1. Replaced shared variables with a normal variable, and global signals with
|
|
a normal signal.
|
|
VHDL-2000 and later requires that shared variables use protected types,
|
|
but protected types weren't available in earlier VHDL versions.
|
|
As a consequence, some simulators in VHDL-200x mode require protected
|
|
types. But some simulators still don't support protected types at all.
|
|
To make pltbutils work in all (or at least in most) VHDL simulators,
|
|
shared variables have now been removed.
|
|
In previous versions of pltbutils, protected types were used by default.
|
|
There were comments in the pltbutils code as an aid to modify the code
|
|
for simulators that don't support protected types, but it was too much
|
|
work to do the modifications. One possible solution could have been to
|
|
make separate variants of pltbutils; one with, and one without protected
|
|
types. But that solution was not tempting.
|
|
2. Removed src/vhdl/pltbutils_type_pkg.vhd .
|
|
3. Added doc/required_updates.txt .
