所以我目前正在制作一个带有Altera Cyclone III板的单周期微处理器，我正在努力让我的时钟工作。时钟是一个按钮我按下我的电路板，以便将周期推进到下一个MIPS指令，并使用7-seg显示屏将其显示在我的电路板上。这是代码，请注意它很长：
module top(input logic clk, reset, switch, //top module that calls the others to form the processor
output logic [31:0] writedata, dataadr,
output logic memwrite,
output logic [6:0] HEX0, HEX1, HEX2, HEX3,
output logic LED1, LED2);
logic [31:0] pc, instr, readdata;
logic [31:0] rf [31:0];
logic rst, clock;
//logic reset;
// instantiate processor and memories
mips mips1(clk, reset, pc, instr, memwrite, dataadr, writedata, readdata);
imem imem1(pc[7:2], instr);
dmem dmem1(clk, memwrite, dataadr, writedata, readdata);
always
rst <= !reset;
//always
//clock <= !clk;
always
begin
LED1 <= clk;
LED2 <= switch; //at ALU out
if (switch)

我已分配引脚（BOARD IS EP3C16F484C6），但仍然没有任何反应。我想知道时钟是否进展顺利或重置按钮是否影响它。我只需要能够使用按下的按钮推进时钟周期并能够重置它。有任何想法吗？询问您是否需要更多代码，我很乐意提供。
