My Humble House

Ex 1. The path from FF1 to FF2 is designed to take 2 clock cycles rather than 1.

set_multicycle_path -setup 2 \
-from [get_cells FF1] -to [get_cells FF2]
set_multicycle_path -hold 1 \
-from [get_cells FF1] -to [get_cells FF2]

The first set_multicycle_path command specifies that the path takes 2 clock cycles.

The second set_multicycle_path command moves the capture edge of the hold relationship backward by 1 clock cycle.

Ex 2. The path from FF1 to FF2 is designed to take 5 clock cycles rather than one.

set_multicycle_path -setup 5 \
-from [get_cells FF1] -to [get_cells FF2]
set_multicycle_path -hold 4 \
-from [get_cells FF1] -to [get_cells FF2]

The first set_multicycle_path command specifies that the path takes 5 clock cycles.

The second set_multicycle_path command moves the capture edge of the hold relationship backward by 4 clock cycle.
