How to mark a floating bus net as noConn in Schematic Composer in IC5141

If the bus pin is (say) outbus<5:0> then give the instance name of the noConn NOC<5:0> - i.e. make it an iterated instance with the same width as the bus. That will sort it.

Hi Andrew,

I used NOC<n:0> and it's working. Thank you so much

But I have one another question, as I am designing sar adc and I have two bus pin name dacout<3:0> and bout<3:0> respectively. So noConn is not accepting the same instance name so can you please suggest to me what exactly I can do in this case? I am attaching here snapshot so it will be more clear.

Well, clearly you can't give two instances the same name, so give them different names. For example NOC1<3:0> and NOC2<3:0> or NOCdacout<3:0> and NOCbout<3:0>. There's nothing special about the instance name having "NOC" in it - you just need to make it a vectored name which has the same width as the bus to which it's connecting.

Unless I've misunderstood your problem?

Regards,

Andrew

Sir Andrew! 

I faced a problem to connect the output (q_bar) of flipflop with BUS and the ended point with ''noconn'' form basic library But it give 1 warning on the output of Flipflop by which the circuit doesn't simulate. please guide 

I'd suggest you first read Guidelines for the Custom IC Design Forum as you'd then see that you should have posted in a new thread, specified the software version you were using, and provided enough information for somebody to have a hope of being able to answer (such as what the warning message was, how exactly it failed to simulate, and maybe a picture of what you've done).

Andrew.
