The calling code has direct knowledge of the function or task it’s invoking. How regular methods can be used like a callback ? Empty tasks can be positioned at key points within the code, allowing new code to be added to those spots later on. For example, pre_err_callback and post_...

I'm wondering if there is any ability to call a SystemVerilog/UVM Task/Function from Cocotb. Instead of living in purely Cocotb, or purely UVM, is it possible from the python side to direct and control the simulation? Say I start my test by calling a Cocotb async routine, then I want...
