    verilog Difference between Synchronous and Asynchronous reset in Flip Flops Stack Overflow

    Synchronous reset requires more gates to implement (see the example below). The latter example is typically implemented as follows always @(posedge clk or posedge reset) begin if(reset == 1'b1) reg <= 0; //reset. They are synchronous and asynchronous resets.

    In the above example, you can see that out1 will be changed only with the posedge of clk.
    Reset line is sensitive to glitches. Will meet reset recovery time, as the deassertion will happen within 1 clock cycle. It is slow.

    This is because State Variables are physically implemented with the help of Flip-Flops, and each Flip-Flop can only represent 2 possible states.

    In the asynchronous reset code why are we using the always posedge clk or posedge reset instead of using always posedge clk. Question feed.

    Whether to use synchronous or asynchronous resets in a design has almost become a In the Verilog code of Example 1a and the VHDL code of Example 1b.

    Reset may be either synchronous or asynchronous relative to the clock One example is a synchronous design that gets no active clock at.

    An asynchronous reset implies that you have a FF in your library that actually has a async clear (or async set) input. These tend to be a little.
    Reset gets the highest priority. Doov Doov 4 4 silver badges 14 14 bronze badges.

    I read about asynchronous and synchronous reset and i think i got hold of it but while implementing the same with verilog i am not able to understand a line of code which i saw on this website. Abhishek Tyagi Abhishek Tyagi 1 1 gold badge 2 2 silver badges 15 15 bronze badges.

    Synchronous design with Verilog

    That means, reset forces the design to a known state. Will meet reset recovery time, as the deassertion will happen within 1 clock cycle. In a Synchronous Sequential Circuit all the State Variables representing the internal state of the circuit change their state simulteneously with a given input clock signal to achieve the next state.

    The key word is "or".
