I have some problem using quartus ii 11  

 

my code is: 

 

 

 

 

I get the following errors: 

 

 

Error: Port "i1" does not exist in primitive "nand2" of instance "g2" 

Error: Port "i2" does not exist in primitive "nand2" of instance "g2" 

Error: Port "o1" does not exist in primitive "nand2" of instance "g2" 

Error: Can't elaborate top-level user hierarchy

Hi, 

 

I did not see any code of you. I assume you have a name mismatch between the NAND itself and the instanciation of the NAND. 

 

Kind regards
