WebbGenerate blocks are evaluated during elaboration time and the result is determined before the simulation begins. In other words generate statements are NOT a run-time construct. If you think about it for a second, the generate construct is actually creating a circuit and we cannot add or remove hardware circuits on-the-fly, so it does make sense that a … WebbA SystemVerilog implementation of a Ethernet Repeater targeting a Terasic DE2-115 and Marvell 88E1111 PHY ...
