you have to 'promote' the register to be an IO-register. It is not the tri-state function adding the delay but the path from an internal register over the IO-buffer to the pin. You can use the assignment editor to do this: From | To | AssignementName | Value | Enabled <empty> | AD | Fast Output regsiter | On | Yes I had the same issue with Cypress' CY7C69013 FX2 USB controller
