When i tried to simulate my code(vhdl) , it says Isim doesn't support traceable variables and shows an error at 0 ps: Error: :fixed_pkg:READ(sfixed) Decimal point does not match number format some hundred times. I am using fixed points and therefore fixed_pkg and fixed_float_types packages. What does that error mean??
> it says Isim doesn't support traceable variables Correct, it does not support viewing of variables. Thats a pity. > fixed_pkg:READ(sfixed) Decimal point does not match number format Then have a look, how the function READ is defined in the fixed_pkg. I assume, that the number of leading and trailing digits in the stimuli file does not fit the format you told the function READ... http://www.eda-stds.org/vhdl-200x/vhdl-200x-ft/packages_old/Fixed_ug.pdf
I am couldn't figure out my mistake :( Here I attach one of my files. I used the fixed point in the same way in the other files too.
Hi Miller. I could solve that error after staring at the same code for three hours :P . I was taking the real type values from a txt file which i assigned to sfixed type variable. Reading the package helped me gain some knowledge :) Thanks
