In sourcelink, I can only see IUS5.83 and newer version.
How about the 5.5, 5.6, 5.7 and 5.8?
anyone has idea?
Short answer: you can't see them because they're end-of-lifed.
Log into sourcelink and have a look through the Release
Orderability and Support Lifecycle (via the Cadence Product and Release Lifecycle page)
