I'm afraid not.
You will probably find that quite a few of the SV design features
are fully supported in that version - interfaces, always_comb,
structs, .* port connection, that sort of thing - but I would
be astonished if you had access to any of the big-ticket
verification stuff such as classes and randomization. To
find out, try these little examples. Be sure to give the
files ".sv" extension, or alternatively use the -sv compile
option to the vlog command.
<example 1>
module enum_test; // probably works OK
typedef enum {first, second, third} ordinal;
ordinal which;
initial begin
which = second;
$display("this should print 'second': %s", which.name());
end
endmodule
<example 2>
module random_test; // I don't expect this to work in MSim AE
integer i, ok;
initial begin
repeat (10) begin
ok = randomize(i) with {i inside {1,2,4,8,16};};
if (ok)
$display("random value is %0d", i);
else
$display("randomization FAILED");
end
end
endmodule
<example 3>
module struct_test; // this probably OK
typedef struct {int a; bit b;} s_ab;
s_ab ab;
initial begin
ab = '{15, 0};
$display("ab.a should be 15: %0d", ab.a);
$display("ab.b should be 0: %0d", ab.b);
end
endmodule
<example 4>
module string_test; // not sure about this one
string s1, s2;
int i;
initial begin
s1 = "hello";
i = 7;
$sformat(s2, "%s, i=%0d", s1, i);
$display("Should print 'hello, i=7': %s", s2);
$display("The word 'hello' has %0d characters", s1.len());
end
endmodule
<example 5>
module class_test; // no chance of this working!
class C;
int a;
string name;
function new(string n = "unnamed", int v=0);
name = n;
a = v;
endfunction
function void print();
$display("%s.a=%0d", name, a);
endfunction
endclass
initial begin
C c1 = new;
C c2 = new("c2", 5);
$display("Next line should say unnamed.a=0");
c1.print();
$display("Next line should say c2.a=5");
c2.print();
end
endmodule
All these examples run just fine in the full version.

All the examples work except for example 2 with Modelsim SE. SE supports all of the "design" features of SystemVerilog as well as SystemVerilog classes. You need Questa for the constraint solver and SystemVerilog Assertions. Which makes sense as that's the harder problem to solve for tool vendors. Now, I'm using SE - which is NOT a "Starter Edition" as the OP indicated. I thought the starter product was "DE" or something like that.

The OEM /Starter Editions are all knobbled a bit, they run at reduced speed or functionality. The base 'normal' spec of Modelsim is PE (Properly Expensive), this is superceded by SE (Specially Expensive).

SVA (and PSL) are supported in Modelsim DE (much cheaper than SE/Questa and it runs under Linux :-), but you are correct regarding the rest.

This version will also work with Spartan 2 but not Spartan 2e. You need at least 5.1 for Spartan 2e, but if you're going to have multiple versions you might as well use version 7.1 I have also heard that version 6.3 is quite stable, although I skipped that version. If you want a version that is sill supported, you might consider 10.1 for the Spartan 2. regards, GaborArticle: 144931

Well, since all I have at home is the Altera free edition and in fact it seems it's the only free Modelsim out for Linux right now (well, Actel has a 45 day trial), I tried these out. Only example complains about missing support: Model Technology ModelSim ALTERA vlog 6.5b Compiler 2009.10 Oct 1 2009 -- Compiling module random_test ** Warning: ex2.sv(5): (vlog-2186) SystemVerilog testbench feature (randomization, coverage or assertion) detected in the design.

Not bad for a freebie... Thanks everyone for your input. My question is relating to the cost of a simulator that supports SystemVerilog Verfication, just how much should I expect to spend for one license? If its too expensive I'll have to stick with sytem testbenches. joeArticle: 144933

Version 6.3 is the last version with EDK support for the Spartan-II. There may not be a (single) version that supports (all of) the Spartan- I and Spartan-II devices. $.02, Gary.Article: 144934
I want to run Quartus on my Debian computer. I see that Altera doesn't officially support Debian. Has anyone here managed to run Quartus on Debian? What was your experience?Article: 144935

What was your experience? My experience with EDA tools on Linux is : use RedHat (or its free sibling Fedora). This is the same syndrom as Windows : all the companies have a "corporate" version of Linux distributed (and sold, and supported) by RH so everybody uses it... I have Debian and Slackware but am quite limited :-( For example, Xilinx does not work well on Slackware. I'm now configuring a brand new netbook with Fedora and I expect many things to work there. good luck and keep us informed, Altera is on my install list ! yg -- http://ygdes.com / http://yasep.orgArticle: 144936

BTW Xilinx tools mostly work on Fedora. The only thing that doesn't work is FPGA Editor which requires MOTIF, Fedora uses LESTIF which doesn't work.

