为了避免任何输出时钟的小故障,直到I1从高电平转换为低电平完成后,输出时钟转换并一直保持为低电平。 问题解决 在自己的设计中,有一个时钟I0是外部输入,另外一个I1为FPGA的PLL产生;若外部时钟不是一直存在,相当于I0为(H,L,X,Z某一状态),所以此时例化BUFGMUX的时候需要加上==异步==的属性: BUFGMUX#(.CLK...

Hello everyone. Mux verilog code below. They do the same, but option 2 got huge delays and cannot meet timing. Conclusion: they have different

2'b10 : q_o = c_i; default: q_o=d_i; endcase 既然心理想的是mux,用case來窮舉自然最一目暸然, 根據[3]Altera所推薦coding style,當使用case時,Quartus II會使用parallel mux來實現。 Testbench mux_case_tb.v / Verilog 1/* 2(C) OOMusou 2010http://oomusou.cnblogs.com ...
verilog mux在时钟边缘 如何使用时钟边沿作为多路复用器的选择器,我想做什么: input clk, in1, in2; output out; always@ (posedge clk) begin out<=in1; end always@(negedge clk) begin out<=in2; end Run Code Online (Sandbox Code Playgroud) 但是,这是不可合成的,因为在单独的always块中有多...

高质量VerilogHDL描述方法 晚的话,那么第二种电路的性能就会比第一种差。 综上所述,在设计的时候要根据输入约束,再来选择两种不同的设计:是先加后选,还是先选后加。2、 If的优先级问题 多if语句具有优先级的判断结构,即输入...)。 我们来看看上面的第一段代码,我们心中要出现该代码描述的电路,该电路由两个...
