1.系統功能塊

• 本地檔案讀入，後兩項可預設

$readmemb ("<資料檔名>",<存貯器名>,<起始地址>,<結束地址>)
$readmemh ("<資料檔名>",<存貯器名>,<起始地址>,<結束地址>)

reg [379:0] CAL2_sample[0:2999];
initial $readmemb ( "./../matlab/ideal_high_freq_sample_bits.txt", CAL2_sample,0,2999 );

tdc_finecode_i <= CAL2_sample[samlpe_cnt];

• 將列印結果儲存至文件

// finetime_o finetime_valid_o 為dut輸出
integer fid;
initial
	fid = $fopen("fintimeout_ideal1.txt","w");
	
integer finetime_cnt=0;
always@(posedge main_pll_clk_80m_i or negedge rst_n) begin
	if(!rst_n) begin
		finetime_cnt <= 'd0;
	end
	else if(finetime_cnt==2999) 
		$fclose(fid); 
	else if(finetime_valid_buf==2'b01) begin
		finetime_cnt <= finetime_cnt + 1'b1; 
		$fwrite(fid,"%d\n",finetime_o); 
		$display("%d",finetime_o);
	end 
	finetime_valid_buf <= {finetime_valid_buf[0],finetime_valid_o};
end
