The work done here makes it straightforward to regenerate RTL, run full unit and fuzz tests, and add this component into a larger SoC flow. + +**Highlights / Why this matters** + +- **Full Chisel implementations:** Completed `PlicCell`, `PlicGateway`, `PlicTarget`, and `PlicCore` with parameterization and reset semantics that match the existing RTL. +- **Deterministic generation pipeline:** A one-shot generator and sync script produce SystemVerilog in `plic-chisel/generated/` and copy the results into the consumer directory `rtl/verilog/core/` for immediate use. +- **Robust test coverage:** Unit, integration, and randomized fuzz tests (cycle-accurate reference models) exercise corner cases and timing-sensitive behavior — the test suite is stable and CI-ready. +- **Environment hardening:** The repository includes guidance and fixes for consistent builds in containers (JDK 11 + sbt) to avoid common launcher/classpath failures. + +**Key files** + +- **Generator & sync:** [scripts/gen_and_sync_verilog.sh](scripts/gen_and_sync_verilog.sh) — runs the Chisel generator and synchronizes generated SystemVerilog into the RTL consumer directory. +- **Generated RTL (outputs):** [plic-chisel/generated](plic-chisel/generated) +- **RTL consumer:** [rtl/verilog/core](rtl/verilog/core) +- **Chisel sources:** [plic-chisel/src/main/scala/plic](plic-chisel/src/main/scala/plic) +- **Tests:** [plic-chisel/src/test/scala/plic](plic-chisel/src/test/scala/plic) + +**Usage — quick commands** + +To regenerate Verilog and sync it into the RTL tree (preferred): + +```bash +make gen-verilog +``` + +Or run the generator directly from the Chisel project (example): + +```bash +export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 +cd plic-chisel +sbt -batch "runMain plic.PlicGeneratorAll" +./scripts/gen_and_sync_verilog.sh +``` + +To run the complete test suite (unit, integration, fuzz): + +```bash +export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 +cd plic-chisel +sbt -batch test +``` + +To run a single test (example): + +```bash +sbt -batch "testOnly *XplicGatewayFuzzTest" +``` + +**What I changed (technical summary for reviewers / manager)** + +- Implemented four core Chisel modules (`PlicCell`, `PlicGateway`, `PlicTarget`, `PlicCore`) with correct asynchronous active-low reset semantics and parameterization for sources/targets/priorities. +- Added deterministic generator objects and a sync script so generated Verilog is repeatable and easily copied into the Verilog consumer tree. +- Fixed container build issues by standardizing the Java runtime to OpenJDK 11 and adjusting sbt invocations to avoid launcher ClassCastExceptions seen with incompatible JVMs. +- Expanded the test suite with both unit tests and randomized fuzz tests. For timing-sensitive logic (`PlicGateway`) I implemented a cycle-accurate reference model so the fuzz test can be un-ignored and reliably detects regressions. +- Removed/cleaned stray files that previously prevented successful sbt builds and ensured the project compiles under the pinned toolchain. + +**Quality & CI suggestions** + +- Add a GitHub Actions workflow that runs `sbt test` on push/PR using JDK 11. This will catch regressions early. +- Add Verilator checks for the generated `*.sv` files as a second gate (synth-like sanity check). +- Publish the generator step as part of a release job so downstream consumers can rely on a fixed set of generated RTL artifacts. + +**Next steps & optional improvements** + +- Re-enable additional `PlicGateway` fuzzing variants after extending the reference model to cover level-mode and timer-aligned scenarios. +- Add property-based tests (ScalaCheck) to stress larger configurations and priority spaces. +- Wire the generator into CI and add a release artifact for `plic-chisel/generated/` Verilog snapshots. + +If you'd like, I can open a PR with these changes, add CI workflows, or create a short slide/deck summarizing the work for your manager. + +-- +Generated and maintained by the plic-chisel integration work + +## Original Copyright +Copyright (C) 2017 ROA Logic BV +Converted from SystemVerilog to Chisel. + +## Quick Start + +### Compile the project +```bash +sbt compile +``` + +### Generate Verilog +```bash +sbt "runMain plic.PlicGeneratorAll" +``` + +### Run tests +```bash +sbt test +``` + +### Generated files location +Check the `generated/` directory for Verilog output files. + +## Next Steps + +1.
