[free-electronic-lab] asimut: Getting a ?u in the output patternwith structural simulation

Ashwith Rego — 2012-05-20T09:29:19

Hi,

I have the following code for an inverter:

============================
--inverter (NOT) gate
entity invg is port
(
  a   : in  bit;
  x   : out bit;
  vdd : in bit;
  vss : in bit
);
end invg;

architecture vbe of invg is begin
  x <= not (a);
end vbe;
============================

I saved this in invg.vbe Next I ran the following commands:
  boom -l 3 -d invg
  boog invg_o invg -x 1 -m 2

This resulted in the file invg.vst which contains the following:

============================
entity invg is
   port (
      a   : in      bit;
      x   : out     bit;
      vdd : in      bit;
      vss : in      bit
 );
end invg;

architecture structural of invg is
Component inv_x2
   port (
      i   : in      bit;
      nq  : out     bit;
      vdd : in      bit;
      vss : in      bit
 );
end component;


begin

x_ins : inv_x2
   port map (
      i   => a,
      nq  => x,
      vdd => vdd,
      vss => vss
   );


end structural;
============================

I now created a pattern to drive the input. However I see a ?u in the
output. I ran the following command
  asimut invg invg invg_out

I do not see this problem when I run behavioral simulations. The
output patterns file is as below. The input file contains ?* instead
of the ?u

============================

[free-electronic-lab] asimut core dumps when there is a save in thepattern file

Ashwith Rego — 2012-05-19T17:41:22

Hi,

I was trying a structural simulation using asimut (I've attached the
files in mux.tar). The files andg.vst, org.vst and invg.vst were
generated by boog.I ran the following command:
    asimut mux mux_in mux_out

The output I got is the following:
###----- processing pattern 0 : 0 ps -----###
###----- processing pattern 1 : 0 ps -----###
###----- processing pattern 2 : 0 ps -----###
###----- processing pattern 3 : 0 ps -----###
###----- processing pattern 4 : 0 ps -----###
###----- processing pattern 5 : 0 ps -----###
###----- processing pattern 6 : 0 ps -----###
###----- processing pattern 7 : 0 ps -----###
###----- processing pattern 8 : 0 ps -----###
###----- processing pattern 9 : 0 ps -----###
###----- processing pattern 10 : 0 ps -----###
###----- processing pattern 11 : 0 ps -----###
###----- processing pattern 12 : 0 ps -----###
###----- processing pattern 13 : 0 ps -----###
###----- processing pattern 14 : 0 ps -----###
###----- processing pattern 15 : 0 ps -----###
Segmentation fault (core dumped)

I'm not sure where would be the right place to report this so I
thought I'd post it here. I also don't know where the core dump is
located or what to do with it.
I have generated a log file using the report feature in Fedora. That
has been attached as asimut_err.

Is there something I missed which caused the program to behave like
this? The issue doesn't come up if I remove the save at the end.

Thanks

[free-electronic-lab] gnucap and ngspice usage and feedback

Yusuf Matcheswala — 2012-05-17T21:42:49

If you have used gnucap and/or ngspice, what has been your experience with
the usage of these tools for simulation especially of larger analog blocks
regarding the tool's speed, accuracy, issues with convergence etc? I will
appreciate the valuable feedback form this forum.

Thanks,

[free-electronic-lab] Xilinx System Generator Alternative

Ashwith Rego — 2012-05-13T13:34:07

Hi,

I have two questions.

1. Are there any alternatives to Xilinx's System generator? Possibly
something that converts octave or scilab (preferably xcos) code to
VHDL or Verilog.
2. What sort of support is available for SystemVerilog in FEL?

Thanks

 Gmsh is a 3D finite element grid generator with a build-in CAD engine and
 post-processor. Its design goal is to provide a fast, light and user-

 and post-processing. The specification of any input to these modules is
 done either interactively using the graphical user interface or in ASCII
 text files using Gmsh's own scripting language.

