It seems that S32DS for PPC has been missing on S32DS official page.
where can I find the official download link?
Please check the download section of S32 Design Studio. S32DS Power v1.1 is now back and available for download.
We apologize about the delay and thanks for your patience!
I quote stanish answer from another post here at community.
"S32 Design Studio for Power Architecture has been intentionally removed since we spotted an issue that requires an immediate fix.The installer will be back on the web in about a week."
We are sorry for any inconvenience.
