In the ServiceNow whitepaper, the CSDM is not a product or a solution that would do anything for you. It is just a model, albeit a very good one.
Some sophisticated tools can map application topologies (and call them service maps), but for now, there are always parts of the big picture that cannot be modelled and managed without human input.
In summary:
*Discovery tools can greatly assist with populating the CMDB
*Discovery tools cannot manage all data within the CMDB
*The CSDM provides a model, but not the means to link discovered data into the abstract data classes
*The Service Portfolio and some other logical elements (e.g. Business Applications) and other relationships to non-CMDB data e.g. users and org structure) need to be manually maintained
*You need to define and manage to relationships between discovered and manually maintained data
