| This sample PCell implements a library called "MyLib" with a single PCell that |
| draws a nmos5d10_gen. It demonstrates the basic implementation techniques for a PCell |
| and how to use the "guiding shape" feature to implement a handle for the nmos5d10_gen |
| radius. |
| |
| NOTE: after changing the code, the macro needs to be rerun to install the new |
| implementation. The macro is also set to "auto run" to install the PCell |
| when KLayout is run. |
