Hi, sorry my last post wasn't clear enough. I didn't fix signs (don't know much about java programming), I had to rewrite my vhdl code. My intention was to replace the vhdl entry of the lip6 alliance toolset by something better. I started with Xilinx ISE, compiled the code with signs, optimized with berkeley tools, and then P&R with alliance. Very complicated, but it worked. The hardest part was to write vhdl code that worked with xilinx (for fpga) and also with signs (for asic).

Jepp, the project seems abandoned. At least I don't actively develop or maintain the signs codebase anymore. Guenter, shall we post a note on the signs homepage about the current state of code and support?

Hello, I did some projects with signs 2 years ago. I was also not successful in importing any other lib to signs. Even if you manage to import further libs signs will have syntax errors because many libs contain functions which does not support. I had some more syntax problems, so I nearly had to rewrite the whole code to make it compatible. This project seems to be dead and incomplete.

Hi, I am try to run signs on some projects for opencores.org. Whenever I run anything more complicate the the signs examples I get "Library <which ever library is included> not found" I have tried adding the the files to the lib/ directory in the plugin jar, I have tried adding the files to the sources and recompiling. No luck. If there is anyone still reading this list any thoughts would be helpful. -Nick |

BLIF export is _very_ incomplete as you can see in net/sf/signs/blif/BLIFDump.java. Primitive gates can be dumped and there is some partial support for Mux2 and FD1. Since our development resources (i.e. time) is very limited and BLIF is currently not needed by us, the development of this format has stalled. If you need more features, you are kindly invited to send us patches.

Hi
I've experienced a problem with the blif export of signs 0.63 (on Suse Linux). I tried to synthesize this fifo:
library ieee;
use ieee.std_logic_1164.all;
entity fifo_generic is
generic (
Width : Integer := 4;
Depth : Integer := 4);
port (
Clk : in std_logic;
Clr : in std_logic;
D : in std_logic_vector (Width-1 downto 0);
Q : out std_logic_vector (Width-1 downto 0));
end fifo_generic;
architecture behavioral of fifo_generic is
signal current_d : std_logic_vector ((Depth+1)*(Width)-1 downto 0);
begin -- behavioral
current_d (Width-1 downto 0) <= D;
Q <= current_d ((Depth+1)*(Width)-1 downto Depth*Width);
pipeline_loop : for i in 0 to Depth-1 generate
clock_process : process (Clk, Clr)
begin -- process clock_process
if (Clr = '1') then
current_d ((i+2)*Width-1 downto (i+1)*Width) <= (others => CLK and not CLK); --=0
elsif (Clk'event and Clk = '1') then
current_d ((i+2)*Width-1 downto (i+1)*Width) <= current_d ((i+1)*Width-1 downto i*Width);
end if;
end process clock_process;
end generate pipeline_loop;
end behavioral;
Signs uses a flip flop with set and reset (FD3) when creating the netlist. It seems to be impossible to export this flip flop to blif. From the blif-file I got this error message:
# ERROR: cannot dump /FIFO_GENERIC(BEHAVIORAL)/FD3_7@1c1de1c
Can anyone tell me whats wrong here?
Thanks
Tobias

I am going to assume that this is cannot?? I would like to know if you have tried the tutorial at http://www.iti.uni-stuttgart.de/~bartscgr/signs/wiki/index.php/Tutorial (Note: We are in the process of moving this stuff to SF.) If you are stuck with the tutorial let us know in which step you were stuck. I am not sure if I have understood your description correctly, but I think that after you have done the steps you describe, just try clicking on the bee icon (abeja) and then select your toplevel.

hallo chitta, see http://www.iti.uni-stuttgart.de/~bartscgr/signs/wiki/index.php/Installation#Eclipse_Plugin_Installation dor instructions on how to install the signs eclipse plugin using the update manager (recommended). if you want to install the jar manually, place it in the plugins directory in your eclipse installation and (re-)start eclipse. kind regards, guenter On Mon, 2007-01-29 at 03:34 +0530, Chittaranjan Mandal wrote: > Hi, > > I have downloaded Signs and the command seems to run (trivially > now).

Hallo everyone!
After months of bug-fixing and regression-testing a new signs release is
available:
Signs 0.6.3
http://www.iti.uni-stuttgart.de/~bartscgr/signs/download
While the release focus is clearly on bugfixes, there are some feature
improvements as well such as enhanced test bench support and improved
netlist and simulator views. The VHDL compiler has support for
subprograms now and elaboration of big designs is much faster because of
improved context handling.
Internally the intermediate representation layer was cleaned up, so
intermediate objects form a proper tree now.
Enjoy,
Guenter

Hello, As far as i could read it from your mailinglist there are some problems with the netlist and/or simulation view. Same problem here. I can open the toplevel view and select it, but when i click on "OK" nothing happens. Same in the simulator. I'm running Eclipse 3.2.1 on Mac OS X 10.4.8 with Java 1.5.0. There are no error messages or something else, i've tried it with the example files from the tutorial. I would like to test a unstable build or something from the CVS tree, but i'm not expirienced with building java applications, especially under Eclipse. So maybe there is an unstable plugin anywhere to download and try... Greetings Sebastian |
