Problem Title:
5200 VL libs : FJKRSE or FJKSRE does not function properly


Problem Description:
When using an FJKRSE or FJKSRE macro in a Viewlogic schematic it is possible
the output of the flip-flop does not function properly in simulation or
implementation.  This appears to be a problem with the macro when the CE pin
is left unconected.


Solution 1:

If using either of these macros in your design and you are not planning
on using the CE feature, connect the CE pin to a VCC primitive from the
xc5200 library.
