- Introduced the PPALite extension, approved on 2026-10-05, detailing its features such as camera-inline Y extraction, RGB565 ordering, and fixed pixel/line sampling.
- Updated the tiny-soc-verification and tiny-soc documentation to reflect the new PPALite extension, including its integration with existing DVP and DMA channels.
- Added comprehensive evidence tables for PPALite phases (PPALITE-P0 to P5) outlining required evidence and current statuses.
- Clarified the relationship between PPALite and existing SPI/PIO extensions, emphasizing that earlier results cannot qualify newly added PPALite logic.
- Enhanced the README files in the RTL directory to specify PPALite's role and requirements in the context of Tiny SoC development.
- Introduced the separately approved SPI extension (2026-10-04) for the Tiny SoC, detailing the addition of SPI0 as a master-only controller with 8/16-bit capabilities.
- Updated documentation to reflect the SPI phases (SPI-P0 to SPI-P5) and their respective requirements, including DMA V2.2 pacing and fixed-MMIO requests.
- Specified GPIO assignments for SPI functionality, including the use of previously reserved Gen1 ALT routes.
- Clarified the integration boundaries and dependencies on existing R2 and PIO-lite phases, emphasizing the need for complete implementation before qualification.
- Documented the implications of SPI integration on existing GPIO and DMA channels, ensuring no additional resources are allocated without proper validation.
- Updated the verification ledgers to track pending evidence and implementation gaps for both SPI and PIO-lite extensions.
- Updated the tiny-soc-verification.md to clarify the separation of PIO-lite as a standard-product extension, detailing its planned features and evidence requirements.
- Revised tiny-soc.md to emphasize the historical context of the R2 design freeze and the independent nature of the PIO-lite extension, including its integration requirements and phase structure.
- Added details in soc-family-positioning.md regarding the PIO-lite extension's capabilities and its distinction from the R2 performance-only approval.
- Enhanced README.md files in rtl/ip and rtl/tiny to reflect the future integration of the PIO-lite extension, specifying its features and the implications for existing RTL and DMA configurations.
- Introduced to define formal properties for the DMA design, ensuring correct behavior under various conditions.
- Created as a testbench for the DMA register interface, implementing APB and AXI4 protocols to validate register operations.
- Added to verify synchronization between RTL and SDK register constants, ensuring consistency across implementations.
- Updated filelist to include I2S related files.
- Enhanced formal file generation script to support I2S target.
- Introduced I2S formal design and properties for verification.
- Modified formal makefile to include I2S targets and source files.
- Added I2S related source files to software build.
- Updated style audit to include I2S files.
- Implemented I2S helper functions in C tests.
- Created I2S testbench for RTL simulation.
- Added regression test for I2S controller functionality.
- Updated test files to change instances of ribp_if to apb4_if in various test cases, ensuring consistency with the new APB4 interface.
- Modified assertions and checks in tests to reflect the new APB4 naming conventions, including changes in expected output and input files.
- Adjusted the test descriptions to accurately represent the APB4 functionality being tested, particularly in timer, UART, and GPIO tests.
- Ensured that all relevant paths and file names in the tests are updated to point to the new APB4 implementations, maintaining the integrity of the test suite.
- Introduced a new testbench for the AXI4 interconnect () to validate fault classification for decode and access errors.
- Updated and to reflect changes in bus naming conventions.
- Enhanced to include AXI4-Stream interface checks and validate stream data transfers.
- Modified to integrate AXI4-Stream interfaces for improved DMA testing.
- Added new Python tests () to verify AXI4 to RIBP burst bridge functionality and interconnect fault classification.
- Updated existing tests to include AXI4 interfaces and ensure proper error handling and response validation.
- Adjusted memory map generation and test setups to accommodate new AXI4 interface requirements.
