Serial transceiver txoutclk is not being generated

Hi,

 

I've designed the TX only SDI design for ZCU102 from ZCU106 12G-SDI pass through example design. 

Modified the example design as required for TX only design. 

 

The serial transceiver reference clock is given from the FMC card, which has a 148.5 Mhz  clk oscillator (default clk out).

 

I am not able to get the txoutclk from the GT core.  I've double verified my reference clk and transceiver constraints on the .xdc file.

 

Regards,

Vinay

Re: Serial transceiver txoutclk is not being generated

Hi @vinay_shenoy,

 

How are you checking the TXOUTCLOCK?

Could you make sure the GT is not held in reset?

Did you check the configuration (MGTREFCLK selection?).

Hi,

I suspect a problem with the SDI GT in the design. Adding the GT signals to ILA for debug. Will update you

@vinay_shenoy

 

From the last email from your SR, you were able to get TX and RX RESETDONE. Is txoutclk still not being generated?

Hi @florentw @xud

 

I am away from this debugging for sometime now. Surely I'll update the findings and observations.
