IPM

IPM is an open-source IPs Package Manager; it is meant to provide a mean for distributing high quality open-source IPs.

Installation

1. Clone the IPM GH repository

pip install ipmgr

2. To verify it is working run:

ipm --version

Note: Before installing IPM you must uninstall previous version of IPM using the following commands.

pip uninstall ipm
pip uninstall ipmgr

Usage

Listing all Verified IPs

ipm ls-remote

Lists all verified IPs supported by IPM, and verified by efabless, it shows the primary details about the IPs.

Getting more info about an IP

ipm info <ip_name>

Gives more details about a specific IP.

Listing Installed IPs

ipm ls

Lists all locally installed IPs on the machine.

Installing an IP

ipm install <ip_name> [OPTIONS]

Installs the IP by default in {PWD}/ip, you can also specify the ip installation directory using --ip-root. The user must provide a valid ip_name, to check all available IPs run ipm ls-remote. To install a specific version of the IP you can specify it using --version <version> While IPM is installing the IP, if the IP's bus is generic it will create bus wrappers for AHBL, APB, WB and will create firmware fw, using bus wrapper generator tool

Installing IPs from dependencies file

ipm install-dep <ip_name> [OPTIONS]

Installs IPs specified in a dependencies file, by default it looks in {PWD}/ip/dependencies.json. You can specify the dependencies file location using --ip-root

Uninstalling an IP

ipm uninstall <ip_name>

Uninstalls a locally installed IP. The user must provide a valid installed ip_name, to check all installed IPs run ipm ls. It is advised to always use this function when you wish to remove an IP. If you deleted the folder manually or renamed it this function may face errors

Remove IP from project

ipm rm <ip_name>

Removes the IP from the project, but doesn't uninstall it from the machine, to uninstall from machine use ipm uninstall, it is advised to rm from project before uninstalling.

Checking for Updates

ipm check [OPTIONS]

Checks if there are newer versions available for the installed IPs. The function by default checks all the installed IPs for updates.

Updating Installed IP

ipm update [OPTIONS]

Updates the IP if an update is available.

Adding your IP to IPM

To add your own IP to our package manager, you should follow these steps:

1. Package your IP with the following folder structure:

All IPs must include:

- readme.md
- <ip>.json
- doc/datasheet.pdf
- hdl/rtl/bus_wrapper **optional**
- fw
- verify/beh_model

All digital and analog hard IPs must include:

- hdl/gl
- timing/lib
- timing/sdf
- timing/spef
- layout/gds
- layout/lef

All Analog IPs must include:

- spice

All soft digital IPs must include:

- hdl/rtl/design
- verify
- pnr **optional**
- verify/utb

Directory structure should look like:

├── readme.md
├── <ip>.json
├── doc\
│   └── datasheet.pdf
├── layout\
│   ├── gds\
│   └── lef\
├── timing\
│   ├── lib\
│   ├── spef\
│   └── sdf\
├── spice\
├── hdl\ 
│   ├── rtl\
│   │   ├── bus_wrapper\
│   │   └── design\
│   └── gl\
├── fw\
├── verify\
│   ├── utb\
│   └── beh_model\
└── pnr\

NOTE

• verify directory should include basic unit tests to help the designers build their verification
• bus_wrapper directory contains RTL for IP wrappers to ease system bus connection
• fw directory contains device drivers (.c and .h files)

2. IP metadata file structure

Your <ip>.json file should look like:

{
    "info": {
        "name": "<ip name>",
        "description": "<ip_description>",
        "repo": "<src repo>",
        "owner": "<owner of IP>",
        "license": "<license of IP>",
        "author": "<author of IP>",
        "email": "<email of author/owner>",
        "version": "<IP version>",
        "date": "<mm-dd-yyyy>",
        "category": "<analog/digital/AMS>",
        "tags": [
            "<tags for ip>"
        ],
        "bus": [
            "<APB|AHBL|WB|generic>"
        ],
        "type": "<hard|soft|firm|hybrid",
        "status": "<Verified|FPGA Validated|SI Validated|Production Ready>",
        "cell_count": "<number of cells in ip>",
        "width": "<width of IP in um>",
        "height": "<height of IP in um>",
        "technology": "<sky130A|sky130B|gf180mcuC|gf180mcuD|n/a>",
        "clock_freq_mhz": "<clock frequency of IP>",
        "supply_voltage": [
            "<supply voltage of IP>"
        ]
    }
}

All the above fields must be included in your file

3. Create tarball

Compress your folder into a tarball (tar.gz) with the name <version>.tar.gz, where version is the version of your release, you can do that by running:

cd <ip_directory>
tar czf <version>.tar.gz *

4. Create release

create a new release in your GH repo with the tag <version> and add the tarball created there to the release's assets

5. IPM package_check

Once you are done you can run a package_check function locally by running ipm package-check which checks that you’ve completed the above steps successfully. Options for IP name, version and the GH repo are required

NOTE: THIS IS STILL A WIP

6. Submit

If the pre-check was successful you can submit your IP through the form ......

IPM team will then perform set of sanity checks to ensure the quality of the submitted IP. This checker shall ensure:

• That the IP is LVS clean
• That the IP is DRC clean
