In the schematics the rco is connected to ENT. Message 5 of For some reason i couldnt attach files with my message above, and i cannot post them separately either it appears Dafasheet you have any information about the simulation tool you are comparing to? Message 2 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 operate according to my expectations.

When connected to ENT as it appears to be done in the orignal datashfet p21, B4 to E4 the third counter starts datxsheet race at clock speed when RCO set ENT high as can be seen in the attached simulation screen shot.

Please find attached the multisim model. Unfortunately it did not solve my headache. Most Active Software Boards: Something wrong with the model?

I am asking because I found another post in this board that noted that the issue was resolved. This is not the case datzsheet connecting to ENP.

In my search for understanding more I discovered a recent document that had identified an error in the multisim model related to the counter daatasheet on falling edge of clock, should be rising edge. Thanks for sharing these files over here! The case is not solved – and I have now asked the moderator to remove the duplicate.

Datashset helps you quickly narrow down your search results by suggesting possible matches as you type. I am new to NI tools and new to the forums.

Message 8 of Message 6 of Is the model that is being used in there shareable? Can you provide me with the following information to help the troubleshooting?

Message 10 of Message 9 of Question to the forum: Thanks in advance for your feedback! I am especially looking for information concerning the “old 70s design” you want to simulate. I tried to simulate the similar cascade 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. Message 1 of Message 4 of They should form a simple 16 bit binary counter that keeps incrementing until all of the output bits for E4 are all zeros and then it loads all the counters with preset value.

I appreciate any insights. Message 3 of Message 7 of 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.
