Re: timing report

One way to reduce arrival time is to reduce the Combinational logic between start point and end point(on the top of the report you cna find). Another way , to introduce pipeline register. With this you are splitting the combinatonal logic so you get +ve slack.

Re: timing report

you can use command "set_critical_range" and "group_path".

Usually, this will lead the tool to optimize the critical path.
