Mapping design into LUTs...
WARNING:MapLib:41 - All members of TNM group "pll_1_" have been optimized out of
   the design.
WARNING:MapLib:50 - The period specification "TS_pll_1_" has been discarded
   because the group "pll_1_" has been optimized away.

Running directed packing...
ERROR:Pack:2908 - The I/O component "record3_hdmi_out_clk_n" has an illegal
   IOSTANDARD value.  The IOB component is configured to use single-ended
   signaling and can not use differential IOSTANDARD value TMDS_33.  Two ways to
   rectify this issue are: 1) Change the IOSTANDARD value to a single-ended
   standard. 2) Correct the I/O connectivity by instantiating a differential I/O
   buffer.
