Web这个模型在posedge clk之后或在negedge rst_n之后让输出延迟1时间单位（1ns）。这个延迟有效地实现了1ns的clk-to-q 或者rst-to-q 的延迟，查看波形时更容易理解，因为这个延迟让我们更容易理解波形。 WebMar 13, 2024 · 电路模块的输入信号有时钟信号clk，低有效的复位信号rstb，控制模块开始工作的信号ctrl_start，128位的数据总线data_in； 电路模块的输出信号有串行输出时钟信号out_clk，串行输出数据信号out_data，串行数据加载信号out_load； 电路模块的功能描述：ctrl_start为高后的第一个clk上升沿驱动模块开始工作 ...

多种时序逻辑always语句的综合结果与分析 - 知乎

WebAug 31, 2024 · In general posedge clk is used, to trigger a flop at positive edge of clock. Most of the reads and writes or state changes takes place at posedge. negedge clk is used to similarly trigger at negative edge.This is used less frequently unless using for DDR2/3 etc. If you are writing on a posedge, reading would be useful on a negedge. WebApr 24, 2024 · I want to build a Verilog module so that the user can select the sensitivity of some input clock signal by a module parameter. As an example, I wrote the following counter which can either count up on posedge or negedge selected by parameter clockEdge.. module Counter (clk, reset, value); parameter clockEdge = 1; // react to … tick in my bed
