This patch adds support for using a scope in an expression and calling
a user function. It also fixes an issue in the module name mangling
and calling a system task/function with multiple arguments.
This patch adds support for the various case statements and adds
preliminary support for instantiating modules. The module instantiation,
just like the module definition, is still missing ports. Adding this
will require modification to the compiler to get the port order correct.
Because of defparams and passed parameters any module that has a
parameter must be generated uniquely for each instance since they may not
all be the same. Modules without parameters are only generated once.
This patch adds the ability to print a delay expression (it is rescaled
to the module timescale) and adds support the following statement types:
nonblocking assignment with a delay (event control is still missing)
condition (if/else)
forever
repeat
while (Icarus translated for loops to while loops)
fork
procedural continuous assign
deassign
force
release
This patch adds support to the vlog95 convert for the ternary operator,
the concat/repeat operator and calling a system function. It also adds
the `celldefine information when appropriate.
This patch adds more support to the Verilog 1995 converter. There is
still a lot that is missing and there is still some implemented
functionality that is not 100%.
This patch adds support for running cppcheck from the Makefile. It also
standardizes the order of some of the targets. It renames vpip_format.c
to vpip_format.cc and fixes the size of the array tables to make room
for the trailing NULL. Found when using a C++ compiler.
This patch updates all the Makefile.in files and configure.in
as follows:
Do not use the -Wall warning flag when using the SunPro compiler.
The SunPro compiler uses -xMD instead of -MD.
There are still more fixes needed before Icarus will compile
on OpenSolaris.
This is the initial commit in an effort to build a 1364-1995
back end for Icarus Verilog. It is expected that this back end
will allow the user to write 1364-2005 RTL and then using this
back end (converter) generate functionally equivalent 1364-1995
compatible code. This can be used to support older tools in a
work flow. The primary focus will be simulation equivalence,
though I expect to verify logical equivalence as well.
