Module Internal (Local) Functions

Local Function #1

Design Rationale

This function is split from Per1 to reduce path count and cyclomatic complexity.

Local Function #2

Design Rationale

This function is split from Per1 to reduce path count and cyclomatic complexity.

Local Function #3

Design Rationale

This function is split from Per1 to reduce path count and cyclomatic complexity.

Known Limitations with Design

None.

UNIT TEST CONSIDERATION

1. Clear local buffer in the below path of the model has not been implemented, because it’s not required. Path : ES225A_HwTq10Meas/HwTq10Meas/HwTq10MeasPer1/Raw Data Processing/Clear Local Buffer
