An Intelligent Design Run (IDR) is a special type of implementation run that uses a complex flow to attempt to close timing. Because an IDR can be aggressive, a compile time of up to six times that of a standard run can be expected. Typical compile times, however, are 4.5 times that of a standard run.

The IDR presents a simple user interface around complex timing closure features, and achieves results at least on par with FPGA experts for a high percentage of designs.
