10 Creating the Schematics

At this point in the design, it is time to start capturing the schematics. The following collection of information will aid you in creating the schematics:

• Key Considerations
  • Output clocks that are internally looped back
  • Do not forget to install a JTAG connection
  • JTAG: Make sure to use the RTCK pin on the JTAG connector. For more information, see the Emulation and Trace Headers Technical Reference Manual.
• It is helpful to refer to the EVM schematics (that can be downloaded from the EVM links listed above in Section 2) as examples throughout the schematic capture process:
• Make sure to use the canned schematics in the device-specific data sheet for the following interfaces:
  • DDR3/DDR3L
• For detailed information on USB, HDMI, SATA, and PCIe board design, see the High-Speed Interface Layout Guidelines
• During and after schematic capture, check your design against the schematic checklist:
  • AM57x Schematic Checklist
• Plan to have an internal review to go through the schematic checklist and inspect other key areas of the schematic to look for inaccuracies, missing net connections, and so forth.

Below is a list of additional aids available on the AM57xx device's product page that can be used during your schematic and board design:

• Altium symbols
• Pin names and numbers in the device-specific data manual:
• BSDL Simulation Models
• IBIS Simulation Models
