回复 13#Yekaterinburg
我也是认为set_min_delay似乎可以约束路径
UG里说道:
The following example specifies that all timing paths from ff1/CP to ff2/D that pass
through one or more of {U1/Z U2/Z} and one or more of {U3/Z U4/C} must have delays
greater than 3.0 units.
pt_shell> set_min_delay 3.0 -from ff1/CP -through {U1/Z U2/Z} -through {U3/Z U4/C} -
to ff2/D
