F1.5 Express/VHDL: multiple architectures for a single entity is not supported

描述

Keywords: VHDL, Express, architecture, entity, configuration, synthesis

Urgency: Standard

General Description
FPGA Express does not support the use of a configuration statement within a
VHDL file to select between multiple architectures for a single entity. Only
one architecture may be linked to a particular entity declaration.

解决方案

If multiple entities exist for a single architecture, Express will synthesize
the last one available, regardless of the configuration statement.
