Datasets:
Accessing MHRC-Bench resources
The code repository contains code. Dataset records, upstream repository snapshots and testbench assets are hosted separately here.
Standard task files
This repository contains a compact inspection sample: 256 training records per language, with the existing validation/test representations. The original sample_manifest.json records per-file counts; metadata_manifest.json verifies the current files. The compact VHDL test file has 513 rows while the classified test content has 496; do not align these by row index.
The full 44,964 / 453 / 1,783 task release is available at Zanehpn/MHRC-Bench. Use that release for full benchmark experiments. Eight small examples are available under samples/.
Repository sources
The existing source archive is pinned to Zanehpn/MHRC-Bench@cfea433c68462d01dd5c3fb88d4bbefd383bfb7d.

Extract into a directory of your choice. The archive's paths begin with
chisel/, systemverilog/, vhdl/, or hls/, followed by the source repository
name. For a task path repo/path/to/file, look under
<repository-root>/<language>/repo/path/to/file.
The archive is a legacy snapshot. Its individual Git revisions have not been rechecked against the current local-checkout inventory. The separate repository inventory provides upstream URLs and observed commits for direct source retrieval and provenance review.
Enriched context files
From the full release, for each language download valid_content_with_crossfile_context.jsonl or
test_content_with_crossfile_context.jsonl. Every row retains the corresponding
standard task fields. The crossfile_context string wraps other source files
with --- FILE: ... (BEGIN) --- / --- FILE: ... (END) --- markers. Target files
and whitespace-normalised exact copies are excluded. These resources are for
repository context; they do not change the number of validation or test tasks.
Functional testbench assets
Download functional_testbenches.tar.gz and extract it into a separate working directory. It includes source files, testbench code, build configuration, candidate mappings and the standard test records needed by the legacy runners. It excludes model predictions, result tables, compiler outputs and credentials.
This inventory does not establish successful behavioral execution:
| Language | Full test split | Candidate entries | Available DUT files | Entries with located testbench files |
|---|---|---|---|---|
| chisel | 323 | 70 | 23 | 13 |
| systemverilog | 508 | 50 | 50 | 50 |
| vhdl | 496 | 50 | 50 | 50 |
| hls | 456 | 50 | 50 | 37 |
Some candidates are missing source files or runnable harnesses. Read functional_coverage.json before selecting an evaluation subset. Report the actual coverage; do not infer a pass rate over all 1,783 tasks from this bundle. Elaborating or compiling alone is not a behavioral correctness test.
The legacy runners use g++ for HLS, VCS for the supplied SystemVerilog/VHDL
scripts, and sbt with Chisel/ChiselTest for Chisel. VCS and vendor libraries are
external licensed dependencies. These legacy commands are not interchangeable
with Icarus/GHDL without adapting their build scripts. The packaged Chisel build
specifies Scala 2.13.12, Chisel 6.0.0 and ChiselTest 6.0.0.
For example, from the extracted bundle root:
python hls_dataset/function_verify/run_function_verify.py /path/to/hls_predictions.jsonl --folders flat --output /path/to/hls_functional_results.jsonl
MHRC_REPO_ROOT=/path/to/original_repositories python vhdl_dataset/function_verify/run_function_verify.py /path/to/vhdl_predictions.jsonl --folders counter --output /path/to/vhdl_functional_results.jsonl
Legacy prediction files must follow the exact row order of the bundled
<language>_dataset/test_content.jsonl; each record supplies generated_code.
Use a fresh extracted working copy because the legacy runners patch local
files during execution. This release corrects the SystemVerilog helper to
compile the replaced DUT, removes attempts to alter system library symlinks,
and makes VHDL repository paths configurable with MHRC_REPO_ROOT.
Integrity and metadata
resource_manifest.json lists resource URLs, sizes and SHA-256 checksums. croissant.json describes the actual sample files in this repository. full-release-croissant.json is an unchanged copy of the full release Croissant/RAI file; use the full-release file when submitting the full benchmark to OpenReview. Public hosting does not confirm an OpenReview upload. Each JSONL representation is modeled separately; source and testbench archives are non-tabular resources. Third-party notices and unresolved root licenses are documented in LICENSE.md.
The mirrored repository inventory covers all 583 upstream repositories of the full release; it is a superset of those represented in this compact sample. Unresolved license cases and partial testbench coverage remain unresolved by mirroring.
