在那个大地方本来就不是ideal的吧,我只对clk、rst设置了ideal_network。而Ideal networks are an extension of ideal nets that incorporate automatic propagation of the ideal attribute. the compile command treats all nets, cells, and pins on the transitive fanout of these objects as ideal.所以我对这个命令的理解是只有与clk、rst fanout相关的是ideal的,不过你说的这个倒是提供了一种思路
