Document Summary

If a user enters a second dime in the dime state, our fsm should reject the coin. We create a rejectd state and add it as the next state from dime when a dime is entered: the rejectd state rejects the dime (a = 0) and continues to wait for a quarter (p = 0). October 16, 2015: what should we use as next states from rejectd? (cid:131) (cid:131) If the user enters a third dime (or a fourth, or a fifth, and so on), we want to reject the new dime as well. + are: here gray boxes are don"t cares and numbers in them are what we would use to get the simplest possible expression for the corresponding boolean functions. Final implementation: to be implemented and simulated in mentor graphics (lab 8, control logic was already done in lab 6, and assembled on the prototyping board in lab 9, control logic was already assembled in lab 7.
