route_zrt_eco
command performs ECO routing. It first connects the open nets and then fixes the DRC violations. The options control which nets are connected and on which areas of the chip the DRC violations are fixed.
The
route_zrt_detail
command performs detail routing on a design. You run this command after running the route_zrt_track
command. By default, the route_zrt_detail
command analyzes the DRC violations in the entire design and then resolves those violations.
The key difference between the two commands is that you need to use the
route_zrt_eco
command whenever you modify one or more nets. Officially, the route_zrt_eco
command is used to perform incremental routing when you change the design, such as by inserting cells, upsizing cells, or downsizing cells. To fix DRC violations, you should use the route_zrt_detail -incremental
command rather than the route_zrt_eco
command.route_zrt_eco
通常是用在designer修改过电路之后,来perform incremental routing.
route_zrt_detail 通常用来修DRC violations;如 shorts, spacing, width, notch, gap, and end-of-line. 但如果是open net, 则要用
route_zrt_eco
来修
