rtl-opt

Applies local RTL timing optimizations in the user's SystemVerilog style (CSE, hierarchical shared conditions, decode, bit-slice, balanced trees, late mux, equivalent arith rewrite). Use only when the user explicitly asks to optimize RTL, timing, critical path, slack, PPA, or names rtl-opt / /rtl-opt. Do not apply when generating or casually editing DUT. Do not apply to testbench.