[free-electronic-lab] [Event Report] GNUnify, February 10-11, 2012,Pune, India

Shakthi Kannan — 2012-02-13T11:30:48

Hi,

I attended GNUnify 2012 [1] on February 10-11, 2012 at Symbiosis
Institute of Computer Studies and Research [2], Pune, India.

Day I

The first day first session that I attended was on "Build your own
cloud computing infrastructure" [3] by Arun Khan [4]. He addressed the
different concepts and tools available for setting up a private
computing infrastructure. After the first session, I moved to listen
to Saleem Ansari's [5] talk on "Torque Box - Ruby App Server" [6].
TorqueBox is small adaptation layer on top of JBoss's Java application
server. I then attended Srikant Patnaik's [7] talk on "Web based
embedded project design" [8]. He demonstrated a simple example of
using an LED with Arduino and controlling it with a Python CGI
webserver. He also demonstrated the use of Fritzing to build the
demoed circuit. All the tools are available on Fedora:

  $ sudo yum install fritzing arduino

After lunch, I attended the talk on "Btrfs - The next Generation
Filesystem on Linux" by Neependra Khare [9]. He addressed the
different problems in the current filesystems, and how Btrfs tries to
solve them. For the last talk of the day I attended Dr. Abhijat
Vichare (from Computational Research Laboratories, Pune [10]) session
on "Portability concepts in GCC". It was a detailed session on the
internals of GCC [11].

Day II

I attended Suchakra Sharma's [12] session on "Developing QT Apps on
Android" [13]. I then went to assist with the system programming
contest organized by Neependra Khare. The participants were given a
written test on the first day, and based on the results few were
selected to compete in the programming contest (sponsored by STEC
[14]). For the contest, few programming problems were given to the
participants to be solved in C within couple of hours time. The first,
second and third prices were worth INR 5000, 3000 and 2000
respectively. Kiran Divekar (Marvell [15]) joined us, and we reviewed
the code and chose the winners. After lunch, we announced the winners
and the organizers and PLUG [16] members helped with the prize
distribution.

I then went to attend Arun Khans' session on "Convert your old laptop
to an useful network device" [17]. He had illustrated with numerous
examples on how he had used old hardware into functional, useful
network devices. It is extremely useful for beginners who are
interested in getting started in working with inexpensive hardware. I
then had a chance to meet and talk with Gen Kanai [18] and Rakesh
"Arky" Ambati [19] from Mozilla. It was also good to catch up with lot
of Wikimedia folks, with whom I went for dinner at the Vaishali
restaurant [20]. Few pictures taken during the event are available in
my /gallery:

[free-electronic-lab] pycells

Yusuf Matcheswala — 2012-02-02T19:00:16

Hi,



Do the layout tools in FEL such as Magic, Electric, Toped etc. use or
provide the facility to create pyCells?



Further, has any one used or knows if pcells can be created using the
pycell studio IDE from Ciranova to create pyCells that can be used in the
above layout tools?



I have seen a utitlity in FEL called skill2py but cannot find any
documentation or data about it?



Thanks

[free-electronic-lab] FEL in Panama

Kiara Navarro — 2012-02-01T06:15:57

Hi everyone:

My name is Kiara Navarro and I'm currently using Fedora Electronic Spin.
Less than a year ago I started in the world of fedora and I could enjoy
this electronic version.
I wanted to write yours because I'll teach a workshop about Fedora
Electronic in Panama and I wish share some material that brings current
Fedora Electronic. This would help me organize the material in a dynamic
way to the public that would be in the workshop.

I searched a lot of information about FEL there is not much in the Spanish
language. However,  initiatives like this in Latin America could help us
better promote spin between the public.

If you have some online conference in which i could see information,
features, activies about FEL would be great, preferably in English.

I'm currently a student of electrical engineering and telecommunications in
the Technological Panama University, and I would like to give more students
the opportunity to know fedora and electronic features offered.

Still, if yours have some kind of idea you'd like to bring to the workshop
is receive.

Thank you very much for the support,

This is my website that it's in spanish www.clase911.com
