What is VBS?
|
|
</H4>
|
|
This is the public release of the Verilog Behavioral Simulator.
|
|
Verilog is a Hardware Description Language used mostly for digital circuit
|
|
design and simulation. This program is a simple implementation of a
|
|
Verilog simulator. VBS tries to implement all of the Verilog behavioral
|
|
constructs that are synthesizable, but still allow complex test vectors
|
|
for simulation.

What's New in 1.4.0
|
|
<p>
|
|
This release contains many bug fixes and a few new features. The new
|
|
features include:
|
|
<p>
|
|
|
|
Shell interface for Guile<br>
|
|
$dump* API support<br>
|
|
Multiple/lvalue concatenation<br>
|
|
Net declaration assignment<br>
|
|
Delay or event control in non-blocking assignment<br>
|
|
Hierarchical variable reference<br>
|
|
<p>
|
|
There are too many bug fixes to list here. VBS now passes many of the
|
|
test cases in the IVL test suite maintained by Steven Wilson. The
|
|
Makefile includes a target to run through those test cases. The test
|
|
suite can be downloaded from the Icarus project; icarus.com.

What does it look like?
|

</H4>
|
|
There are no screenshots at this point. VBS is a text/command
|
|
line program.
