Changes to Cadence products are identified by a Cadence Change Request (CCR). A CCR is a unique identifier and tracking mechanism within the Cadence Change Management System (CCMS) to document a product issue or enhancement. CCRs are identified by a unique number in the CCMS database and this is cross-referenced to a Service Request. CCR status is viewable on Cadence Online Support.

Severity is an objective indicator of how bad a problem is technically. Severity is an attribute of the problem itself as characterized by Cadence and the requester and has the following 3 levels of distinction.
- 0 - No Workaround ("S0")
| - |
A production-stopping software bug with no workaround that is acceptable to the customer |
| - |
Associated Service Request remains open until the CCR is resolved and customer has confirmed the fix |
| - |
For faster resolution of your issue, please provide a test case to the SR owner |
- 1 - Workaround ("S1")
