When defining Pblocks, you might look at utilization from a placement perspective only. However, for static Pblocks with the CONTAIN_ROUTING constraint enabled, routability is also an important factor. Unlike Pblocks without a containment requirement, the router must find a solution using the available routing tiles inside the static Pblock. Therefore, it is important to stay within the recommended utilization value. This approach provides more solution space for the router and allows you to converge to a solution more quickly.
