A Tally Counter

We would like to design a $2-$digit decimal tally counter, which is expected to count the sequence $00-01-02-...-98-99-00-.$ You are provided with a project template in Digital in a file named lab$4$pre.zip. The top design is in testbench.dig. When opened, a module named tally.dig will be seen along two seven segment displays, and a clock input with $100Hz$ frequency. Additionally, two buttons labeled COUNT and RESET are present, which will be used to advance and clear the counter, respectively.

You are expected to place your counter design in tally.dig. Inside this module, you are provided with two instances of decimal counters with LOAD$0$ inputs, which can be used to set the count to $0.$ Other than the count, you are provided with an EQ$9$ output, which, implied by the name, indicates that the count has reached $9$
