| | * | test(trap_ctrl): add store page fault unit test case | Richard Qin | 2026-03-31 | 1 | -2/+10 |
| |/ | | | | | | | | | Added a specific test scenario for Store Page Fault in tb/unit/tb_trap_ctrl.cc. - Defined EXC_STORE_PAGE_FAULT (15) constant. - Implemented a test case that asserts trap_store_page_fault and verifies mcause and mtval. - Improved clarity by renaming existing page fault test labels to LoadPageFault.

| | | | | | | | | | | | | | | | | | | acceptance tests - Refactor trap/CSR data path in the Core, unified with trap_ctrl interface to drive CSR update and return process - Improve critical paths for exception/interrupt handling: ecall, illegal, load fault, external interrupt, mret/sret return - Adjust pipeline stage registers with flush/stall coordination, fix residual control signal issues in trap scenarios - Enhance decode and related pipeline module behavior consistency, fill in missing control signal propagation across registers - Expand core integration testing, add trap/interrupt scenarios and CLI dispatch that can be executed per case - Extend CSR unit test coverage: read/write semantics, privilege switching, delegation and nested returns, illegal access protection, etc. - Register new core scenario cases in CTest to form a regression-capable P2 strict acceptance suite Verification: - Build passed - Full CTest passed (22/22) | ||||

| | * | test(core): fix WB stage tests after naming and logic refactor | Richard Qin | 2026-03-17 | 1 | -5/+8 |
| | | | | | | | | | | | | | | | | | | | - Renamed `wb_reg_write_data` to `wb_rd_wdata` in all assertions to match the updated module ports. - Renamed `wb_reg_write_addr` to `wb_rd_addr` in all assertions. - Initialized the new `mem_wb_pc_plus_4` input in the testbench setup to correctly test the JAL/JALR datapath. - Added assertions to explicitly test that `wb_reg_write_en` and `csr_req` are gated when an exception occurs.

| | * | refactor(core): address WB stage architectural and naming review feedback | Richard Qin | 2026-03-17 | 1 | -12/+17 |
| |/ | | | | | | | | - Renamed `wb_reg_write_data` and `wb_reg_write_addr` to `wb_rd_wdata` and `wb_rd_addr` respectively to comply with `docs/naming_convention.md`. - Removed the 64-bit adder for `mem_wb_pc + 64'd4` from the WB stage to improve timing. Introduced a new `mem_wb_pc_plus_4` pipeline input instead. - Added a `has_trap` signal to gate architectural state updates (`wb_reg_write_en` and `csr_req`) upon exceptions, ensuring precise exceptions without corrupting the register file or CSRs.
