+# ChiPBench-D
+
+This project represents the dataset part of ChiPBench. The code can be found on GitHub: [ChiPBench](https://github.com/MIRALab-USTC/ChiPBench).
+
+## Details
+
+The file structure of the dataset is as follows:
+
+```bash
+ChiPBench-D
+├── data
+├── kits
+├── raw_data
+├── ForMacroPlace
+├── getdata.py
+├── utils.py
+```
+
+- **data**: Contains original RTL, netlist, DEF, and SDC files, along with specific LEF and LIB files for each case.
+- **kits**: Contains global LEF and LIB files.
+- **raw_data**: Includes all the original files used by OpenROAD. If you only need to evaluate placement algorithms, you can skip downloading this folder.
+- **ForMacroPlace**: Contains DEF files for Macro Placement. If you only need to perform macro placement, you can download this folder only.
+- **getdata.py**: Custom script for organizing data.
+- **utils.py**: Dependencies for the `getdata.py` script.
+
+### data
+
+```bash
+data/Nangate45
+├── case_name
+│   ├── def
+│   ├── lef
+│   ├── lib
+│   ├── rtl
+│   ├── 1_synth.v
+│   ├── config.mk
+│   ├── constraint.sdc
+```
+
+- **def**: DEF files related to various stages of EDA.
+- **lef**: Case-specific LEF files.
+- **lib**: Case-specific LIB files.
+- **rtl**: Original RTL files for the case.
+- **1_synth.v**: Synthesized netlist files for the case.
+- **config.mk**: Configuration files for running in OpenROAD-flow-scripts.
+- **constraint.sdc**: Timing constraint files for the case.
+
+### kits
+```bash
+kits/Nangate45
+├── lef
+├── lib
+```
+
+- **lef**: Contains global LEF files.
+    - `Nangate.lef`: A combined LEF file from NangateOpenCellLibrary.macro.mod.lef and NangateOpenCellLibrary.tech.lef.
+- **lib**: Contains global LIB files.
+
+### raw_data
+Contains all original files, available for download as needed.
+
+### getdata.py & utils.py
+
+Custom scripts for organizing data.
+
+Parameters:
+```
+--formacroplace: Copies all macro placement DEF files for each case to the ForMacroPlace directory.
+--forcellplace: Copies DEF files for cell placement cases (without macros) to the ForCellPlace directory.
+--forallcellplace: Copies all DEF files for cell placement cases to the ForAllCellPlace directory.
+--afterstage: Copies files from all cases after the specified stage (place, route, cts) to the corresponding directory.
+--getnetlist: Copies netlist files from all cases to the netlist directory.
+```
+
+Example:
+```
+python getdata.py --formacroplace
+```
+The `ForMacroPlace` directory will contain the corresponding DEF files.
+
+```
+python getdata.py --afterstage="cts"
+```
+The `after_cts` directory will contain the corresponding DEF files.
+
+### ForMacroPlace
+
+To facilitate usage, the `ForMacroPlace` directory generated by the above script has been uploaded.
+
