Use this page to set up the Connection Based Limits in Specctra.
The Connection based limits are absolute controls that apply to each pad to pad connection.
Connection Limit Types
Anti Bias Length is the maximum wrong way distance allowed for routing a pad to pad connection.
Crossing Conflicts is the maximum number of crossing conflicts that are allowed whilst routing a pad to pad connection.
Vias is the maximum number of vias that can be used to route a pad to pad connection.
Corners is the maximum number of corners that can be put in between a pad to pad connection.
Changing Limit Values
To change from the default connection limit value, check the limit type that you want to change. And enter the value for the particular value. The Anti Bias Length is a value using the current user units. The other are integer numbers greater than zero. A value of -1 denotes the default value.
