WebApr 6, 2024 · Assigning the initial value to h01 will solve the problem. alp h1 = h01; Output: h01 1 h02 2 h03 3. My understanding here is : The default init value in systemverilog is 0, and as 0 points to nothing/null in your enum; the display is 0. For the same reason the next operator doesn't make sense either and it's stuck at 0. WebSystemVerilog consigns the confusion to history: variables may be assigned using procedural assignments, continuous assignments and being connected to the outputs of module instances. Unfortunately, you still can't connect variables to inout ports, although you can pass them using ref ports. push in python list
