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. CM670A_HwAg1Meas_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. 1.8.1

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. Krishna Anne

Work CR ID:

EA4#6437

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:

Comments:

Reviewed changes only, made port interface correction for a client, no functional 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.

Appendix

SENT2SPCO port out should be configured to be high level on port configurations refer CM10 for SPCO port configuration (SENT2SPCO shall be port level high). port configuration SENT2SPCO output:port (that’s needs to be configured as SENT2SPCO) should be initialized as input dio with level high.the client call Iohwab_Setfctprphlhwag1_oper will reset the pin to output alterante mode for SENT2SPCO

Design Recommandation :

- Port Config RSENT2 IO pin shall setup default input.

- Schedule execution of tasks as per below order at the end of 2ms task

1. "HwAg1MeasPer2"

2. "HwAg1MeasPer3"

3. "HwAg1MeasPer4"

4. "HwAg1MeasPer1"

- Schedule "HwAg1MeasPer4" & "HwAg1MeasPer1" shall at least 110us apart.

Design Rationale:

The implementation brings in the block “HwAg1Final” inside the True Condition of the “finalAbsAg” as the other error condition will just retain the previous value and rolling counter will not change. It saves extra instructions in the implementation to the match the FDD. Final Functionality is still the same.

Module Internal (Local) Functions

Local Function #1

Description

The implementation deviates from the FDD block “Intpn” block. The implementation finds the minimum of absolute values of the difference between HwAg1Step with all the values from the Calibration table and find the index associated with minimum value of the difference in the calibration table.

Local Function #2

Design Rationale

This function can be used both for read-and-use and for read-and-discard

Transition Functions

None

Known Limitations with Design
