Change path name in qsf to sdc

You can use a Tcl variable:

set fast_clk {pll|altpll_component|pll|clk[1]}

Then use the variable like so:

set_input_delay -clock $fast_clk ...

You might have to work with it a little to get wildcards like the average_calc example.

Also, for exact names, TimeQuest doesn't need the entity name. Notice that the PLL name doesn't do entity_name:instane|entity_name:instance|... for each hierarchy, and instead just does the instance name between pipes. I don't think you can mix this nomenclature with wildcards though, but not certain.
