Solved: i know high level async reset can be achieved like: always@(posedge clk or posedge rst) begin if (rst==1) but how to realize posedge async

For example, the logic that creates the FPGA's reset signals immediately after the FPGA wakes up. An example of such logic is shown on the third page of this series. With most synthesizers, setting a register's initial value is quite simple: Use Verilog's "initial": reg [15:0] ...
A set_false_path on those paths seems a little careless in my opinion. I'm quoting the Verilog code and the constraints given as example in the handbook: module sync_async_reset ( input clock, input reset_n, input data_a, input data_b, output out_a, output out_b ); reg reg1...
The synchronization of an asynchronous reset is shown in the following figure for CLEAR-based synchronization, and in the subsequent figure for PRESET-based synchronization. The FF1 cell is respectively connected to the synchronized clear or preset signa
In the Verilog code of Example 1a and the VHDL code of Example 1b, a flip-flop is used to capture data and then its output is passed through a follower flip-flop. The first stage of this design is reset with a synchronous reset. The second stage is a follower flip-flop and is not...
