Hello, I'm having a hard time designing the CMOS transistor level of implementation.

Digital Design Project A Newspaper Vending Machine (NVM) is described as follows: Two coin-slots are available for introducing 5 Dhs and 10 Dhs coins. Two buttons allow selecting whenever a national newspaper which costs Dhs or a magazine that costs 10 DHs each. Note ate that a choice may be the sum of two selections. The customer selects his choice and introduces the coins. Only one coin can be introduced by slot for a desired number of newspapers If the customer makes a selection and the amount deposited is equal to or greater than the price of the selection, the newspapers are delivered, and the excess money, if any, is returned the change calculation is not considered within this problem). If the money dropped in is less than the selection price, the newspapers are not delivered and the money is returned. The newspapers are stored in two different drawers: One for the regular national newspaper and another for the magazine We are asked to design the digital controller of this NVM. (No specification, TT, K-maps, Algebraic expressions, Gate level implementation, NOR level design, CMOS Transistor level Implementation) Digital Design Project A Newspaper Vending Machine (NVM) is described as follows: Two coin-slots are available for introducing 5 Dhs and 10 Dhs coins.
