119 formal void parameters added to keep -Wstrict-prototypes happy.
Process found one real missing prototype in vpi/vcd_priv.h:
EXTERN void vcd_names_delete(struct vcd_names_list_s*tab);
8 such warnings left, all in Tony's code
Since parameters are now passed by reference use that information to print
the parameter name in a select vs trying to figure it out by searching the
scope looking for a parameter with the same file, line and value information.
Only print the $signed() may need to be removed messages for a select
expression that will actually be cast to signed.
Use the actual parameter information to warn that -pallowsigned=1 is needed
for a parameter when the LSB > MSB.
If a logical pull device is converted into a CA then it is an assignment
with strength, so just emit the appropriate constant to get the correct
functionality (e.g. 1'b1 for a pull up and 1'b0 for a pull down).
Also add missing file/line information.
If modules instantiations were always handled correctly this would not be
needed, but for now looking for the nexus driver outside the scope is
needed to make some of the tests work.
Since the vlog95 code generator needs the strength information we do
not want to hide it behind a concat-Z optimization. For now we abort
the optimization, but in the future we could add parts of this back
in (e.g. all the drivers have matching strength then replace with a
normal concat and a buf-Z if the strength are not both strong. The
original buf-Z should be removed to reduce the number of LPM devices).
The Verilog-A abs(), min() and max() functions can be converted if the
expressions do not have side effects. Also note the new, null and class
property operators from SystemVerilog are not supported.
We can not convert SystemVerilog strings or dynamic arrays to valid vlog95.
This patch adds an error message that they are not supported. There are still
issues with converting some of the dynamic array constructs (the compiler
crashes), but the message is printed before the crash.
This patch adds support for SystemVerilog packed arrays and adds sorry
messages for generate blocks as well as the new SV final and
fork/join_any/join_none statements.
Rework the nexus emitting code to correctly translate most I/O ports.
Fix a few other expression issues uncovered when port translation was
done correctly. Ignore and warn that the SV ++/-- operators and enum
types are not translatable. More updates of the nexus debug code.
This patch adds the ability to print a constant string in a
structural context. It also fixes the argument order for
structural function calls and makes a few improvements in
nexus identification.
This patch uses the new function (ivl_logic_is_cassign) to determine
if a logical was really the base of a continuous assignment. This
allows creating code that more closely matches the original.
This patch adds support for correctly handling most unconnected ports.
Most important is top level ports that are the root of the conversion.
This patch also adds support for emitting more signed constructs when
they are requested. $signed() and $unsigned() are still not supported
or recognized as an error when not emitting signed constructs.
