INSTALL.mkd

+Installation
+============
+
+* This version of systemc-clang compiles as a dynamic library.  It requires LLVM and clang to be installed.   Please follow the directions below
+
+
+Steps
+===========
+* Follow the instructions to install clang: [Get Started](http://clang.llvm.org/get_started.html). Notice that you should also install LLVM as it is needed for compilation of the stand-along program. A suggestion is to install LLVM/clang in a location that is accessible by the user.
+
+* Clone systemc-clang repository.
+
+```bash  
+$ git clone git@github.com:anikau31/systemc-clang.git
+```
+
+* Create a build directory for this stand-alone program.
+
+```bash
+$ mkdir systemc-clang-build
+```
+
+* Enter the cloned repository folder.
+
+```bash
+$ cd systemc-clang
+```
+
+* Edit the path for the LLVM_BUILD_DIR in paths.sh, and set it to the appropriate path where LLVM/clang was installed.
+
+* Source the paths file (assuming bash shell).  This should setup certain environment variables that cmake will use.
+
+```bash
+$ source paths.sh
+```
+
+* Go to the build directory.
+
+```bash
+$ cd ../systemc-clang-build
+```
+
+* Create the makefiles using cmake.
+
+```bash
+$ cmake ../systemc-clang
+```
+
+* If there are no errors, then the compilation of Makefiles was successful.  So, you can go ahead and compile the stand-alone program.
+
+```bash
+$ make
+```
+
+Testing on a small example
+==========================
+
+* Copy the compiled binary in the bin folder of LLVM_BUILD_DIR
+
+```bash
+$ cp systemc-clang $LLVM_BUILD_DIR/bin
+```
+
+* Set the SYSTEMC variable.
+
+```bash
+$ export SYSTEMC=<path-to-systemc-install>
+```
+
+* Execute it on a simple example.  You should see some (debug) information print out on the screen.  Hope to make this more meaningful in the future.
+
+```bash 
+$ $LLVM_BUILD_DIR/bin/systemc-clang ../systemc-clang/tests/module1.hpp -- \
+-D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS  -I/usr/include  \
+-I$SYSTEMC/include  -x c++ -w -c
+```

NOTES.mkd

+Some useful commands and notes
+==================
+
+To speed up the parsing, we use pre-compiled headers. 
+
+* Create the PCH for systemc.h, 
+
+```bash
+$ clang -cc1 $SYSTEMC/include/systemc.h -emit-pch -o systemc.h.pch -x c++ -I$SYSTEMC/include
+```
+
+* Dump the CFG using the following command.
+
+```bash
+clang++ -cc1  -analyze -analyzer-checker=debug.DumpCFG -x c++ <filename>.cpp
+```
+* Dump the Graphviz CFG using the following command.
+
+```bash
+clang++ -cc1  -analyze -analyzer-checker=debug.ViewCFG -x c++ <filename>.cpp
+```
+
+
+* Compile project for Xcode (Mac specific) using cmake
+
+```bash
+$ mkdir build
+$ cmake -G "Xcode" <path-to-systemc-clang>/ 
+```
+

+[systemc-clang](http://github.com/anikau31/systemc-clang): SystemC Parser using the Clang Front-end
+================================================================================================
+
+[systemc-clang](https://github.com/anikau31/systemc-clang) is a revamp of an earlier [SystemC](http://systemc.org) Parser called [SystemCXML](http://systemcxml.sourceforge.net/).  The purpose of this project is to provide researchers and individuals with a parser for SystemC. This SystemC parser uses the [clang](http://clang.llvm.org) front-end. 
+
+The public release will only allow parsing and representation of structural information of SystemC models at the RTL.  This implementation will provide a reflection data structure that a designer can use to extract this information. 
+
+Internally, we are developing methods to represent behavioural information of the SystemC models.  In addition, we plan to support TLM 2.0 models as well.  Stay tuned for more updates and releases. 
+
+As always, please feel free to provide issues, and feature requests.
+

TODO.mkd

+Urgent
+=======
+- There is duplication between SignalInstanceContainer class and a Signal, and SignalContainer. This needs to be fixed to avoid further confusions.
+
+
+In Progress
+============
+- Find connection netlist (bindings)
+- Provide data structure for querying structural information
+
+Fixed
+======
+- Find instances of sc_modules.
+- Find sc_main function
+
+Older
+============
+*Supported but refinements necessary*
+
+FindPorts.h
+-----------
+- DONE: Default types are not handled, but template types are !! huh!
+
+FindEntryFunctions.h
+--------------------
+- Multiple entry functions in different constructors of the same class.
+
+FindSensitivity.h
+--------------------
+- We only handle "sensitive << a << b" type calls. 
+- Have to support .pos(), .neg(), and sensitive_neg/sensitive_pos.
