看别人的吧:Verilog code for D flip-flop - All modeling styles (technobyte.org)Verilog: T flip flop using dataflow model - Stack Overflow 我倾向于认为Verilog的<=没那么强; 它可以偷偷地把 q <= ~((enable & reset) | q_); 换成if嘛。 1. 叫modeling style不叫coding style. 2. if (!con...

The following code describes a flip-flop with input d and output q, clocked by positive edge of clk (with no reset): always @(posedge clk) q <= d; Let’s make it a more complete flip-flop design by also adding a reset, namely an asynchronous reset. An asynchronous reset means the...
