Abstract
Connection lines are routed within an integrated circuit. A first set of the connection lines are pre-routed. The first set of connection lines carry signals which have a higher likelihood of being influenced by crosstalk. The first set of connection lines are routed to tracks where minimal capacitive coupling will result. For example, this may be in a track immediately adjacent to a power line or a ground line. Alternatively, or in addition, this may be in a track between two empty tracks. After the first set of connection lines have been routed, a second set of connection lines are routed. The second set of connection lines carry signals which have a lower likelihood of being influenced by crosstalk. The second connection lines are routed to tracks which are not utilized by the first set of connection lines.
