Model.rtw File Contents — System Record
In general, a model can consist of multiple systems. There is one system for the
root and one for each nonvirtual subsystem. Each descendent system of the root
system is written out using Pascal ordering (deepest first) to avoid forward ref-
erences. Within each system is a sorted list of blocks.
