Worst Paths Information
***********************
Path information for path number 1:
- User constraint on ending point: 0.000
= Required time: 10.000
- Propagation time: 9.116
= Slack (critical) : 0.884
Starting point: XLXI_12.I5.I_Q1.I_36_35 / Q
Ending point: onesout[6:0] / onesout[3]
The start point is clocked by stopwatch|rst_int_inferred_clock [rising] on pin C
The end point is clocked by clk [rising]
