ions of the global environment are brought down to the macro level to guide macro-level implementation. Shadow This is a representation of the global wires overlaying a macro that is used to guide macro physical design and for macro extraction. Timing assertions This is information on the global timing at macro interfaces-arrival times with phase tags on inputs, required arrival times with phas...
