Known Limitations with Design

The service SetRamblockStatus is used instead Per Instance memory “SetRamBlkSts “ as there is no concept of transition function in EA4. So SetRamblockStatus() is called and set to true whenever SetRamBlkSts PIM is made as True.

Peer Review Summary Sheet

Synergy Project Name:

kzshz2: Intended Use: Identify which component is being reviewed. This should be the Module Short Name from Synergy Rationale: Required for traceability. It will help to ensure this form is not attaced to the the wrong change request. SF051A_SnsrOffsLrng_Impl

Revision / Baseline:

kzshz2: Intended Use: Identify which Synergy revision of this component is being reviewed Rationale: Required for traceability. It will help to ensure this form is not attaced to the the wrong change request. 1.2.0

Change Owner:

kzshz2: Intended Use: Identify the developer who made the change(s) Rationale: A change request may have more than one resolver, this will help identify who made what change. Change owner identification may be required by indusrty standards. Nick Saxton

Work CR ID:

EA4#6809

kzshz2: Intended Use: Intended to identify at a high level to the reviewers which areas of the component have been changed. Rationale: This will be good information to know when ensuring appropriate reviews have been completed. Modified File Types:

kzshz2: Intended Use: Identify who where the reviewers, what they reviewed, and if the reviewed changes have been approved to release the code for testing. Comments here should be at a highlevel, the specific comments should be present on the specific review form sheet. Rationale: Since this Form will be attached to the Change Request it will confirm the approval and provides feedback in case of audits. ADD DR Level Move reviewer and approval to individual checklist form Review Checklist Summary:

Davinci Files

Comments:

Only reviewed changes

General Guidelines: - The reviews shall be performed over the portions of the component that were modified as a result of the Change Request. - New components should include FDD Owner and Integrator as apart of the Group Review Board (Source Code, Integration Manual, and Davinci Files) - Enter any rework required into the comment field and select No. When the rework is complete, review again using this same review sheet and select Yes. Add date and additional comment stating that the rework is completed. - To review a component with multiple source code files use the "Add Source" button to create a Source code tab for each source file. - .h file should be reviewed with the source file as part of the source file.
