TLM-1.0 header files
====================

Dir: include/tlm_core/tlm_1/

SubDirs: tlm_analysis/
	 tlm_req_rsp/

Files: README.txt


Comments
========

User code should only #include the tlm or tlm.h header file in the include/
directory and avoid including any of the include files in this directory
directly.  All objects defined in this file hierarchy are in the tlm namespace.

The header files are organizated, by subdirectory, as follows:


tlm_analysis/ 
--------------

This contains the analysis interfaces, ports, and fifos. These files were not
part of the original TLM-1.0 release, but have been grouped with TLM-1.0 in this
release of TLM-2.0

Files:
  tlm_analysis.h        (includes the other header files in this directory )
  tlm_analysis_fifo.h   (defines tlm_analysis_fifo )
  tlm_analysis_if.h     (defines tlm_analysis_if and tlm_delayed_analysis_if )
  tlm_analysis_port.h   (defines tlm_analysis_port )
  tlm_analysis_triple.h (defines tlm_analysis_triple )
  tlm_write_if.h        (defines tlm_write_if and tlm_delayed_write_if )


tlm_req_rsp/
------------

This provides support for TLM modeling based on a request/response pair that 
are passed by value. This is the original TLM 1.0 standard, with the addition 
of an overloading of the blocking transport method with pass-by-reference arguments.

Files:
  tlm_req_rsp.h  (includes the key header files from the other directories)

  tlm_1_interfaces/

					tlm_get_if
