Hi there,
I'm looking for a Z80A SPICE model for Electronics Workbench 5.0

anyone have any idea if there is one and where I can get one?

Probably!
There is a word generator which can simulate an expected data
pattern. It is about all you can do with EW5.0 for a complex
component. They aren't adding anymore parts to this old version..

There isn't any, AFAIK.

It's almost impossible to model a microprocessor or microcontroller like a Z80
in SPICE.

now thats a pitty :( i really wanted to build a small computer in EWB.
any sugestions of software that will do this?

Try it in VHDL, it can be done! (Not into EW5.0, but in the
appropriate tool)

It's just a matter of definition, where does combinational / sequential
logic cross over to be a micro. That's not really defined AFAIK except in
the physical size of the package you put it in but either road up your not
looking at a trivial undertaking, more like a lifetimes work. Once you build
a replica of a micro into any software package it is only a series of logic
and clocks so get stuck in. If I am still alive when you have finished I
would enjoy looking at it :)

A VHDL model should take about a month.
Longer if you have to learn the VHDL programming nuances.

You said "almost".

Now we're getting somewhere!
