$readmemb

Hi vivek_p ,
What do you want to do ? Do you want to create a ROM at synthesis time ? Did you consider `DEFINE ?
 

Re: $readmemb

How can I synthesise memory using 'define.............can you please explain

Added after 6 minutes:

Can you please explain will the below code be synthesized to a 8 byte memory..................Is there any other efficient way to synthesize memory


module..........
....................

reg [7:0] data;

always @(posedge clk)
begin
if(rst)
begin
data <=8'b0;
end

else
begin
case(addr)
10'd0: data <=8'd2;
10'd1: data <=8'd7;
.
.
.
10'd9 : data <=8'd10;
endcase
end
end


Can you please help?????
 

$readmemb

I think the piece of code you mentioned is already synthesizable

Re: $readmemb

Your code is convenient for small lookup table. But for large one, compiled ROM is smaller in size.
