 Product Change Requests 

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.

CCR Severity

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")
    - A production-stopping defect with an acceptable workaround
    - Severely production limiting defect having negative impact on customer productivity
    - Associated Service Request remains open until it has been confirmed that the customer has been notified of the fix
  • 2 - Minor ("S2")
    - An enhancement to existing functionality that will improve the use of the product
    - Once assigned, Service Request is closed.
CCR Urgency

Urgency addresses the need for quicker than standard response and has the following 2 levels of distinction.
  • U - Urgent
    - Immediate help getting customer working is required
    - Issue is stopping tape out at the customer site
    - Issue has a significant financial impact on the customer and/or Cadence
    - Workaround is unacceptable to the customer because it requires many error-prone, often repeated, manual steps
    - Workaround adds significant time to customer's design efficiency
    - Performing the workaround requires additional engineering resources
  • D - Default
    - Fix needed when available under standard maintenance planning/fixing cycles
