Before designing chip by iEDA，you need to obtain the execution binary of iEDA.
If you need to modify iEDA through source code construction, please read in sequence.
You can also directly use the latest release docker， then you can skip "1. Source code construction of iEDA".
PS: you can refer Docker install and initilization to know how to install Docker.
We provide two methods for source code construction of iEDA as examples.
Download the latest “iedaopensource/base” mirror from Dockerhub, which includes the latest master branch code and dependencies (build tools and dependency libraries). You can also use the ‘-v’ command to mount your own downloaded iEDA code repository. The build will only use the compile tools and dependency libraries provided by the mirror.
The current directory after entering the container is the iEDA master branch code, refering the following commands:
# ieda opensource/base:(latest, ubuntu, debian)
docker run -it --rm iedaopensource/base:latest bash
# enter docker and run build.sh to build
bash build.sh
# if output "Hello iEDA!", then compile successfully
./bin/iEDA -script scripts/hello.tcl
We have ubuntu（Ubuntu20.04）and debian（Debian11）mirror tag.
installing command on Ubuntu 20.04:
# download iEDA repo
git clone --recursive https://gitee.com/oscc-project/iEDA.git iEDA && cd iEDA
# compile dependencies with an apt installation requires root permission
sudo bash build.sh -i apt
# comple iEDA
bash build.sh
# if output "Hello iEDA!", then compile successfully
./bin/iEDA -script scripts/hello.tcl
Here, two iEDA operation methods are provided for reference
About how to use iEDA, please refer Tcl command manual and the tool instruction docs of readme.md in src/operation.
If you need to use custom processes and designs, mount the associated files into the docker to run. About the structure and the corresponding config files, please refer the demo in scripts/sky130.
docker run -it -v ${file directory of pdk and design}:${file directory in docker} --rm iedaopensource/release:latest
Refering the file directory in scripts/sky130，add the path of iEDA execution binary into the system path variable $PATH, and runing sh run_iEDA.sh，and seeing the result in result.
