Asynchronous flip-flop 专利名称：Asynchronous flip-flop 发明人：Beltramini, Angelo 申请号：EP88304427.3 申请日：19880516 公开号：EP0291360A2 公开日：19881117 专利内容由知识产权出版社提供 摘要：An asynchronous flip-flop comprises an RS flip-flop output circuit with set and reset inputs connected to...
在这个always block中q1后面跟着一个无reset的q2,复位信号rst_n变成q2的数据使能信号,产生额外的逻辑。 正确的方式构建follower flip-flop是用两个verilog程序块。 1 2 3 4 5 6 7 8 9 10 11 module goodFFstyle(q2,d,clk,rst_n); output q2; input d,clk,rst_n; reg q2,q1; always @(posedge clk...
PROBLEM TO BE SOLVED: To provide a flip-flop with asynchronous set/reset using the flip-flop with the asynchronous set and the flip-flop with the asynchronous reset. ;SOLUTION: This circuit is provided with the flip-flop circuit 3 with the asynchronous set, the flip-flop circuit 1 with the...
“1”) connected to the D port of flip-flop F0 is synchronized. F0 may become metastable, however, since the input of F1 does not change on the first clock edge, F1 is not subject for a metastability. Thus, the constant “1” input is synchronized using a two-flip-flop synchronizer,...

同步复位的前提是,复位信号只会在时钟的有效边沿去影响或者复位flip-flop。Reset可以作为组合逻辑的一部分送给FF的D端。这种情况下,编码方式必须是if/else 优先级的方式,而且reset只能放在if条件下,其他组合逻辑放到else逻辑下。 正确的方式去构建同步复位FF的verilog代码如下: ...
Since the D-Type Flip-Flop 13 has been cleared by the reset pulse the Q output pin will be a logic one and is connected to input pin of NAND gate 14. The result of these two high inputs that appear on NAND gate 14 will cause its output pin to be a logic zero. The output pin...
Infineon's Asynchronous SRAMs offer High speed, Low power with on-chip ECC to suit a variety of applications Async SRAM is a type of Volatile random-access memory (RAM) that uses flip-flop based latching circuitry to store each bit. The data bits are retained in memory as long as power...
