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...
A reference is only valid during an active call of that task/function. A block with a static lifetime means that the variables inside the block, as well as arguments to tasks and functions, are all allocated and initialized at time 0 (Verilog is designed for hardware…). Example of ...

How does SystemVerilog know which new function to call? It looks at the type of the handle on the left side of the assignment. 1,顶层的虚拟接口传递给program,然后再通过class的new函数传给class,然后开始对接口做一些动作。 2,A scope is a block of code such as a module, program, task, fun...
