Hi,
I've got Electronics Workbench and Electronics Workbench-Layout.  The latest
version allows you to create a layout and back annotate to the simulator, or
create a circuit in the simulator and have it directly shipped out to the
layout program.  The programs have worked satisfactory but do leave some
things to be desired.  For example: to place a pad in the layout program you
have to actually create a component that is a pad in the component editor.
There is no "stock" pad waiting to be dragged in.  The layout package comes
with plenty of models, unfortunately you are forced to look through all of
them to find what you want (poor documentation).  All in all it has been a
pretty decent low end editor.
BTW:  I'm trying to find a spice model of the Signetics SE5521 chip?

Interesting product only for analog simulation. Have some problems like
other
spice engine with grounding and simulating flotting lines. For professionnal
sound design, it is a problem. If you want to extand, you can get more
models
but It will cost same price as the product. Some specific models like
audiotransformer are not avalaible. Can be use as a front end design package
with simulating, with a low price dos PCB routing product like Layyo. No PIC
models.

Have a nice day,
Dan
