Hi
I am trying to add custom Instruction block to my SOPC Builder Design but i find the printf gets blocked whenever i add custom instruction to my design .I even powered off and powered on by board but still i see that the Printf doesnt print on the console
Go to QuartusII project directory and then, delet db and incremental db directory from that and recompile your Qurtus project. Then try, printf will be there on console of NIOSII IDE.
if i recomplile the quartus project i found that db and incremental db folders are again getting created
so please tell me whether after deleting db and incremental db folders do i need to re-synthesis
quartus project or shall i just run nios -ide compiler
Say you are getting problem in printf now every thing else if working fine in NIOSII IDE (say i = j+k then you may need to resynthesis and compile your quartus project, before recompile and resynthesis you need to delet db and incremental db folder form your quartus project directry and after new compilation and synthesis db and incremental db will agin created you need not to delet at this time untill you want to resynthesis and compile again.

Hi,
As per your mail and error i conceived that u have selected burst mode , in this case u have to mention the min datawidth =1. Actually assertions are inbuilt in IPs. May be they exiting the simulation if condition is voilated i.e. datawidth =0
