| Open-PDKs (open_pdks) |
| ----------------------------------------- |
| |
| Summary: |
| |
| Automatic setup of PDKs for open-source tools from foundry sources. |
| |
| Builds out and populates a new set of directories and subdirectories in |
| the efabless format, with the efabless name for the PDK at the top, |
| followed by categories "libs.ref" (IP) and "libs.tech" (EDA tool setup), |
| each with subcategories corresponding to layout, abstract views, |
| netlists, etc. for the IP; and magic, netgen, qflow, etc., for the |
| EDA tool setup. |
| |
| The populated PDK directories can contain either copies of files from |
| the foundry sources, links to the foundry sources, or links back to |
| another PDK. |
| |
| Generates magic layout views for all vendor IP for which either a GDS |
| view or a LEF view exists. Annotates the views as needed to handle |
| ports, bounding boxes, etc. |
| |
| ----------------------------------------- |
| |
| This distribution contains sources for building out the SkyWater SKY130 |
| 130nm process. Sources for the foundry process data must be obtained |
| separately. Read the README file in subdirectory sky130/ for instructions |
| on obtaining and building the SkyWater sky130A PDK. |

| Instructions: |
| |
| git clone https://github.com/RTimothyEdwards/open_pdks.git |
| cd open_pdks |
| ./configure [options] |
| make |
| [sudo] make install |
| |
| where the configure [options] are specific to each foundry PDK supported |
| by open_pdks and can be queried using |
| |
| ./configure --help |
| |
| At a minimum you will want to pass a configure option to declare the PDK |
| that you want to build. It is possible to build multiple PDKs at once, |
| but not recommended due to the large memory and disk space overhead |
| required by each one. |
| |
| ./configure --enable-[PDK_name]-pdk |
| |
| The open_pdks version of the PDK can be built locally within open_pdks without |
| the need to declare an install target or run "make install". However, it is |
| highly recommended to declare a target location and install there, using |
| |
| ./configure --prefix=[path] --enable-[PDK_name]-pdk |
| |
| followed by "make" and "make install". The default install location is |
| /usr/local/share/pdk ([path] above is /usr/local). The install location |
| should be a read-only filesystem area for regular users, since the PDK |
| contents should not be altered. |
| |
| Also see the website at http://opencircuitdesign.com/open_pdks/. The "Install" |
| page has full instructions for configuring and installing open_pdks. |
