FPGA/Design Compiler: Hierarchical constraints with dc2ncf are not supported

Description

Keywords: M1.5, M2.1, dc2ncf, constraints, hierarchical

Urgency: Standard

General Description:
Why does dc2ncf not pass my lower level constraints?

Solution

dc2ncf expects flattened designs. Therefore, unless the design has been flattened, lower level
constraints will be ignored.
