From: "HDL basic training: top-down chip design using Verilog and VHDL" Douglas J Smith, VeriBest 1996 (big article) . . . Ease of learning. If you have no knowledge of either language, Verilog is probably easier to grasp and understand. This statement assumes the exclusion of the Verilog compiler directive language for simulation and of the PLI. If you include these two, consider them additional languages you need to learn. Also, VHDL may seem less intuitive at first for two reasons. First, it is very strongly typed, a feature that makes it robust and powerful for an advanced user after a longer learning phase. Second, there are many ways to model the same circuit, especially one with large hierarchical structures. . . .
