- Updated paths in test files to reflect new directory structure for RTL and script files. - Changed references from rtl/mini to rtl/ip and scripts/rtl where applicable. - Added a new test file for Tiny product isolation, ensuring independent ABI and bus acceptance. - Enhanced tests for memory map generation and protocol contracts for Tiny architecture. - Ensured that all tests are aligned with the latest directory structure and naming conventions.
