If clk1 is a source-synchronous output clock and you don't care about the tco in the FPGA for this output port, you don't need an output delay on clk1 itself. To keep it from being listed as unconstrained, you can set_false_path -to [get_ports ...
The copy process is performed on netlist level to pass on the routing information to the false circuit. GliFreD allows an arbitrary LUT configuration; since both control signals CLK and active should be connected to each LUT, the function f each LUT can realize is limited to a 4-to-1 ...

During shift, TEST_EN is asserted in order to allow CLK pass through the clock gater to shift the scan chains. During capture, TEST_EN is deasserted and the clock gater is controlled by its functional enable pin FUNC_EN. To reduce the capture power, the test generator can deassert the ...
