Fixed some constraints. Some paths not constrained; eg no clocks on tmg_io pins, many CDCs go from fast into slow domains need reviewing to ensure pulse widths can be captured and latched.

Timing: added constraints for tmg_clk[1,2] and a script to analyse timing paths, identify some problems and apply a set_max_delay -datapath_only for synchroniser CDCs.

Script to find synchronisers, identify their clocks and periods, then apply an appropriate set_max_delay constraint. Rather than a set_false_path...

Generates a bitstream but no diag unit for t2

Timing is broken. False pathing inputs into CDC synchronisers (posedge searching). This helps timing, it's still broken, so more needs to be done.

Added 200m clock for delayctrl, builds through to route, DRC failures prevent bitstream generation...
