This should not change the functionality, but to save space trim any
unneeded bits from a binary constant. Also for the case of emitting
a signed undefined value when the allow signed flag is not set add
the width to the constant.
The only known problems left are in files imported from gtkwave,
if not for them you could turn on -Wsign-compare.
Assumes c99 for c code, so the scope of for-loop indexes can be made sane.
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 adds code to make sure a double (Verilog real) constant
is printed correctly. It also adds code to trim any leading escaped
NULLs from an expression string.
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.
This patch adds support for emitting escaped identifiers and adds
code to correctly emit most module port expressions/definitions.
There are some minor code optimizations/cleanup included as well.
This patch add the following functionality to the vlog95 generator.
Add support for most CAs. Selects still don't work correctly.
Emitting a named event as an expression.
Enhance the ability to find a signal in a nexus.
Add code to emit a nexus driven by a constant.
Rework the delay/strength code for logic gates/CAs
Refactor some of the number code.
Refactor the variable emitting code to support named blocks.
Translate the compiler code back to <var> = <event> <value>
