Slack and maximum frequency

Slack and maximum frequency. Data leaves the launch flip-flop after clock-to-Q, runs through the logic, and must arrive before the capture edge with setup margin. Setup slack = (period - setup) - arrival.

• Drag the clock period down. As it shrinks, the capture edge moves left and slack falls toward zero. Find the smallest period that still has slack >= 0 - the reciprocal of that period is the path's maximum frequency.

Push to the limit (slack just above zero), then Submit design.
