SMPTE SD/HD/3G-SDI 3.0

[olivierporchy]

Dear all

I am using the SMPTE SD/HD/3G-SDI 3.0 xilinx IP and for a test purpose we need to force the EAV/SAV sequence values to null words ("000 000 000 000" instead of "3ff 000 000 xyz") on the TX output data stream (HD-SDI mode).

My problem is that I did not find how and where the EAV/SAV sequences are generated in the "v_smpte_sdi_v3_0_vl_rfs.v" module.

Is anybody knows this module enough to help me ?

Regards

Olivier

Hi @olivierporchy

I haven't gone through all the RTL, but searching for 0x3ff I found an FSM named flywheel and the description seems to match the functionality you are looking for.

Give this a shot.
