Communication Between two FSMs in chisel

Interconnect from Scratch in Chisel

• In this project, we have Implemented the Topics coverd in the Chapter 4: Interconnects of the Book Fundamentals of System-on-Chip Design on Arm Cortex-M Microcontrollers by René Beuchat, Florian Depraz, Sahand Kashani, Andrea Guerrieri.
• Chapter 4 of this book covers, how interconnects can be made by scratch. These topics were Implemented in chisel in this project and verification testcases are written in Verilog.
