How to get the timing info. for datasheet using PT result

[arthur_wang]

Datasheet requires Min and Max value for parameter 1a and 1b as shown above.
If Dclk is the output clock and Dout is the output port.
I got Worst Case and Best Case STA results.
So there are four timing report which can be used to calc Min and Max value for parameter 1a and 1b
In WC
report_timing -to [get_ports Dout] -to [get_clock Dclk] -delay_type max
report_timing -to [get_ports Dout] -to [get_clock Dclk] -delay_type min
In BC
report_timing -to [get_ports Dout] -to [get_clock Dclk] -delay_type max
report_timing -to [get_ports Dout] -to [get_clock Dclk] -delay_type min

how can i use these timing info to get the Min and Max value for parameter 1a and 1b ?
