    Posting the complete (expanded) error text would be necessary to understand the conflict nature, you should also tell the FPGA type. Problems of this kinds arise when not executing every step as suggested in the manual, e.g. not importing the tcl scripts with various assignments.

    Hi, thank you for you advice, the problem has been soveled.

    I placed the pin using the following way before:

    assignment- import assignment- import the .avs document

    Then I try to place the pin manually, the error disappeared.

    Thank you all the same, I will give more error information next time~~~
