Hi,
I don't know what the best strategy should be, should the parser be part
of Kicad, or ngspice or a project of its own ? I'd like to implement it
in Kicad as I am familiar with (parts of) the codebase, and it will
allow other IBIS actions than spice ( or just an ibis viewer, I actually
Hi Fabien,
If you are interested, we should move on with this projet.
I would care for the ngspice issues, you might care for the IBIS specs
and the parser.
Are there 'standard' circuits for driver and receiver?
These should be defined as ngspice subcircuits with adequate parameters.
The
To be honest, you are too fast (for me)!
May I ask you to correct me or enhance my following summary:
Goal is a sort of system simulation, where the system consists of a chip
driving a PCB channel, which connects to a receiver chip.
To simulate this, I need a simulator with models for the
Hi,
That's an impressive collection of tools you have on video!
I am personally really interesting in Kicad having a full simulation
toolkit, but that's a lot of work :)
With Thomas, we have been trying to add some signal / power integrity
tools into kicad for some months now. ( mainly on
Hi,
The parser is not finished, not at all. It simply reads an ibis file and
stores data in various C++ classes.
But said classes are designed for the parser to remember an entire file.
Then, I am thinking about adding another layer of classes, that could
interface easily with a simulator (
Also of note...
I've got a bunch of tools in glscopeclient and
libscopehal/libscopeprotocols for NRZ/PAM4 signal generation, channel
emulation, de-embedding, equalization, clock recovery, eye patterns,
etc. Might be worth pursuing some kind of integration to develop a full
channel
I started down the path of creating an IBIS-to-Spice converter a couple
of years ago. I researched it enough to decide it was feasible, then
discovered a commercial product demo that would do enough of what I
needed at the time and stopped working on it.
I'd just about forgotten about it
Hello everyone,
I am working on an IBIS parser for kicad integration.
IBIS is a standard format to I/O buffers, that allows for "fast" and
accurate signal integrity simulations.
While parsing the IBIS format is not so hard, well... I have data to
simulate, but no simulator...
I was wondering
What is your IBIS parser supposed to do?

Fabian,
we may check if IBIS simulation can be integrated into ngspice.
