1.0 INTRODUCTION
AND SUINARY This document summarizes the results of the Phase I Design Qualification ~ Testing of a change to the CPC and CEAC sof tware for SONGS 2 Cycle 1.
The program affected by this change, which is describea in Section 2.0, was recuired to undergo Phase I Testing in accordance with Reference 2.
The change reflects the implementation of Software Change Recuest 244. This change was made in accordance with Reference 2.
The tests reported herein were conducted on the CPC/CEAC design. A discussion of the test configuration, test methodology, and test results are presented in this document.
1.1 OBJECTIVE OF PHASE I TESTING i
The objective of Phase I Design Qualification Testing is to verify the implementation of the Core Protection Calculatir" System (i.e., both CPC and CEAC) sof tware.
1.2 RESULTS I
Analysis of the Phase I Design Qualification Tests demonstrated that-the sof tware change had been correctly implemented to meet the system l
functional requirements.
1.3 CONCLUSION
S CPC System Chase I Testing was perforced in tne prescribed manner as described by Phase I Test P.rocedures. The Phase I testing _was
()
adequate to meet all of the test objectives. The success of the Phase.
I Testing demonstrates the adequacy of the CPC/CEAC software-implementation.
1.4 PREREQUISITES Before formal Phase I Testing was initiated, the following prerequisites were satisfied:
1.
Programmer debug testing was performed on the module changes to remove all obvious errors.
2.
The modules and programs that changed were integrated into complete sof tware systems and absolute core images were generated on the CPC permanent mass storage medium (floppy disks).

S 3.0 APPLICATION PROGRAM TESTING As described in Section 2.0 there were no changes to the CPC/CEAC applications programs and therefore the disk tracks containing the application programs sof tware were duplicated from the previous reference disk to the new. disk.
This duplication removed the requirement of retesting of the CPC/CEAC application programs as described in the CPC/CEAC Phase I Test P rocedu re.

r 4.0 EXECUTIVE TESTING The CPC/CEAC Executive software was tested in accordance with the CPC/CEAC Executive Phase I Test Procedure. This section discusses the actual test configuration, test cases, and test execution and results.
4.1 TEST CONFIGURATION l
Phase I testing of the CPC/CEAC Executive was performed on the CPC Single Channel System. For the purpose of this testing, the single channel was configured with the hardware ccmolement listed in Table d-l 1.
This hardware configuration is functionally identical to the as-built CPC/CEAC design.
The sof tware configuration for the Executive Phase I Testing is shown in Figure 4-1.
Memory was loaded with this configuration by the l
following procedure:
1.
An integrated CPC/CEAC systen was loaded frcm S0!!GS 2 Reference Disk #S110 (the entire image was loaded although only the l
Executive system is tested).
2.
The Interdata Hexadecimal Debug Program, CLUB, was loaded from magnetic tape overlaying an unused area in memory.
The prescribed test cases were then set up and executed using the CLUB program to test the Executive sof tware.
4.2 TEST CASES The CPC/CEAC Executive Phase I Test Cases are described in the Executive Phase I Test Procedure.
It was verified by automatic comparison that only track 6 was affected by the change described in Section 2.0 and thus testing was limited to this track as prescribed in the Phase I Executive Test Procedure.
Sufficient test cases were chosen to exercise each functional branch on track 6 of the Executive system.
4.3 TEST EXECUTION AND RESULTS For testing of the CPC/CEAC Executive, the debug program, CLUB, was used to insert test case inouts into memory; to insert breakpoints to trace and intercept code executions; and to exanine results.
Documentation produced as a result of Executive Phase I Testing consists of the CLUB teletype printouts, initialed and dated by the test engineer.
The CPC/CEAC Executive was tested on November 9 through November 10, l
1981. No errors were detected. - _ _ _ _ _ _ _ _ _ _

5.0 PHASE I TEST RESULTS SUf'!1ARY Phase I testing of the CPC and CEAC sof tware for S0!!GS 2 Cycle 1 was performed in accordance with Reference 2.
Test results conclude that the sof tware modification described in Section 2.0 was correctly l
[
implemented.
