June 1994.

<DL>
<DT><B>vp</B>
    <DD><I>vp</I> is the Verilog parser.  It takes a Verilog
	    file and splits it into two parts.
    <DD> The structural description is extracted and passed
	    to the port allocator.
    <DD> The behavioral description,
	    which contains concurrent, time-driven and event-driven
	    code, is translated into C and output to a compiler.
<DT><B>ap</B>
    <DD><I>ap</I> is the I/O port allocator.  The structural output
	 of <I>vp</I> (<TT>.env</TT> and <TT>.bun</TT> files)
	 specifies which microcontroller
	 to use and the devices that need to be connected to it. 
    <DD> It reads the definition of the devices from the device
	 library and the controller library.
	 (In the diagram they are shown as <TT>.dev</TT> and
	 <TT>.proc</TT> files, but we actually use <TT>.lib</TT> for both).
    <DD> After I/O port allocation, it generates two things:
	<UL>
	<LI> device driver routines in the <TT>.h</TT> file
	<LI> schematic file in the <TT>.sch</TT> file.
	</UL>
    <DD> We have post-processing tools to convert the schematic
       file to other formats.
<DT><B>dd</B>
    <DD><I>dd</I> is the pre-allocation device-driver synthesizer.
    <DD> It is an optional phase, which converts a timing diagram
       file (<TT>.td</TT>, in TimingDesigner format) into a <I>SEQ</I>
       that we normally expect in the device library.
</UL>
