I need some more clarification regarding GDSII files. the following are the questions which i have in my mind
1.Can we create our own libraries and adding them to another technology files?
2. Suppose I have free pdk files with me, can we add more(created by me ) components into that library files?
3. If I create my own files(.lib,.lef ) files which software do I require to test it?
4.If I generate GDSII file using my own library files,can I give to any foundry or can this file will be accepted by any foundry?
