TOOL STATUS

This is a description of the software tools being developed to test ACIS flight software, to support ACIS EGSE, and to perform end-to-end tests of the instrument. It is a joint effort of the ACIS flight software and GSE teams, and includes a detailed description of the command and image definition languages and bit-level descriptions of the several interfaces between sub-components.

1.0 Introduction

The tools are divided into three categories: "GSE Transport Tools" are responsible for sending commands to the instrument and receiving telemetry in reply; "GSE Test Tools" generate the commands from human-readable scripts, interpret the telemetry packets, and analyze their contents; and "Image Tools" are responsible both for reading images from the analog units (DEAs) and for creating and writing images to the digital units (FEPs). The general relationship between these three tool groups is represented in Figure 1; the details are in Figure 2.

FIGURE 1. Test Tool Overview

The interface between the Image Tools and ACIS, the "Image Loader", is described in Section 8, and science data formats of use in analyzing the "GSE Test Tools" output are described in Section 9. Some alternative image tools are described in Section 10. The current status of tool development is shown in Appendix A.
