 ## Errors
 
-Tools should report errors to the user using the `ord::error` function
-defined in `include/openroad/Error.hh`. `ord::error` throws
-`ord::Exception`. The variables `ord::exit_on_error` and
-`ord::file_continue_on_error` control how the error is handled. If
-`ord::exit_on_error` is `true` then OpenROAD reports the error and exits. If
-the error is encountered while reading a file with the `source` or
-`read_sdc` commands and `ord::file_continue_on_error` is `false` then no
-other commands are read from the file. The default value is `false` for both
-variables.
+Tools should report errors to the user using the logging infrastructure
+described in the [Logger guide](Logger.md). The `utl::error` function
+throws an exception that is caught at the Tcl command level. The variables
+`exit_on_error` and `file_continue_on_error` control how the error is
+handled. If `exit_on_error` is `1` then OpenROAD reports the error and
+exits. If the error is encountered while reading a file with the `source`
+or `read_sdc` commands and `file_continue_on_error` is `0` then no other
+commands are read from the file.
