This commit addresses several issues that can occur with different
simulators. It changes the following:
- Update documentation
- Ignore testbenches in build-ip folders
- Tolerate extra lines in the testbench results regular expression
- Match numbers using \d instead of + to avoid ValueError exceptions
- Only fetch the start_time if it exists
- Allow any simulator make target (don't limit it to specific choices)
