Hi

Can anyone please help me read decimal values from a text file using readmem.
I tried using $readmemh for hex values but it cannot read negative values. Can someone please help me read values (both positive and negative) in either hex or decimal format from text file?

Thanks in advance
 

$readmemh is not a very good function. Try using $fread instead. Works better, can read decimal or hex numbers and has a syntax similar to C programming.
