netlist-viewer's Introduction

netlist-viewer

Netlist Viewer is a tool capable of loading SPICE netlists and convert them in a schematic (i.e. graphical) format. The graphical representations helps to understand the electrical/electronic circuit represented by the SPICE netlist, and save some tedious work.

Screenshots

Past versions of Netlist-viewer

Past versions, namely version 0.1 and version 0.2, were hosted in Sourceforge, see https://sourceforge.net/projects/netlistviewer/. All new developments have been moved into this Github project.

How to build from sources

NetListViewer is a pretty simple application with 2 main dependencies: wxWidgets and Boost. Some simple notes on how to build NetListViewer for Windows and for Linux are available.

Status

The software is usable even if it could be improved very much. Since the creation of the project (2010) I have not been using this tool anymore (I'm not doing any HW design anymore) so this software will not be further improved unless someone else wants to step up to improve it. Pull requests are of course welcome anyhow.

netlist-viewer's Issues

Proper unit tests are needed

Inside app.cpp there is some raw unit testing code enbaled by "SELF_TESTS == 1". This should be instead some unig test written using GTest framework possibly.

Can you add an ability to open in the File/Open spice netlist file with any extension?

Hi, Thank you for such a tool. I have a suggestion.
Right now netlist viewer can open files only with certain extension. Unfortunately spice files do not have standard for extension and i have to rename files to open them
Can you add an ability to open in the File/Open spice netlist file with any extension?

thanks
Alexander

Rotating elements in the schematic should be more intuitive

As reported by several users

" It took me a while to figure out (by staring at source code) that you rotate parts by using the right mouse button while dragging with the left. "
" it took me while to understand how to rotate circuit elements. This is done by left-dragging a component and at the same right clicking."

Netlistviewer Error (Kicad)

I am trying to view a Netlist prepared for Kicad and get the following error:

The nelist file 'wd/board.net' didn't contain any subcircuit

After looking at the code and the SPICE format these are quite different [1]. Is there any possibility of extending the capabilities of this tool to include support for Kicad netlists?

The use-case is developing circuits using skidl [2] with no way to visualise the circuits (the export function is quite broken).

Attached should be the example circuit (used for a different issue).

Problem dealing with extra parameters on subcircuits

In my netlist I have the following subcircuit:

.SUBCKT memristor TE BE XSV
.params Ron=893 Roff=1833 D=0.2212 uv=0.0108 p=4.64 xo={xo}

* Biolek Window Function
.func f(V1,I1)={1-pow((V1-stp(-I1)),(2*p))}

* Memristor I-V Relationship
.func IVRel(V1,V2) = V1/(Ron*V2 + Roff*(1-V2))

* Circuit to determine state variable
Gx 0 XSV value={I(Gmem)*Ron*uv*f(V(XSV,0),I(Gmem))/pow(D,2)}
Cx XSV 0 {1}
.ic V(XSV) = xo

* Current source representing memristor
Gmem TE BE value={IVRel(V(TE,BE),V(XSV,0))}

.ENDS memristor

I get an error "Unknown component type for '.params' "
