svt_ahb_system_random_sequence This sequence allows unconstrained random traffic for all ports
svt_ahb_system_base_sequence This sequence creates a reporter reference
svt_ahb_slave_transaction_sequence_library AHB VIP provides a pre-defined sequence library svt_ahb_slave_transaction_sequence_library, which can hold the AHB sequences. The library by default has no registered sequences. You are expected to call svt_ahb_slave_transaction_sequence_library :: populate_library method to populate the sequence library with svt_ahb_slave sequences provided with the VIP. The system configuration is provided to the populate_library method as an argument. Based on the configuration, appropriate sequences are added to the sequence library. You can then load the sequence library in the sequencer within the svt_ahb_slave agent.
svt_ahb_slave_tlm_response_sequence This sequence is used as Reactive seuqnce which translates slave transactions into corresponding AMBA-PV extended TLM Generic Payload Transactions and forwards it via the resp_socket socket for fulfillment by an AMBA-PV Slave. The response returned by the socket is then sent back to the driver.
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.
svt_ahb_slave_transaction_retry_sequence This sequence generates RETRY responses.
svt_ahb_slave_transaction_split_sequence This sequence generates SPLIT responses.
svt_ahb_slave_transaction_error_sequence This sequence generates ERROR responses.

svt_ahb_slave_transaction_random_sequence This sequence generates random svt_ahb_slave transactions.
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.
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.
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.
