default svt_ahb_slave_transaction_base_sequence This sequence raises/drops objections in the pre/post_body so that root sequences raise objections but subsequences do not. All other svt_ahb_slave sequences in the collection extend from this base sequence. --
default svt_ahb_slave_controlled_response_sequence Abstract: class svt_ahb_slave_controlled_response_sequence defines a sequence class that provides slave response to the Slave agent present in the System agent. The sequence receives a response object of type svt_ahb_slave_transaction from slave sequencer. The sequence class then randomizes the response with constraints and provides it to the slave driver within the slave agent. The sequence also instantiates the slave built-in memory, and writes into or reads from the slave memory. --
default svt_ahb_slave_controlled_split_response_sequence Abstract: class svt_ahb_slave_controlled_split_response_sequence defines a sequence class that provides slave response to the Slave agent present in the System agent. The sequence receives a response object of type svt_ahb_slave_transaction from slave sequencer. The sequence class then randomizes the response with constraints and provides it to the slave driver within the slave agent. The sequence also instantiates the slave built-in memory, and writes into or reads from the slave memory. --
default svt_ahb_slave_memory_response_sequence Abstract: Class svt_ahb_slave_memory_response_sequence defines a sequence class that provides slave response to the Slave agent present in the System agent. The sequence receives a response object of type svt_ahb_slave_transaction from slave sequencer. The sequence class then randomizes the response with OKAY response and provides it to the slave driver within the slave agent. The sequence also instantiates the slave built-in memory, and writes into or reads from the slave memory.

default svt_ahb_slave_transaction_distributed_random_sequence This sequence generates distributed random svt_ahb_slave transactions. --
default svt_ahb_slave_transaction_error_sequence This sequence generates ERROR responses. --
default svt_ahb_slave_transaction_memory_sequence This sequence gets the slave response sequence item from slave sequencer. The slave response is then randomized based on certain weights. User can modify these weights such that the sum of all the weights is 100. Also the sequence provides additional level of control interms of maximum number of non-OKAY responses to be allowed on per full AHB transaction. The sequence uses the built-in slave memory. For read transactions, it reads the data from the slave memory. For write transactions, it writes the data into slave memory. The randomized response is then provided to the slave driver.

This sequence runs forever, and so is not registered with the slave sequence library.

default svt_ahb_slave_transaction_okay_sequence This sequence generates OKAY responses. --
default svt_ahb_slave_transaction_random_sequence This sequence generates random svt_ahb_slave transactions. --
default svt_ahb_slave_transaction_retry_sequence This sequence generates RETRY responses. --
default svt_ahb_slave_transaction_split_sequence This sequence generates SPLIT responses. --
