This dataset is released under the Apache License, Version 2.0 (see LICENSE).
================================================================================
This dataset contains Derivative Works of three upstream corpora. Their
original licences are reproduced verbatim in the LICENSES/ directory and MUST
be included in any downstream redistribution of this dataset.
================================================================================
1. Open Circuit Benchmark (OCB) — Ckt-Bench-101 + Ckt-Bench-301
Upstream: https://github.com/zehao-dong/CktGNN
Paper: Z. Dong, W. Cao, M. Zhang, D. Tao, Y. Chen, X. Zhang.
"CktGNN: Circuit Graph Neural Network for Electronic Design
Automation." ICLR 2023.
Licence: MIT (see LICENSES/LICENSE-OCB)
Use in this dataset:
The 60,000 rows where `source_dataset == "ocb"` are derived from OCB's
behavioural opamp graphs. Each graph was remapped from its upstream
(gm, R, C) sub-circuit representation to a transistor-level SKY130
netlist via an equivalent-subcircuit library, then simulated in ngspice.
Circuit IDs preserve the upstream sub-benchmark partition:
ocb_sky130_101_* — 10,000 graphs (Ckt-Bench-101, diversity sample)
ocb_sky130_301_* — 50,000 graphs (Ckt-Bench-301, BO-curated)
2. AnalogToBi
Upstream: https://github.com/Seungmin0825/AnalogToBi
Paper: Seungmin Lee et al. "AnalogToBi: Device-Level Analog Circuit
Topology Generation via Bipartite Graph and Grammar-Guided
Decoding."
Licence: MIT (declared in upstream README; see LICENSES/LICENSE-AnalogToBi
for the note on the missing upstream LICENSE file and the
reproduced standard MIT text)
Use in this dataset:
The 67,736 converged + 2,177 failed rows where
`source_dataset == "analogtobi"` are derived from AnalogToBi's 3,350
textbook + paper analog-circuit topologies. This includes a 1× default-
sizing baseline and a 20-point Latin-Hypercube sweep over W, L, Ibias,
and CL applied by our simulation pipeline before ngspice runs. Upstream
netlists ship in Cadence Spectre dialect; our pipeline converted them
to ngspice dialect.
3. AnalogGym
Upstream: https://github.com/CODA-Team/AnalogGym
Paper: CODA-Team. "AnalogGym: An Open and Practical Testing Suite for
Analog Circuit Synthesis." ICCAD 2024.
doi:10.1145/3676536.3697117
Licence: BSD 3-Clause (see LICENSES/LICENSE-AnalogGym)
Use in this dataset:
The 500 rows where `source_dataset == "analoggym"` are derived from
AnalogGym's 22 ngspice-ready SKY130 topologies (16 amplifiers + 1 LDO
+ 4 voltage references + 1 charge pump), each expanded by a 20-point
LHS sweep. The charge-pump sub-circuit is a structural homage of the
SMIC 130 nm PLL charge pump from the AnalogGym repo — model-name
tokens were remapped to SKY130 equivalents and layout-dependent
parameters were stripped.
Per the BSD 3-Clause no-endorsement clause: neither the names of
AnalogGym, CODA-Team, nor any of their contributors may be used to
endorse or promote products derived from this dataset without specific
prior written permission.
Third-party tools and data referenced but NOT redistributed
================================================================================
- SkyWater SKY130 PDK (Apache 2.0) — https://github.com/google/skywater-pdk.
The shipped netlists reference SKY130 `.lib` and `.model` names (e.g.
`sky130_fd_pr__nfet_01v8`) but do not embed any PDK model files.
Users wishing to re-simulate must install the PDK themselves (e.g.
via https://github.com/efabless/volare).
- ngspice — http://ngspice.sourceforge.net/. The simulator used to
produce every row's metrics. Not redistributed.
