  • update opt_design_pre.tcl as recommended by Xilinx
  • fixes an issue which incorrectly calculated timing paths
    using different point of origin for Source and Destination clock.
    For example a timing path using clk_main_a0 was computed using:
    Source Clock origin = WRAPPER_INST/CL/clk_main_a0
    Destination Clock origin = static_sh/pcie_inst/…*/TXOUTCLK
    This resulted in Hold Time Violations in certain customer designs.
  • per Xilinx, this was happening because of adding SH_CL_BB_routed.dcp
    without closing post synthesis DCP.
  • Update PYTHONPATH in the common env settings to fix vrs bug
