Multi-cycle PATH的基本用法

set_multicycle_path -setup 6 -to C_reg[*]
set_multicycle_path -hold 5 -to C_reg[*]














特殊的design下












因為有不同的path所以要特別的指定路徑
set_multicycle_path –setup 2 –from A_reg/clocked_on \
-through U_Mult/Out –to B_reg/next_state
set_multicycle_path –hold 1 –from A_reg/clocked_on \
-through U_Mult/Out –to B_reg/next_state
