12.3.3.1. Read and Write Generation

The traffic generator block can generate individual or block reads and writes.

Individual Read and Write Generation

During the traffic generator’s individual read and write generation state, the traffic generation block generates individual write followed by individual read Avalon-MM transactions, where the address for the transactions is chosen according to the specific substate. The width of the Avalon-MM interface is a global parameter for the driver, but each substate can have a parameterizable range of burst lengths for each operation.

Block Read and Write Generation

During the traffic generator’s block read and write generation state, the traffic generator block generates a parameterizable number of write operations followed by the same number of read operations. The specific addresses generated for the blocks are chosen by the specific substates. The burst length of each block operation can be parameterized by a range of acceptable burst lengths.
