# ChiPBench-D

This project represents the dataset part of ChiPBench. The code can be found on GitHub: [ChiPBench](https://github.com/ZhaojieTu/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.
