I tried to simulate the similar 47161 in another simulation tool – and i get the reverse and expeced results; that when RCO is connect to ENT, the carry is forwarded and no “racing” occurs.
Thanks for sharing these files over here! I am especially looking for information concerning the “old 70s design” you want to simulate.
Is the model that is being used dataasheet there shareable? Please find attached the multisim model. Do you have any information about the simulation tool you are comparing to? Message 8 of In the schematics the rco is connected to ENT.

I appreciate any insights. The case is not solved – and I have now asked the moderator to remove the duplicate. Message 10 datzsheet Most Active Software Boards: Message 7 of Message 3 of Question to the forum: They should form a simple 16 bit binary counter that keeps datzsheet until all of the output bits for E4 are all zeros and then it loads all the counters with preset value.
Message 4 of I am building a simulation of an old 70s design based on s and I have had a lot of trouble getting a set of counters to datashee according to my expectations. In my search for understanding more I discovered a recent document that had identified an error in the multisim model related to the counter executing on falling edge of clock, should be rising edge.
Thanks in dagasheet for your feedback! I am asking because I found another post in this board that noted that the issue was resolved.
Message 6 of Message 2 of Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. But, when the second counter’s RCO carries over to the third counters ENT it stays high for a long period of time the duration of the QA and sets off the third counter to “race at clock speed” similar to the first counter.
Message 9 of For eatasheet reason i couldnt attach files with my message above, and i cannot post them separately either it appears When connected to ENT as it appears to be done in the orignal schematics p21, B4 to E4 the third counter starts to race at clock speed when RCO set ENT high as can be seen in the attached simulation screen shot.
Something wrong with the model? Can you provide me with the following information to help the troubleshooting? Message 5 of Message 1 of Unfortunately it did not solve my headache. This is not the case when connecting to Datashee.
I am new to NI tools and new to the forums.
