Transceiver Standard/Enhanced PCS on Arria 10 GX (Dev. Kit DK-DEV-10AX115S-A)

Hi,  

i have some problems with test about transceiver on Arria10 GX. 

 

My goal is: check transceiver comunication with different speed. 

 

I have already done a test a 5Gbps with Native PHY with indipendent Tx and RX block with Standard PCS (10bit) and Bitslip. The test was successful. 

 

Now i want to test the comunication at 10Gbps using Enhanced PCS (64bit) and Bitslip. The parallel receved are wrong, but the bitslip shift the word by 1 bit every rising edge. The receved word is wrong, because have more '1' than i send by TX. 

 

it seems that an internal coding is applied to the block, but every block aren't enabled. 

 

My option are: 

 

PCS-PMA interface 64 

FPGA fabric interface 64 

 

RX 

FIFO mode phase compensation 

FIFO partially full threshold :23 

FIFO partially empty threshold: 2 

Enable Rx data bitslip 

Eenable rx_bitslip port 

 

TX: 

FIFO mode phase compensation 

FIFO partially full threshold:11 

FIFO partially empty threshold:2 

 

Any advice? 

 

Thanks,  

Marco
