<h1>Glossary<a class="headerlink" href="#glossary" title="Link to this heading">¶</a></h1>
|
||
<p>Throughout Icarus Verilog descriptions and source code, I use a
|
||
variety of terms and acronyms that might be specific to Icarus
|
||
Verilog, have an Icarus Verilog specific meaning, or just aren’t
|
||
widely known. So here I define these terms.</p>
|
||
<dl class="simple">
|
||
<dt>LRM - Language Reference Manual</dt><dd><p>This is a generic acronym, but in the Verilog world we sometimes
|
||
mean <em>the</em> language reference manual, the IEEE1364 standard.</p>
|
||
</dd>
|
||
<dt>PLI - Programming Language Interface</dt><dd><p>This is a C API into Verilog simulators that is defined by the
|
||
IEEE1364. There are two major interfaces, sometimes called PLI 1
|
||
and PLI 2. PLI 2 is also often called VPI.</p>
|
||
</dd>
|
||
<dt>UDP - User Defined Primitive</dt><dd><p>These are objects that Verilog programmers define with the
|
||
“primitive” keyword. They are truth-table based devices. The
|
||
syntax for defining them is described in the LRM.</p>
|
||
</dd>
|
||
<dt>VPI - Verilog Procedural Interface</dt><dd><p>This is the C API that is defined by the Verilog standard, and
|
||
that Icarus Verilog partially implements. See also PLI.</p>
|
||
</dd>
|
||
<dt>VVM - Verilog Virtual Machine</dt><dd><p>This is the Icarus Verilog runtime that works with the code
|
||
generator that generates C++.</p>
|
||
</dd>
|
||
<dt>VVP - Verilog Virtual Processor</dt><dd><p>This is the Icarus Verilog runtime that reads in custom code in a
|
||
form that I call “VVP Assembly”.</p>
|
||
</dd>
|
||
<dt>LPM - Library of Parameterized Modules</dt><dd><p>LPM (Library of Parameterized Modules) is EIS-IS standard 103-A. It is
|
||
a standard library of abstract devices that are designed to be close
|
||
enough to the target hardware to be easily translated, yet abstract
|
||
enough to support a variety of target technologies without excessive
|
||
constraints. Icarus Verilog uses LPM internally to represent idealized
|
||
hardware, especially when doing target neutral synthesis.</p>
