Pin assignment in Quartus II

Hi all,

After my design is added to the project if I tried to assign the pins automatically using compile Design option or I/O assignment analysis option available under compile design tool is giving a critical warning stating that "No exact pin location assignment for 29 pins of 49 total pins". This is happening for all my designs. Only Data pins are getting allocated every time i tried.

Although i can allocate them manually using pin planner, but I need the default or suggested pin allocations.

Kindly help me

    Thanks for the reply, But how about if the Address pins are not allocated, i.e if it produces the warning message which I mentioned in previous post.

    Hi,

    did you have look into the <>.pin file? It is located in your project directory. Could you find all your pins in the file ?

    Kind regards
