I have a test bench in which the input stimulus file length is unknown.
I would like to read the file in to my test bench and loop through each element of the stimulus every clock. The only problem is the the upper limit of the loop is unknown. I created the following to find the file length (number of elements) and use that length as the upper limit of a loop used to read the file into an array which is based off of that length. Here is the code I created (shortened for posting) but
it doesn't work in Model Sim:
. . . signal ind : integer range 1 to 16777216;
--
***************************************************************************= =AD*********-- Determine length of input file
--
***************************************************************************= =AD*********filelength : process
variable index : integer :=3D 0; variable linein : line; variable test : integer; file f2 : text open READ_MODE is "adc.txt";
begin
while not (endfile(f2)) loop readline(f2,linein); read(linein,test); index :=3D index + 1; end loop;
ind
