I Can Monitor and Analyze eSPI Traffic from an Actual Device– Can I also Simulate a Master Device for a Prototype System?

▤ Summary

The eSPI bus generally works at bit rates of 20, 25, 33, 50 and 66 MHz, in single, dual, quad IO modes. To support this range of speeds and modes, we recommend using the SPI Active - Level 3 Application for the second Promira platform. Here are limitations you should be aware of: • Simulating eSPI mastering is only supported when using a second Promira platform with the appropriate SPI Active Level applications. • The eSPI software examples that we provide are only available in the software language Python: • espi_simulator provides basic eSPI functions, including sending resets, alerts and get status, configuring the I/O mode for single, mode, or quad, deliver messages to slave devices, and more We hope this answers your question. Additional resources that you may find helpful include the following: If you want more information, feel free to contact us with your questions, or request a demo that applies to your application.
