Problem Title:
F1.5, State Editor: Synthesis -> Options to set encoding scheme has no effect
Problem Description:
Urgency: standard
General Description:
When doing an FSM in State Editor for VHDL, there are 2 places where the user may
choose the FSM encoding scheme:
* Synthesis -> Options
or
* FSM -> Machines -> <fsm_name> (Machine Properties dialog box)
Only the latter method has any effect on the synthesized design.
State Editor uses the Synopsys attributes package to explicitly define the
encoding, and therefore the synthesis options' FSM extraction encoding option doesn't have any effec
t.
Solution 1:
When setting the desired encoding scheme for the State Machine, use the
following methodology:
FSM -> Machines -> <machine_name>
Choose the appropriate encoding scheme in the Machine Properties dialog.
