- Updated dma_error_tb to implement burst transfer handling and performance measurement for INCR4 transfers. - Introduced rib_burst_bus_tb to validate RIB burst arbitration and protocol compliance. - Added soc_rib_burst_ram_tb to test SRAM behavior with burst commands. - Created spill_register_tb to verify the functionality of the spill register under various conditions. - Modified test_dma.py to reflect changes in DMA error handling and performance reporting. - Updated test_memory_map.py to include new RIB burst interfaces and spill register utilities. - Enhanced test_rib_burst.py with directed tests for RIB burst building blocks and spill register behavior. - Adjusted test_soc_topology.py to ensure correct instantiation counts for RIB interfaces. - Improved test_user_extensions.py to validate the generation of isolated scalar bindings for burst interfaces.
