# Frontend - backend GDS bridge

|
Each canvas in the fronend should create a same name **.yaml** file.
|
|
This **.yaml** should contain the following parts.
|
|
|
|
- basic description : name, type, version
|
|
- ports : the output connection ports for this canvas object
|
|
- instances : the instance objects from **PDK** or other **canvas**, together with their **x, y, a, mirror** informations.
|
|
- bundles : 1-1 or N-N conenctions that used for auto routing. "***This***" refers to the canvas ports.
|
|
|
|
