Constraint optimization of sub-net level routing in asic design
Functionality can be implemented for optimizing connection constraints in an integrated circuit design. A target timing path associated with a first of a plurality of sub-connections of the integrated circuit is determined. A timing probability value and a route probability value associated with the first of the plurality of sub-connections is determined based, at least in part, on the target timing path associated with the first of the plurality of sub-connections. The timing probability value indicates a probability that timing closure is satisfied on the target timing path. The route probability value indicates a probability that a physical routing track on the target timing path associated with the first of the plurality of sub-connections resolves congestion. A current connection constraint associated with the first of the plurality of sub-connections is modified in accordance with a connection constraint model to which the first of the plurality of sub-connections corresponds.
