Upgrade and Compatibility Information

 The following section describes compatibility breaks, and workarounds where available

Package Compatibility Keys

The packages comprising the XDCtools release are uniquely identified by a compatibility key defined in the package.xdc file of a package. Please note that the package compatibility keys are independent of XDC product release numbers.

Package compatibility keys are intended to:

  1. Enable tooling to identify incompatibilities between components, and
  2. Convey a level of compatibility between different releases to set end user expectations.

Package compatibility keys are composed of 4 comma-delimited numbers - M, S, R, P - where:

Known Issues

ECL280863xgconf: If instances have required args, should force user to enter something
ECL280869xgconf: Can create two instances with the same name
xgconf does not respond to config file rename
ECL321074xgconf and XDCtools error parser add duplicate errors to Problems view

Editing RTSC .cfg file while using ROV can cause Java out of memory error

The RTSC editor for .cfg files (
XGCONF), and the Runtime Object Viewer debug window (ROV) both consume a lot of Java heap memory. Using both at the same time, or editing multiple .cfg files at the same time, can cause CCS (v4 or v5) to run out of Java heap memory and crash during heavy use. Workaround is to edit only one .cfg file at a time, and close XGCONF while using ROV.

Version Information

All releases have 4 digits (M.mm.pp.bb). This includes GA and pre-releases (engineering, EA  etc.). Pre-releases are denoted with a suffix (e.g.

This product's version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and b is an unrestricted set of digits used as an incrementing build counter.

To support multiple side-by-side installations of the product, the product version is encoded in the top level directory, ex. xdctools_3_15_00_50.

Subsequent releases of patch upgrades will be identified by the patch number, ex. XDCtools with directory xdctools_3_15_01_67. Typically, these patches only include critical bug fixes.

Please note that version numbers and compatibility keys are NOT the same. For an explanation of compatibility keys, please refer to the 'Upgrade and Compatibility Information' section.
