Viewsynthesis - vhdl error: the name "pfalling"/"prising" is undefined

Description

Viewsynthesis v7.2 doesn't support the old Viewlogic subset VHDL
functions or data types anymore. The following error occurs during compile:

vhdl: Error: the name "pfalling" is undifined.
vhdl: Error: this name has an invalid prefix.

解决方案

If the design uses prising and pfalling, as well as any other
Viewlogic subset VHDL functions or data types, you can compile
the code by turning on the "Compile as VS6.x Flow" which is
found in the Advanced settings in the synthesis settings.
