Is there a Synthesizable syntax with writing file in verilog??

[euem789]

Hi guys,

Now I'm Using

--------------------------

Software : Quartus 18.1

Board : DE1 - Soc

-------------------------

I'm facing problem with FILE IO in verilog . (

what I want to do is making an output file with synthesizable syntax (targeting the implementation of FPGA board Not for simulation)

here's the code I wrote.

module readmem(clk);
	input clk;
	
	reg [7:0] rmem [0:2];
	reg [7:0] wmem [0:2];
	
	initial begin
		$readmemb("C:\\test_num.bin",mem);
		$writememb("C:\\test_num_reslut.bin",wmem);
		
		wmem[0]=(rmem[0]<<1);
		wmem[1]=(rmem[1]<<1);
		wmem[2]=(rmem[2]<<1);			
	end
endmodule

After compile what I expected  was generated  output file 'test_num_result.bin'  but nothing happend.

I heard that $readmem syntax is able to synthesize( also used for memory initialization),  and there was no problem with compilation.

and no error with $writemem syntax too.

Could someone tell me am I doing right??

I'll be really appreciated if someone tell me what's wrong....

and furthermore,

- Is it possible to perform only with verilog in quartus??

  or do I have to use a soft processor (NIOS) ??

( What I'm trying to do for my project is reading a image file with applying sobel-mask and then, making an output file through my FPGA board)

thanks for reading

Hi,

According to https://www.intel.com/content/www/us/en/programmable/quartushelp/current/index.htm#hdl/vlog/vlog_list_support_d1625e1153.htm, only $readmemb/$readmemh are supported.

Thanks
