Files and directories

In a case of analog or mixed signal designs after successful cloning of the IHP-Open-DesignLib respository you should copy and rename the <design_name> directory in order to conserve the directory structure.

../
├── CODE_OF_CONDUCT.md
├── <design_name>
├── design_name
.
.   other designs
.
├── docs
├── LICENSE
├── pyproject.toml
└── README.md

The internal structure of the template named design_name is shown below:

../<design_name>/
├── design_data
├── doc
└── val

1. Use doc/ directory for respective documentation (md, rst) formats are recommended. It is recommended to document here the initial specification and the measurement results.

2. Use val to provide validation data like: test benches, raw simulaton results, sign-off reports, DRC and LVS reports. Try to keep the above mentioned data separated.

3. Use design_data to store your design related data like: schematic entries, gds files, netlists, configuration files, lef and liberty views. Try to keep the design data in a separate folders.

The design_data organization can be organized as follows:

../design_name
├── design_data
│   ├── gds
│   │   └── FMD_QNC_design_name.gds
│   ├── klayout
│   │   ├── design_name.gds
│   │   ├── drc
│   │   │   └── design_name.lyrdb
│   │   └── lvs
│   │       └── design_name.lyrdb
│   ├── README.md
│   └── xschem
│       ├── design_name.sch
│       ├── design_name_tb.sch
│       ├── simulations
│       │   ├── design_name.spice
│       │   └── design_name_tb.spice
│       └── xschemrc
├── doc
│   └── README.md
└── val
    └── README.md

It is mandatory to deliver the final gds in the gds directory with a prefix FMD_QNC

In a case of digital designs where OpenROAD-flow-scripts is used copy and paste the files from your local ORFS installation to the respective directories conserving the directory structures. An example of a riscv32i design is added in the repository in design_name directory (not all files are listed)

../design_name/
