[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

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

Hi Shakti,

I filed the bug now (# 823228).

I'm using Fedora 16 itself with the latest updates. The version of
alliance that gets installed when I run 'yum install alliance' is
alliance-5.0-32.20090901snap.fc15.x86_64. I tried 'yum install
alliance*fc16*' and that said that no package is available.

Thanks

File a bug at bugzilla.redhat.com against the "alliance" package.
Chitlesh currently maintains the package.

Any reason for using F15? You might atleast want to upgrade to F16, or
you can try to use a F16 VM using virt-manager (for example).

[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

[free-electronic-lab] FEL added to easyfix

Shakthi Kannan — 2012-05-04T16:30:22

Hi,

I have added Fedora Electronic Lab Trac to easyfix:

  http://fedoraproject.org/easyfix/#fedora-electronic-lab

If there is a particular task/ticket that is easy for newbies to get
started with, one needs to add the word "easyfix" in the keyword
section of the ticket, and it will show up at the above URL.

Hola Jose,

I have seen the same error when I was installing Fedora16. Turned out my
DVD disk was bad. I had to re-burn the image on another disk and tried
again and it worked.

Hope this helps.

From where did you download the .iso image from? Did you do a checksum
check on the downloaded .iso image?

How much virtual disk space did you allocate for the installation?

 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-
 friendly meshing tool with parametric input and advanced visualization
 capabilities. Gmsh is built around four modules: geometry, mesh, solver
 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.
