Do you have any information about the simulation tool you are comparing to? For some reason i couldnt attach files with my message above, and i cannot post them separately either it appears Thanks in advance for your feedback! Message 10 of Please find attached the multisim model. In my search for understanding more I discovered a recent document that had identified dafasheet error in the multisim model related to the counter executing on falling edge of clock, should be rising edge. I am building a simulation of an old 70s design based on s and I have had adtasheet lot of trouble getting a set of counters to operate according to my expectations.
Is the model that is being used in there shareable? 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.
Message 3 of In the schematics the rco is connected to ENT. Question to the forum: Message 8 datasgeet I am new to NI tools and new to the forums.
This is not the case when connecting to ENP. Most Active Software Boards: Unfortunately it did not solve my headache. The case is not solved — and I have now asked the moderator to remove the duplicate.
Can you provide me with the following information to help the troubleshooting? Message 9 of I am asking because I found another post in this board that noted that the issue was resolved.
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.
