proteus
I’m new to Proteus and deciding wether to use it for my current project.
There are a few EPROM chips in my design that do not exist in the Proteus library:
Is it possible to add them to the Proteus library with support for simulation?
Or is there maybe a generic ROM component that I can configure to behave like my EPROM (like set no of address lines, data lines and propagation delays)?
I have found one way.
Click the Subcircuit Mode icon here:
Then click on the screen, drag and create a box you want your device to look like. In the list you now have highlighted "DEFAULT". You choose "INPUT", click on your box, where you want ports to be. Than do the same with "OUTPUT". Give name to all ports by double clicking or using context menu and properties. You should get something like this:
Then click on the box and choose "Goto Child Sheet". There you can create the circuit. There you need to use INPUT and OUTPUT from the Terminals Mode (the icon right under the Subcircuit Mode icon in the first picture) and name them exactly the same as ports in the previous file. Be careful. Do not put ports on the wire. You have to connect them by the wire as any other device.
You can continue with building circuit in the parent sheet. I didn't find a way how to get it in to library to use it in other projects, but you can always copy it (Parent and Child sheet. If you copy only the box of circuit, the Child sheet will be empty).
I hope this is clear enough. My English is poor.
From the application menu select Library -> Library manager
In the dialog that opens select the library you want (USERDVC in this case) and click the info button to see the path it resides in.
To backup the library just backup the LibraryName.LIB and LibraryName.IDX files.

Unfortunately no, it is not possible. The only way you will be able to do it, is to ask Proteus to add it to their library via the library and model request forums (only available to view by those signed up to the forums via a valid user license), or to create the part yourself.
This document should be a good starting point. There is a lot to take in to fully create a part you can use in VSM simulation.
There is also a shortcut way. Once you create a new part, you can right click, go to properties and tick the "Attach hierarchy module" box. Once you have done that, you can right click the component again and select "Open child sheet". This will allow you to model the internal circuit of the IC, or you can insert an IC with the same specs and functionality, and use the terminals mode to link the pins to your created model.
The only issue with this though, is you can only use it on that particular design, you will be unable to use it in any new designs.
