Had a look over "DO-254 explained" document [1]. We can consider two types of traceability it seems:
Note that by "component" I mean a "unit of review of verification". So examples of components are: a code block, or a TLA+ module, or an English spec defining a problem abstractly.
Thanks for the pointer!
I guess the main problem is combination of the two types. E.g., if I have some temporal property A, and then in the process of refinement I figure out that A needs to be rewritten, I have to update to A2. Now it becomes complicated if other components use A. Should A still be there and A2 added, etc. In order even to understand the situation, it would be important to understand what components refer to A. For that the matrix of which Igor talks about would be important...
I think I have a clear idea in my head now. So I have started writing a proposal.
