create_generated_clock on multiple signals

Thanks sstrell! a TCL loop was indeed the answer. I did have a hard time with a few of the characters in the create_generated_clock constraint which prevented the loop variable from being inserted properly. I ended up having to create full strings and inserting them as variables in the constraint. Here was my solution for others to view:

for {set x 0} {$x < 60} {incr x} {

set PA_SCLK_source "{u_top_SOPC|the_core_$x|core_$x|clkGen_DDR_out_inst|ALTDDIO_OUT_component|auto_generated|ddio_outa[0]|muxsel}"

set PA_SCL_pins "{PA_SCLK[$x]}"

create_generated_clock -name PA_SCLK_$x -source [get_pins $PA_SCLK_source] [get_ports $PA_SCL_pins]

}

This created 60 instances of the following with reference numbers incrementing (0-59):

create_generated_clock -name PA_SCLK_0 -source [get_pins {u_top_SOPC|the_core_0|core_0|clkGen_DDR_out_inst|ALTDDIO_OUT_component|auto_generated|ddio_outa[0]|muxsel}] [get_ports {PA_SCLK[0]}]
