Table 5-1 describes the parameter names for the data and ID signals and their default values.
A monitor BFM has configuration fields that set with the set_config() function to configure
timeout factors, setup and hold times, and so on. You get the value of a configuration field with
the
get_config() function. Table 5-2 describes the configuration fields.
