2.1.1 Saving of Build Options IEEE71689, IEEE71695, ARINC/626 and ARINC/626-3

The Compile, Signal Flow Analysis and Signal Resource Allocation build options are saved in the object files and will be displayed by in the ACL Listing as follows:

Compile – s
Flow - <none>
Alloc - lvpx

The purpose was two fold.

• The Switch Server capabilities introduced in compiler release 20041216 (3.22.7) is enabled by usage of the’q’ option in the compile phase. In order for the Signal Resource Allocator to complete switching code without duplication knowledge of the compiler ‘q’ option was required.
• Investigation of user problem reports often requires that the ‘build’ options be known, recording that information in the object file will enable that information to be made available.

2.1.2 CRATE Digital Arithmetic

The legacy CRATE environment allowed the addition and subtraction of arbritary sized DIGITAL variables. Previous releases of the PAWS CRATE ATLAS compiler allowed such arithmetic only on DIGITAL variables that were less-than-or-equal to 32 bits in width. This release of the PAWS CRATE ATLAS compiler and release 1.30.0 of the PAWS Studio, specifically the WRTS, supports the addition and subtraction of DIGITAL quantities up to the maximum width allowed of 255 bits. If the width of the two operands differ the compiler will move that operand which is smaller to a temporary variable that has the width of the larger operand, thus the actual operation always occurs upon operands of the same width. Care should be taken that the result of either the addition or subtraction operation can be represented in the number of bits available. If overflow or underflow does occur then the result will be truncated.

To ensure backwards compatibility the Atlas, other options ‘p’ has been added. If the ‘p’ option is not selected then the above described processing will occur. However if the ‘p’ is selected then the processing will be identical to previous compiler releases. That processing was for operands less-than-or-equal to 32 bit to convert the DIGITAL operands to and INTEGER, perform the arithmetic, and convert the result back to a DIGITAL of the appropriate size. For operands greater-than 32 bit to issue an ERROR message.

2.1.3 IFTE Graphics Viewer Auto Label

The property LABELELEMENTS has been added to the IFTE Graphics Viewer. If set then all elements within a GED file that are not labeled will be labeled. That label will consist of the concatenation of the XML element attribute and value.

Example:

<PolyLine polyLineNumber="2">

would be labeled "polyLineNumber2"

Since within a frame the attributes use unique numbers then the GroupList attributes or labels are ignored.

This feature is provided as a debug aid to determine the source of a displayed GED graphics element when used with the SHOWLABEL property. It is not

05-999 IFTE Graphics Viewer

GED file text elements that consisted of blank characters only resulted in the creation of empty string text elements. Whilst text elements can be updated the size is fixed at the time of creation. As a result the display would always be empty.

This release of the IFTE Graphics Viewer corrects the problem.
