[Place 30-58] IO placement is infeasible. Number of unplaced terminals (431) is greater than number of available sites (400).
The following are banks with available pins:
[Place 30-374] IO placer failed to find a solution
Below is the partial placement that can be analyzed to see if any constraint modifications will make the IO placement problem easier to solve.

[Place 30-99] Placer failed with error: 'IO Clock Placer failed'
Please review all ERROR, CRITICAL WARNING, and WARNING messages during placement to understand the cause for failure.
[Common 17-69] Command failed: Placer could not place all instances
想请教一下，在按照您的博客笔记执行硬件部分时，实现出现了问题。请问该如何改善，我是应该手动布局布线关掉一些无用的IO吗？
