In the following scenario, the launch clock CLK1
is the fast clock and the
capture clock CLK2
is the slow clock. See the following figure.
Figure 1. Multicycles Between FAST-to-SLOW Clocks
In the next example, the launch clock CLK1
is the fast clock. The
capture clock CLK2
is the slow clock. Assume that CLK1
is three (3) times the frequency of CLK2
. See the following figure.
Figure 2. Multicycles Between FAST-to-SLOW Clocks
The setup and hold relationships that are resolved by the STA tool when no multicycle is applied are shown in the following figure:
