8.2 Abel - Ignoring ABEL reg_t attribute

Description

During implementation the tools are ignoring ABEL reg_t attribute

Solution

This is not a bug in the normal ABEL flow. Istype'reg_t' only declares that the ABEL equations are defining a T-flop expression. In the normal fow, the CPLD fitter always analyzes the D-flop versus T-flop forms and uses the more efficient one, regardless of the design source.
