- Updated NMI interface references from to in multiple files for consistency. - Added a new script to convert UART performance records into structured JSON format. - Enhanced the README documentation to include details about the new performance log parser. - Implemented tests for the new performance log parser to ensure correct functionality. - Added new test cases for DMA error handling and SDRAM data integrity to improve coverage. - Updated existing test cases to accommodate changes in the NMI interface and added performance metrics. - Refactored bus fault testbench to include fault code checks and improved error handling. - Adjusted memory map generation and pin mapping tests to reflect recent changes in RTL structure.
