Hi TI experts,
I have completed my custom board schematics based on AM62x SOC. Could you guide me on reviewing the schematics.
Hi Board designers
We currently do not support schematics review over E2E.
You could do a self-review following the below steps that includes detailed custom board schematic design guidelines and schematics review checklist.
In case if you have additional queries, start an E2E thread for experts to support.
Below are the recommended steps to be followed for performing a self-review:
AM62X
Step-1: Design Guidelines to be followed for custom board design
Review the below collaterals and verify the custom board design follow these requirements/recommendations

During custom board design, customers tend to reuse the SK design files and make edits to the design file. Alternatively, customers reuse some of the common implementations including the SOC, memory and communication interfaces. Since the SK is expected to have additional functionalities, customers optimize the SK implementation to suit their board design requirements. While optimizing the SK schematics, errors get introduced into the custom design that could cause functional, performance or reliability issues. When optimizing customers have queries regarding the SK implementation resulting in design errors. Many of the optimization and design errors are common across designs. Based on the learnings and data sheet pin connectivity recommendations, comprehensive Design Notes (D-Note:), Review Notes (R-Note:) and Cad Notes (Cad Note:) have been added near each section of the SK schematic that customers could review and follow to minimize errors.
Step-2: Frequently Asked Questions FAQs - review relevant FAQs from the master list before completing the design
Step-3: Self-Review - Refer to the below documents and FAQs to perform a self-review
Once the custom board schematics design is complete following the design guidelines provided in the above application note and referring to the SK schematics (including the design notes and review notes) and other available collaterals, customer can do a self-review using the checklist provided at the end of each design guidelines section.
Example: Processor Core and Peripheral Core Power Supply Checklist, General Board Bring-up and Debug Checklist
Note on the checklist:
We now have an excel checklist that references the sections of the design guide and provides comprehensive list that can be used to review the custom board schematic design.
There is a Checklist_Summary tab that could be filled after reviewing each section to ensure review completeness as well as asking queries over E2E or referring to available collaterals for clarifications.
Refer Schematic Review Checklist for AM62x processor family (Recommended) section
Note:
Fill the Checklist_Summary Tab and share with the review request as required. The key to the Review Comments column headings is: NA, Not Applicable; NC, Not Checked; OK, Checked, Updated, need clarifications.
Add additional details when required.

Notes on the Processor Family Specific Application Note
This application note is for the AM62x family of processors covering AM625, AM623, AM625SIP, AM625-Q1, and AM620-Q1.
The application notes describe the schematic design guidelines and schematics review checklist for specific family of processor. A processor family specific application note simplifies the use of the chosen family of processors.
Schematics Design Guidelines
The application note provides guidelines for all the peripherals supported by AM62x processor family. Board Designers can review and follow schematic design guidelines during the custom board schematic design. Along with the guidelines, links to FAQs are provided for use during custom board schematic design, thus reducing effort and minimizing error.
Schematic Review Checklist
The section has been added to the application. All the relevant peripheral or power sections in the application note includes checklist categorized as General, Schematic Review, and Additional. Board Designers can use the checklist to do a self-review of the custom board schematics to minimize possible errors that can cause functional or performance issues resulting in increased board bring-up and testing time.
Notes on the Family of Processors Application Note
The application note covers AM623, AM625, AM625SIP, AM620-Q1, AM625-Q1, AM62A3, AM62A7, AM62A3- Q1, AM62A7-Q1, AM62D-Q1, AM62P and AM62P-Q1 processor families.
The application note covers the schematic design guidelines and schematic review checklist for the above family of processors. Application note for family of processors makes it easy to understand implementation differences when migrating from one family of processor to another family of processors or from one processor package to another package.
Step-4: Queries or Clarifications
In case you have additional queries reach out to local TI support you are working with or add an EE query.
Step-5: Submit Schematic review request
This is optional.
Work with TI local TI support you are working to submit schematics review request after doing a self-review and making the required updates
In case you do not have access to the TI sales, fill the Checklist_Summary tab of the schematic review excel checklist and share the schematics on E2E for a quick check. The timeline for the review is expected to be 2..3 weeks minimum and could be more based on the number of requests submitted.
