5.1i NGDBuild - NGDBuild hangs during "Checking Expanded Design"

Description

Keywords: NGDBuild, hang, crash, expanded design, error, 2.1i, 3.1i, 4.1i, 5.1i

Urgency: Hot

General Description:
I am using Synplicity 5.1.2, with a top-level EDIF (dakota.edf) with 9 lower-level macros. NGDBuild hangs when it checks the expanded design. (The same behavior occurs on both PC and Solaris machines.)

Why does this error occur?

解决方案

Synplicity 5.1.2 is incorrectly placing an inverter with the signal name the same on both the input and output, which causes DRC to fall into an infinite loop.

The recommendation is to upgrade your version of Synplicity to a newer version.
