Digital Pre-Distortion(DPD) v6.0 Patch
This patch resolves three issues associated with the DPD v6.0 software release and is designed to be fully backward compatible with v6.0 software.
The following issues have been resolved in this patch:
The v6.0 rev1 patch can be downloaded from DPD lounge:
The patch updates key files in the coregen directory of a Xilinx ISE 14.3 install. When using the default installation paths, this is found at:
The patch contains two further zip archives:
- dpd_v6_0_patch1_install.zip to install the patch
- dpd_v6_0_patch1_uninstall.zip to uninstall the patch (returns DPD to base ISE 14.3 release)
Extract the required install/uninstall zip file in a temporary folder. Then, install the patch by copying the coregen folder from the temporary folder over the top of the installed coregen directory above, selecting the option that allows the extractor to overwrite all of the existing files and maintain the directory structure predefined in the archive. This patch should only be applied to the base DPD v6.0 core. Therefore, if any previous patches have been applied, uninstall them before applying this patch.
Un-install the patch by extracting the coregen folder of the "dpd_v6_0_patch1_uninstall.zip" archive from temporary folder over the top of the installed coregen directory above, selecting the option that allows the extractor to overwrite all of the existing files and maintain the directory structure predefined in the archive. The uninstallation of this patch returns the DPD core to v6.0 (i.e. it does not downgrade to any previous patch levels).
Verifying Successful Installation
Successful installation of the patch may be verified by reading address 32 from the DPD host interface after the new core has been built. For the original DPD v6.0 release register 32 is 0x0600, and with the patch 1 installed register 32 is 0x0603.
