Is there a Synthesizable syntax with writing file in verilog?? - Is there a Synthesizable syntax with writing file in verilog?? 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 Replies: Re: Is there a Synthesizable syntax with writing file in verilog??

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.
