simulation

14. Use a reference eye mask… or…

… set up a custom eye mask. You can assign two edges to have the same point if you want to create a triangle mask

Congratulations! You just found a working solution

Feature Highlights:

1. Score: All parts are scored based on the relative equalization strength. You can easily re-select alternate part that has higher or lower equalization based on your system need

2. BER Extrapolation: You can use BER extrapolation to estimate the performance at lower BER to save simulation time. You can simulate a million bits (3 minutes) and use BER extrapolation to estimate performance @BER-12 instead of simulating 1012 bits (couple of hours)

3. High-Definition Eye-diagram: You can choose to view eye-diagram in HD or SD

4. Channel Viewer: You can view the detail characteristic of a channel

5. History Tab: You can retrieve previous simulation settings and results. You can also generate a pdf report for a simulation
