从循环产生激励有以下特性: 在每一次循环,修改同一组激励变量 时序关系规则 代码紧凑 module loop_tb; reg clk; reg [7:0] stimulus; wire [7:0] results; integer i; DUT u1 (results, stimulus); always begin // clock generation clk = 1; #5 clk = 0; #5 end initial begin for (i = 0...
Synchronous logic blocks are generated using special identifiers in the sensitivity list. Here we only want to update on the positive edge of the clock, so we use posedge. This will generate a synchronous circuit that implements x every clock cycle. inputclk;reg[1:0] x;always@(posedgeclk)be...

It clears the flip-flop’s memory precisely when the clock ticks. Here’s a Verilog code for a D Flip-Flop with synchronous reset: module dff_sync_reset( input wire clk, reset, input wire d, output reg q ); always @(posedge clk or posedge reset) if (reset) q <= 1'b0; // ...

why it generates verilog in the code: "module hls_aes256_internal ( input logic clock, input logic resetn, input logic clock2x, output logic done_irq, // AVS avs_control input logic avs_control_enable, input logic avs_control_read, input logic avs_control_write, input logic ...
The library is written in standard Verilog (2005) and contains over 25,000 lines of Verilog code, over 150 separate modules. Examples of functionality include: FIFOs, SPI (master/slave), GPIO, high speed links, memories, clock circuits, synchronization primitives,interrupt controller, DMA. ...
This confuses the synthesis tool (Vivado to be precise) and throws an error saying there is an ambiguous clock event. Removing the "or posedge reset" part solves this issue. This one might also be a problem with Vivado. The Verilog code generated for the Counter code attached (just counts...
