Calculate a falling-to-rising half-cycle setup path

MediumTiming and STASystemVerilog

A 2.00 ns clock launches data on its falling edge at time 0 and captures on the next rising edge 1.00 ns later. Clock-to-Q is 0.10 ns, maximum combinational delay is 0.65 ns, setup is 0.10 ns, and positive capture skew is 0.05 ns. Ignoring uncertainty, what is the setup slack?

Try it in the question bankReason first. Then compare.
