1.5.4. Overlapping Simulations

You can perform a simulation on the entire design, and more exhaustive simulations on a submodule, such as 8b10b_rxerr. The following table lists the import specification for overlapping simulations.

In this case, the software uses signal activities from error_cases.vcd for all the nodes in the generated .vcd and uses signal activities from full_design.vcd for only those nodes that do not overlap with nodes in error_cases.vcd. In general, the more specific hierarchy (the most bottom-level module) derives signal activities for overlapping nodes.
