Configuration used

1. Env configuration
2. Master Agent configuration
3. Slave Agent configuration

Master agent configuration

Table 5.2 Master_agent_config |Name |Type |Default value| Description| |-|-|-|
|is_active|enum |VM_ACTIVE It will be used for configuring an agent as an active agent means it has sequencer, driver and monitor or passive agent which has monitor only.|
|no_of_slaves |integer |‘d1 Used for specifying the number of slaves connected to the master|
|has_coverage |integer |‘d1 Used for enabling the master agent coverage|

Slave agent configuration

Table 5.3 Slave_agent_config

|Name| Type| Default value |Description| |-|-|-| |is_active enum UVM_ACTIVE It will be used for configuring agent as an active agent means it has sequencer,driver and monitor and if it’s a passive agent then it will have only monitor slave _id integer ‘d0 Used for indicating the ID of this slave e.g. slave 0 is selected. has_coverage integer ‘d1 Used for enabling the slave agent coverage.
