Arria 10 TSE with GXB

Dear Sir, 


I am working on a design on the DE5A-NET-DDR4. But it is not for 10G or 40G Ethernet. 

It is a Gigabit Ethernet design. It is from our old project. It was working well on the  

Arria 5 starter kit. It uses a TSE with LVDS design for the PCS and PMA. I am not 

modify it onto the DE5 board, by modifying the PMA into GXB. In addition, the GXB needs 

two additional clocks, tx_serial_clk and rx_cdr_refclk. I have used an fPLL to generate 

a mcgb_serial_clk for the tx_serial_clk and a 125Mhz from input pin (it is from a clock  

synthesizer si5340). The compilation is ok now. The PCS configuration is follow the 

TSE manual to set as below. 


0x13 = 0x13 

0x12 = 0x12d0  

0x00 = 0x5140 

0x14 = 0x0000 

0x00 = 0xd140 


The attached jpg file is the verilog code for the tse connection check. I don't know why the 

pcs loopback is not working.
