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 . |
