The best advice I can give you is to go back and read the introductory and tutorial material for the software package. We can't be much help if you refuse to spend the time learning the basics. You need to learn how to crawl and walk before trying to run a marathon.i wanted to make a 20Bit sync count Up with parallel load input for the 4 most significant bits in logisim but i have no idea how to start.
Can someone help please ?
Not a lot to go on. Is the problem that you don't know how to make a counter? That you don't know how to make a synchronous counter? That you don't know how to make a parallel load? That you don't know how to make the parallel load only affect the most significant bits? That you don't know how to do something specific in Logisim? That you don't know how to do anything in Logisim?i wanted to make a 20Bit sync count Up with parallel load input for the 4 most significant bits in logisim but i have no idea how to start.
Can someone help please ?
A Sychronous counter1. Sychronous or asychronous counting?
Binarybinary outputs
I am allowed to use everything4. What are the chips do you have / allowed to use?
Thanks a lot i will tryFor CMOS, you may use 4029 or 40193.
For TTL, you may use 74LS191 OR 74LS193.
Of course, there are other chips that I didn't mention. But I think the above chips are the easiest to use.
So first download their datasheets using google and decide which one you'd like to begin your design with. You'd need 5 of the same chips to make a 20 bit counter, once you make up your mind.
