There is an option called "Restrict buf/inv bypass to avoid assign statement" on the ' \) h' J+ t. l8 Z1 S* y. w2 T+ E
astMarkHierAsPreserved dialog box .
一開始拿到verilog就要先檢查有沒有assign有的話要請designer把他改掉~之後再開始做~~不然就ECO一次把他改掉# `" h% e. Y' O* I% t
如果一開始沒有的話~~那就Repair Hierarchy~~"Remove feedthrus to avoid assign stmts in hvo" "1"
