**What is a Spice Symbol?** You first need to understand what a symbol is and then what the difference is between a Schematic Symbol and a Spice Symbol. This is explained here: [https://docs.easyeda.com/en/Simulation/Preliminary-remarks/index.html#How-to-find-Spice-Symbols-which-have-models-already-associated-with-them](https://docs.easyeda.com/en/Simulation/Preliminary-remarks/index.html#How-to-find-Spice-Symbols-which-have-models-already-associated-with-them)<br> <br> **What is a spice subckt?** You first need to understand what a Spice Model is and then what the difference is between a .model defined Spice model defined by a .model statement and a Spice model defined by a set of statements in a netlist called a subcircuit which then forma a .subckt defined model. This is explained here: [https://docs.easyeda.com/en/Simulation/Chapter14-Device-models/index.html#Device-models](https://docs.easyeda.com/en/Simulation/Chapter14-Device-models/index.html#Device-models)<br> <br> **What is the spice prefix?** You first need to understand what a Prefix is in an EasyEDA Schematic or PCB and then understand the difference between a Schematic or PCB Prefix and Spice Prefix. This is explained here: [https://docs.easyeda.com/en/Simulation/Chapter15-Schematic-symbols-prefixes-and-pin-numbers/index.html](https://docs.easyeda.com/en/Simulation/Chapter15-Schematic-symbols-prefixes-and-pin-numbers/index.html)<br> <br> I know it is a lot to read, understand and translate but it will help you a great deal if you read **How to design PCBs**, (2.2) and the **Spice Tutorial**, (3) in **Welcome to EasyEDA**, (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br> before you try to write a translation for EasyEDA into another language.
