This approach to tracking simulation time was a mistake that I did not catch in review. It has several issues: 1. There is absolutely no requirement to call `step()`, as it is a convenience function. In particular, `steps` will not be incremented in submodules if `-noflatten` is used. 2. The semantics of `steps` does not match that of the Verilog `$time` construct. 3. There is no way to make the semantics of `%t` match that of Verilog. 4. The `module` interface is intentionally very barebones. It is little more than a container for three method pointers, `reset`, `eval`, and `commit`. Adding ancillary data to it goes against this. If similar functionality is introduced again it should probably be a variable that is global per toplevel design using some object that is unique for an entire hierarchy of modules, and ideally exposed via the C API. For now, it is being removed (in this commit) and (in next commit) the capability is being reintroduced through a context object that can be specified for `eval()`. |
