This virtual method is used to enable/disable the trace capability. The base class implementation always returns 0, indicating that this feature is disabled. Extended classes wishing to support this feature must consider whether this feature should always be enabled, be enabled for all instances of the extended class, or enabled on a per instance basis. This method, and any supporting data fields, etc., in the extended class should be implemented in accordance with these decisions.

Returns the data in the data_to_pack[] field as a byte stream based on the burst_type. The assumption is that either data[] or cache_write_data[] fields of this class have been passed as arguments to data_to_pack[] field. In the case of WRAP bursts the data is returned such that packed_data[0] corresponds to the data for the wrap boundary. In the case of INCR bursts, the data as passed in data_to_pack[] is directly packed to packed_data[]. data_to_pack - Data to be packed packed_data - [] Output byte stream with packed data |

Returns a string (with no line feeds) that reports the essential contents of the packet generally necessary to uniquely identify that packet.
prefix - (Optional: default = "") The string given in this argument becomes the first item listed in the value returned. It is intended to be used to identify the transactor (or other source) that requested this string. This argument should be limited to 8 characters or less (to accommodate the fixed column widths in the returned string). If more than 8 characters are supplied, only the first 8 characters are used. hdr_only - (Optional: default = 0) If this argument is supplied, and is '1', the function returns a 3-line table header string, which indicates which packet data appears in the subsequent columns. If this argument is '1', the prefix argument becomes the column label for the first header column (still subject to the 8 character limit). | ||||

Returns 1 if the transfer crosses the byte boundary and returns 0 if transfer does not cross byte boundary This function determines if the transfer is unaligned, whether splitting the transfer is required based on the data width and remaining byte lanes available to access. Eg: If a 32-BIT SINGLE burst transfer with address 0x1003 is driven on 64-BIT data width, even the transfer is unaligned, the transfer can be proceeded in one transfer without splitting transfer based on the unaligned address.

When a multi-layer interconnect component is used in a multi-master system, it can terminate a burst so that another master can gain access to the slave The slave must terminate the burst from the original master and then respond appropriately to the new master if this occurs. This variable indicates burst terminated at Slave VIP when svt_ahb_system_configuration :: ahb_lite_multilayer is '1' This is set to '1', when termination of burst occurs. Slave VIP also updates the svt_ahb_transaction :: status as ABORTED. If svt_ahb_slave_configuration :: rebuild_after_multilayer_interconnect_termination is set to '1', the slave VIP waits for the rebuilding of the aborted transaction. The variable or the Multilayer Interconnect Termination feature is supported only at slave end.

Variable that holds the object_num of this transaction. VIP assigns a unique number to each transaction it generates from analysis port. This number is also used by the debug port of the VIP, so that transaction number can be displayed in waveform. This helps in ease of debug as it helps to correlate the transaction displayed in log file and in the waveform.
