What is Cocotb?

Cocotb is a Python-based framework for verifying digital circuits. It acts as a cosimulation layer enabling you to write testbenches in Python to drive and monitor hardware description languages (HDLs) such as VHDL and Verilog/SystemVerilog simulations. Cocotb is commonly used to automate testing, perform regression testing, and implement complex verification scenarios for digital designs. It provides an abstraction layer that simplifies interaction with the simulator and allows for more readable and maintainable testbenches compared to traditional HDL-based verification.
