2.2 Place and Route

The Place and Route process requires the I/O, timing, and floor planner constraints. The demo design includes following constraint files in the Constraint Manager window:

  • The io_constraints.pdc file for the I/O assignments
  • The timing_user_constraints.sdc file for timing constraints

To Place and Route, on the Design Flow window, double click Place and Route.

When place and route is successful, a green tick mark appears next to Place and Route.

Important: The file top_place_and_route_constraint_coverage.xml is recommended to be viewed for place and route constraint coverage.
