These are all very good suggestions, thanks! I had seen the Java circuit
simulator and it is a good example of what I said: it will let you
understand the basics in detail but then you move on to one of the other
tools for larger designs. For a computer architecture course I helped
with in the first half of this year, we used the WinMIPS64 simulator,
which is a modification of the WinDLX tool. There is a Java version of
WinMIPS64, but it is less complete.

One tool that is interesting because it is written in Smalltalk
(VisualWorks) is IDaSS


Some variation of this integrated with Etoys would be very interesting
for me.

What I have been using the most, however, is TkGate. This tool is
written in Tcl and C and the projects can use a mix of schematics and
Verilog. It is very interactive, which makes it good for both
development and education.


One of the examples is an 8 bit processor running the animal guessing
game on a simulated terminal. There is a tool which helps generate
binaries from assembly and microcode assembly source texts.
