 | `starttime` | `float` | Timestamp of start-up of the system (return value of `time.time()`) |
+| `default_compiler_config` | `dict[str,list[dict[str, Any]]]` | Compiler configurations for different stages. Keys represent stage names (e.g., "decomposition"), and values are list of passes. Each pass includes settings such as the pass name, corresponding method invoked by opensquirrel and additional keyword arguments. |
