XAPP589 v2.4-ERROR: [PICXO-202] /U0/Inst_picxo_top set to GTX but no GT detected


I am using the PICXO versions 2.4 or 2.3 and the tool generates the following Error:

ERROR: [PICXO-202] /U0/Inst_picxo_top set to GTX but no GT detected during opt_design pre_opt.tcl.


This error is generated in two cases:

  1. The GT type has not been set correctly. To resolve this, re-customize the IP with the correct GT type.
  2. If the GT Type is correctly set to GTX and a cell (LUT or FF or others) has been inserted between the DRPDATA_O port of the PICXO and the GTX, this cell might be inserted if a MARK_DEBUG is present on the net.

  • To resolve this, remove the cell present on this connection. The picxo_top_wrapper.vhd can be modified to add the necessary logic for custom design.
  • The next release (v2.5) will allow for 2 cells to be present between DRPDATA_O and the GT.
  • Note that if the GT Type is not GTX, this case does not apply as DRPDATA_O is not used.
