NGDBUILD M1.4: DC2NCF is not invoked automatically for .sedif and .sxnf files


Record #2911

Product Family: Software

Product Line: FPGA Implementation

Product Part: ngdbuild

Product Version: 1.4.

Problem Title:
NGDBUILD M1.4: DC2NCF is not invoked automatically for .sedif and .sxnf files


Problem Description:
Urgency: Standard

General Description:

Synopsys-generated files .sedif and .sxnf may be accompanied by a .dc file
which contains Synopsys constraints. NGDBUILD does not automatically run
this tool.


Solution 1:

Whenever a Synopsys design is synthesized or a new .dc file has been
generated, be sure to run:

    dc2ncf <design>.dc -o <design>.ncd

to make sure your constraints are read into the implementation flow.
