Build a 2-to-1 mux that chooses between a and b. Choose b ifbothsel_b1 and sel_b2 are true. Otherwise, choose a. Do the same twice, once using assign statements and once using a procedural if statement. 构建一个在a和b之间进行选择的2对1 mux。如果sel_b1和sel_b2都为true,则选择b。

low, that set is still high. In a real flip flop this will cause the output to go to a 1. However, in this model it will not occur because the always block is triggered by rising edges of set and reset - not levels. A different approach may be necessary for set/reset flip flops...
