I ran into a compilation issue.
This link explains the problem well: https://stackoverflow.com/a/5499222/3736700
For example, in a header file, it is generally not considered a good idea to put the line using namespace std; (or to use any namespace, for that matter) because it can cause names in files that include that header to become ambiguous. In this setup, you would just #include <string> in the header, then use std::string to refer to the string type.
Add support for FSDB waveform dumping using existing API. Feature is enabled using +define+FSDB.
Change has not been fully regressed (i.e., please don't pull blindly). Impact on existing knobs is minimal, should not affect existing functionality. Automated Travis builds should be sufficient to assess.
Alternatively could using +define+VCS. Chose to introduce new define because multiple simulators support FSDB dumping.
