Consider reducing the collapsing input limit or the product term limit to prevent the fitter from creating high input and/or high product term functions.整个程序太长这里只是部分我认为和赋值相关的代码module wash(clk1k,d0,d1,reset,t1l,t1h,t2l,t2h);input clk1k,reset;input d0,d1;output t1l,t1h,t2l,t2h;wire forward_wire,back_wire,stop_wire,sound_dc_wire;wire start;reg [3:0]t1l,t1h,t2l,t2h;wire [3:0]d0,d1;always (posedge clk1k)if (reset)begin{t1l,t1h,t2l,t2h} 16d0;endelsebeginif({d0,d1}!8h0)begint1hd0;t1ld1;end谢谢各位了我还是个新手这个问题困扰我好几天了展开
