- 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.
Tiny MCU Integration
Tiny is the independent single-Hazard3 wired MCU product. Its frozen contract
is Tiny MCU. Use
make CONFIG=configs/ci/ihp130-tiny.mk setup followed by
make CONFIG=configs/ci/ihp130-tiny.mk firmware sim.
top owns product integration, address_map, pin_map and integration own
canonical address, pad, IRQ and clock/reset inputs, filelist selects sources,
dv owns product verification, and mk owns product configuration. Reusable
RTL lives in rtl/ip; Common and Hazard3 remain locked managed inputs.
No Tiny source list includes RIB/RIBP or Mini product RTL. Build rules invoke
shared helpers in scripts/rtl directly; generated files belong only under
the selected build variant.
The initial IHP130 profile has 128 KiB SRAM, 24 MHz AXI32/APB4, four DMA channels, and RV32IMC without atomics. Wireless, external RAM, HP cores and accelerators are outside this release. Run both Icarus and Verilator, the Tiny directed tests, and the IHP130 regression before claiming qualification. Synthesis and STA use the Tiny top and clock inventory, not Mini constraints.
make CONFIG=configs/ci/ihp130-tiny.mk regress-pr runs only Tiny's IHP130
matrix. The regression runner also accepts --soc TINY; leaving it unset
retains the combined Mini/Tiny IHP130 matrix. netsim-boot uses the compact
assembly SRAM/pad test, while netsim uses the full SDK acceptance image.
See the verification record for
qualification boundaries and the observed reset-distribution timing deficit.
