TM is mapping between Specifications and test cases
CM is mapping between Specifications and Maps(Design maps)

I did not understand the word cross refferance matrics.

The test-requirements cross-reference matrix shows how every requirement listed in the SRS will be tested. In some cases, this can be arranged in the form of a table. In other cases, bullet lists provide a better approach to presenting the information in a readable form. Ideally, there will be a straightforward relationship between requirements in the SRS and the tests, with every test motivated by requirements in the SRS and every part of the SRS corresponding to one or more of the tests.The following gives a reasonable set of information that can be provided for each requirement in the matrix: * The unique identifier for the requirement (probably the specific paragraph number from the SRS where the requirement is first described) * A brief description of the requirement * The means by which the requirement will be tested (e.g. analysis, inspection, demonstration, test data) * Specific variables that are associated with the requirement * Ranges of values for the variables * System functionality associated with the requirement * Any comments

Tracability Matrix: The traceability matrix ties individual requirements in the SRS both to specific paragraphs in the SDS and to specific lines in the pseudocode. The objective of the traceability matrix is to assure that all requirements listed in the SRS have been addressed in the design.A good method for presenting the traceability matrix is as a table. Use the paragraph numbering from the documents to make the references to individual requirements and parts of the SDS unambiguous. Ideally, there will be a straightforward relationship between SRS contents and the SDS contents, with all parts of the SDS motivated by requirements in the SRS and every part of the SRS corresponding to something in the SDSCross Referance Matrix: The test-requirements cross-reference matrix shows how every requirement listed in the SRS will be tested. In some cases, this can be arranged in the form of a table. In other cases, bullet lists provide a better approach to presenting the information in a readable form. Ideally, there will be a straightforward relationship between requirements in the SRS and the tests, with every test motivated by requirements in the SRS and every part of the SRS corresponding to one or more of the tests.To ensure all functional requirements have been captured in the detailed design, cross-reference each functional requirement with it?s associated Detailed Design element.
