I need help with the testbench which read from the file.

Test the 18x18 multiplier created by the translators for sign numbers (numbers

expressed in the supplementary code) and verify the created multiplier by:

a) Numbers A = -RRRR and B = DDMM, where YYYY, MM, DD are the year, month and day of your birth.

b) using another 10 suitably selected sufficiently large input values ​​A, B,

each of which has at least one unit and one zero in the four most significant bits

half of the numbers tested are negative. Entry values ​​must be entered as input

the text file and the accuracy of the results must be automatically verified using testbench

file.
