![]() ![]() ![]() The simulation stop command is issued by a $finish task deep in the UVM base-classes.This cannot be specified within the SystemVerilog/HDL code, and therefore need to come from the Python world Constrained-randomization based testbenches require a seed value to be passed from the simulation command-line at run-time.Testcases/testsuites are not declared within the top-module in the SystemVerilog world. The argument for this function is specified at run-time using the simulator argument +UVM_TESTNAME=. The toplevel module which is passed to the simulator command calls a run_test (from the UVM base), which dynamically creates the class-based testbench hierarchy.Nevertheless, it would be nice to add the support for this style either using SystemVerilog or Python-based adaptations. UVM testbenches have a top-level SystemVerilog module which has a slightly different style than a Vunit-based SystemVerilog testbench. ![]() UVM testbenches are widely used for verification, and Vunit could be used as a flow-controller for such methodologies, if some adaptations are made. ![]()
