 - Considering ZigZag-IMC framework is an enhanced version of ZigZag framework, we have merged this ZigZag-IMC repository with the [ZigZag framework](https://github.com/KULeuven-MICAS/zigzag) for an easy maintenance. 
 Please refer to the [ZigZag framework](https://github.com/KULeuven-MICAS/zigzag), which will have regular updates and maintenance, if you are looking for ZigZag-IMC framework. This repository for ZigZag-IMC will no longer be maintained in the future.
