Fix undefined clk_div in freq_meter.sv

[JacyCui]

Description

This pull request addresses the issue of the undefined clk_div signal in the freq_meter.sv file. The clk_divider module is now instantiated to generate the clk_div signal, ensuring proper functionality of the freq_meter module.

Changes Made

Modified the instantiation of the clk_divider module to define and generate the clk_div signal.

Modified File

logic [31:0] clk_div;

clk_divider #(
  .WIDTH(32)
) sys_cd (
  .clk(clk),
  .nrst(nrst),
  .ena(1'b1),
  .out(clk_div)  // Connected clk_div to the clk_divider output
);

Testing

• Verified that the freq_meter module synthesizes without errors.
• Confirmed that the clk_div signal is properly generated and used in the module.
