arria10 fitter conflict for pin assignment

hi, all 

I use arrio 10 with altera mac+phy ip. how ca I fix this conflict ? 

project.qsf: 

 

set_global_assignment -name FAMILY "Arria 10" 

set_global_assignment -name DEVICE 10AX115U3F45E2SG# Bank GXBL1F 

set_location_assignment PIN_AG42 -to tx_serial_data_p[0] 

set_location_assignment PIN_AF44 -to tx_serial_data_p[1]# Bank GXBL1F 

set_location_assignment PIN_AG38 -to rx_serial_data_p[0] 

set_location_assignment PIN_AF40 -to rx_serial_data_p[1] 

 

i get error log: 

Info (11684): Differential I/O pin "tx_serial_data_p[1]" does not have a complementary pin. As a result, the Fitter automatically creates the complementary pin "tx_serial_data_p[1](n)" 

Warning (15714): Some pins have incomplete I/O assignments. Refer to the I/O Assignment Warnings report for details 

Critical Warning (12677): No exact pin location assignment(s) for 103 pins of 108 total pins. For the list of pins please refer to the I/O Assignment Warnings table in the fitter report 

Info (176045): Design uses memory blocks. Violating setup or hold times of memory block address registers for either read or write operations could cause memory contents to be corrupted. Make sure that all memory block address registers meet the setup and hold time requirements. 

Error (14566): The Fitter cannot place 2 periphery component(s) due to conflicts with existing constraints (2 HSSI_PMA_TX_BUF(s)). Fix the errors described in the submessages, and then rerun the Fitter. The Intel FPGA Knowledge Database may also contain articles with information on how to resolve this periphery placement failure. Review the errors and then visit the Knowledge Database at https://www.altera.com/support/support-resources/knowledge-base/search.html and search for this specific error message number.

What version of Quartus are you using?

The Pin Planner indicates a correct pair. but the Fitter does NOT recognize what Pin Planner is set. 

 

Configuration now is a mess when I start deleting XXX(n) nodes that Fitter created, as it will delete both pairs. I am creating the Quartus project from scratch after that, unfortunately. Hoping this will fix.
