Path 1: VIOLATED Setup Check with Pin ff8/q_reg/CLK
Endpoint: ff8/q_reg/D (v) checked with leading edge of 'ideal_clock'
Beginpoint: ff3/q_reg/Q (v) triggered by leading edge of 'ideal_clock'
Other End Arrival Time 0.00
- Setup 0.00
+ Phase Shift 10.00
= Required Time 10.00
- Arrival Time 43.50
= Slack Time -33.50
