Don Thomas 1998 1 MỄ Simulation of Digital Systems Simulation What do you do to test a software program you write - Give it some inputs and see if it does what you expect - When done testing is there any assurance the program is bug free NO - But to the extent possible you have determined that the program does what you want it to do Simulation tests a model of the system you wish to build - Is the design correct Does it implement the intended function correctly For instance is it a UART Stick in a byte and see if the UART model shifts it out correctly - Also is it the correct design Might there be some other functions the UART could do Don Thomas 1998 2 MỄ Simulation of Digital Systems Simulation checks two properties l functional correctness is the logic correct - correct design and design correct l timing correctness is the logic interconnect timing correct - e.g. are the set-up times met It has all the limitations of software testing Have I tried all the cases Have I exercised every path Every option Don Thomas 1998
