Differential clock generation using PXI-6570

[Appz$13$]

Hello all, I have been trying to drive a differential clock using the PXI-6570, but I have run into a roadblock. I am trying to drive differential clock via the Digital Pattern editor, where I configured C1 to Return to Low mode and C2 to Return to High mode, while keeping the Drive return, drive off and compare strobe values the same, in the timing file. (C1 & C2 are the pin names). The problem I am facing is that C2 assumes a missing/invalid timing or pin state error in the pattern file.

I am also using 5 parallel data lines along with a master reference clock sourcing in the same pattern file. I am attaching a screenshot of the issue I encountered, after implementing the opcodes of the pattern file. Thanks in advance for suggestions and fixes recommended!!!

please attach the timing sheet and pinmap (to understand if you're using pins or pingroups)

Thanks for your reply! Please find the attached zip file with pinmap and timing files.

It looks like your Timeset names are different for both C1 and C2, please see if fixing that helps.

Thank you for the assistance, Santosh! A really silly mistake was overlooked, which caused the issue. The fix is made, and I see the expected waveforms too.
