![]() Not able to do even a single example can be a reason for rejection. Majority of interviews for freshers would focus on Verilog constructs and coding design examples.Learning Verilog is essential for various reasons.You should also focus on developing testbench environment using Verilog and run the simulation using a simulator.Learning Verilog would require you to implement some design examples starting from basic examples like Flipflop, counters, multiplexers, FIFO, then moving on to designs like Watchdog timer, interrupt controller, Tea vending machine, pattern detector.Majority cases freshers just read Verilog language constructs and assume that they are done with Verilog preparation, actually it is not so.Verilog has been released as part of 2 phases: Verilog-1995, Veriog-2001.You are reading this article, since you understand importance of Verilog coding in VLSI.Use the CLK signal with (1Hz) frequency as your synchronizing clock. Feel free, however to include some kind of indication that there's not enough money in the vending machine to buy a particular burrito. If amount of money inserted is not greater than or equal the price of the selected burrito, no action is required from the vending machine. Assume you will not insert more that $1.00 in coins. A few notes on the implementation: Assume that only one button or switch can and will be pressed at a time. After one clock pulse machine should go back to the initial "00" state and wait for the next customer. Use "BB" for Bean, "CB" for chicken, and "SB" for steak. Use the switches to choose each burrito as follows: SW7 = Bean Burrito SW6 = Chicken Burrito SW5 = Steak Burrito When vending: All the LEDs (LD7 through LD0) should turn on and the seven-segment display should burrito it is vending. BTN3 = $0.05 inserted BTN2 = $0.10 inserted BTN1 = $0.25 inserted BTN0 = reset machine To vend the burrito, the balance displayed should greater than or equal to the price of each burrito (the vending machine doesn't give any change back). Assign the buttons on the DFEB as follows. When initially programed or reset the machine should have a "00" balance. Design the vending machine so that it displays the balance on the two seven-segment displays at all times. The bean burrito should be priced at $0.50, the chicken burrito at $0.90 and the steak burrito at $0.80. It only accepts US coin denominations of 5, 10, and 25 cents.