Hello, I want to understand a few things about CPLD programming. There is a configuration sequence followed for FPGA. For e.g. XAPP188 Table 7 on page 11 shows the device configuration sequence to transfer a bit stream. Similarly, is there any sequence for CPLD XC9500? What I understood is that the .jed file is transferred instead of .bit file in the SHIFT-DR state. Is this correct? After transferring the .jed file does XC9500 also need the JSTART instruction and switching to Run-Test-Idle state? Is the entire .jed file transferred or there is some header or similar information which is skipped? Also, how to read the Device IDCODE of the CPLD? How to issue the IDCODE instruction? Thanks for support... --------------------------------------- This message was sent using the comp.arch.fpga web interface on http://www.FPGARelated.comArticle: 144941

A rude hack is installing Openmotif 2.3 and symlinking libXm.so.3 to libXm.so.4... I got it started then, but opening files didn't work. I've also noticed that in ISE 10.1, one of the xilperls is linked against libdb-4.1, which also isn't in Fedora. EDK seems to call that one on occasion. But that's a small library and easily compiled from source.Article: 144942

The .jed describes a bitmap.The jedecfile has to be interpreted first into a
bitmap. The bitmap is then transfered in a complicated way
into the CPLD. The procedures are described somehow in the 1532 Jedec files
and in the files found when searching XILINX.com with "algorithm jedec"
("Device Programming Specification").
xc3sprog on sourceforge implements a reader for jedecfiles and a
XC95X(L|V) programmer with these documents and the sources found in the last
naxjp version with sources (naxjp-079). Read the documents and the sources
http://sourceforge.net/projects/xc3sprog/develop
to understand what's going on.
B.t.w., for the Coolrunner 2 the Jedecfile describes the bits in a logical
order and before transfering in the XC2C CPLD the bits have to be scrambled
in physical order with .map files for the appropriate device found in the
Xilinx ISE/xbr/data folder.

Hi,
I recommend you change your BOOLEANs to STD_LOGIC. Also, assuming this
is targeting real hardware, remember that the insertion of coins is
asynchronous and this is a synchronous design. You'll need some logic
for metastability and to create a one clock-wide pulse to your state
machine.
You can do something like this for a testbench:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
library ieee;
use ieee.std_logic_1164.all;
-- Add your library and packages declaration here ...
entity vending_machine_tb is
end vending_machine_tb;
architecture TB_ARCHITECTURE of vending_machine_tb is
-- Component declaration of the tested unit
component vending_machine
port
(
clk : in std_logic;
rst : in std_logic;
nickel_in : in std_logic;
dime_in : in std_logic;
quarter_in : in std_logic;
candy_out : out std_logic;
nickel_out : out std_logic;
dime_out : out std_logic;
quarter_out : out std_logic
);
end component;
-- Stimulus signals - signals mapped to the input and inout ports of
tested entity
signal clk : std_logic :=3D '0';
signal rst : std_logic :=3D '0';
signal nickel_in : std_logic :=3D '0';
signal dime_in : std_logic :=3D '0';
signal quarter_in : std_logic :=3D '0';
-- Observed signals - signals mapped to the output ports of tested
entity
signal candy_out : std_logic;
signal nickel_out : std_logic;
signal dime_out : std_logic;
signal quarter_out : std_logic;
-- Add your code here ...
begin
-- Unit Under Test port map
UUT : vending_machine
port map
(
clk =3D> clk,
rst =3D> rst,
nickel_in =3D> nickel_in,
dime_in =3D> dime_in,
quarter_in =3D> quarter_in,
candy_out =3D> candy_out,
nickel_out =3D> nickel_out,
dime_out =3D> dime_out,
quarter_out =3D> quarter_out
);
-- Add your stimulus here ...
clk <=3D not clk after 50ns;
Stimulus: process
begin
wait for 200 ns;
rst <=3D'1';
wait for 200 ns;
rst <=3D'0';
wait for 200 ns;
nickel_in <=3D'1';
wait for 1 us;
nickel_in <=3D'0';
wait for 1 us;
dime_in <=3D'1';
wait for 1 us;
dime_in <=3D'0';
wait for 1 us;
quarter_in <=3D'1';
wait for 1 us;
quarter_in <=3D'0';
-- add more...
wait;
end process;
end TB_ARCHITECTURE;
configuration TESTBENCH_FOR_vending_machine of vending_machine_tb is
for TB_ARCHITECTURE
for UUT : vending_machine
use entity work.vending_machine(fsm);
end for;
end for;
end TESTBENCH_FOR_vending_machine;
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
I didn't simulate your design to check its operation. This TB is
simple but it will get you started.

It works on opensuse.

What was your experience? Quartus on Ubuntu is one of requiring themes of Altera forum See here for example for one of the latest threads: http://alteraforums.org/forum/showthread.php?t=5163&highlight=ubuntu There was a wiki entry somewhere. I think they forgot to mention that on x64 before Quartus you have to install 32-bit libraries. Since Ubuntu is based on Debian I'd guess most things said about Ubuntu should be applicable to other Debian variants. More or less ;)Article: 144946
I'm looking for a good stable version of WebPack that supports the old, Spartan and Spartan-2 devices for legacy product maintenance. Any recommendations? Regards; Leland C. Scott KC8LDOArticle: 144947

If you change the booleans to std_logic, you'll need to change all the if statements to have a comparison operator like if (nickel_in) then . . . becomes if (nickel_in =3D '1') then . . . If you're not trying to synthesize this logic, I'm not really clear why you shouldn't use booleans, but then I would normally have used Verilog. On the other hand, if you make the code synthesizable, you can use the Xilinx webpack to generate a testbench template automatically. That often saves the headache of writing the signal declarations, instantiations and initialization logic. Regards, GaborArticle: 144948

More or less ;) I think I'll try it and see what happens. However, I'm not perfectly clear on whether the Linux version is free or not. If it's not, I'm not going to bother going through the pain of installing it, I'll just use the Windows version. So, is it free? I'm talking about the Web Edition.Article: 144949

AFAIK, Web Edition for Linux is still in beta. Still, I see no technical reasons why it wouldn't work for you. https://www.altera.com/support/software/download/altera_design/quartus_we/dnl-quartus_we.jsp
