最近刚开始学APR
不太懂Innovus这个指令的意思

setOptMode -preserveModuleFunction

Determines whether to preserve logical functions at hierarchical module ports.

When set to false , only the hierarchical module ports that have a timing assertion applied on them will be preserved (not deleted, duplicated, or polarity changed). This is the recommended setting since it allows more freedom for timing optimization while not impacting the netlist functionality or the timing constraints.

When set the true , every port of every hierarchical mode will be preserved (not deleted, duplicated, or polarity changed). This is very constraining.

还有想请问一下 setOptMode 和 place_opt 主要的功能是什么呢
