Since VHDL variables are scope limited to individual processes (except for shared variables), Modelsim requires that you specifcy the process name while dumping. For e.g.
Code:
p1 : process
variable a_var : bit;
begin
wait;
end process p1;
Hi
İm begineer in FPGA and VHDL. im trying to make a fir filter,,i did almost, i wanted to simulate but there is some mistakes, i want to correct it , but i didnt find where it is. i wanted to see variables in modelsim,,but i couldnt find how. here a friend explained sth but i didnt understand where will i write them etc... is there anyone who knows it a simple way? thanks...
Added after 22 minutes:
ok guys,, i found the way,,for friends who has the same problems..
*give a name to process
*add process tool to toolbar
*right click to name of process in process tool and display option.
*select in region mode, and it will browse click ok. thats all..

Hi,
Once I also faced the same problem.I think you are doing mixed level simulation.The only solution to ur problem is to either change all the variables to std_logic signals or add some extra signal like debug_signals and place them along with the variables which u want to view.So, you can make out what is getting assigned wrong as these debug signal will have the same value as of the variables.
In modelsim, you can add the variable to the wave viewer, to find it, you need to add the windows locals, the variable didn't appears on the Objects windows.
so you need to: View > Locals
You need to select the process to see the variable on the window Locals as display on the following pictures
