VHDL Compiler

[Andrew Ganger]

Hi

I would like to play a little bit around with VHDL at home. At
university we use modelsim to compile and simulate VHDL designs.
Is there also a free compiler and simulator out there that could
be used for private purposes?

many thanks for suggestions,
Andrew

Modelsim, from most of the PLD/FPGA suppliers with the web version of their
tools.

GHDL (open source)

Have a look at the student edition of Modelsim:

You can download Active-HDL, like I remember it free for simulation
something like for 1 year.

It's great that they provide it to students at no charge! A bit
disappointing that the student edition is only available for Windows,
as I use Linux for all my school work. Oh well. I shouldn't look a
gift horse in the mouth.

I fully agree and I hope that all students who download a copy gently
suggest to Mentor to not only get Linux support but also dual language and
SystemC. However, I wouldn't get my hopes up to high...........

Thanks Hans, thats great. I tried it, followed the instructions but when
I wanna simulate a design i get the following error message

# vsim work.counter
# ** FATAL ERROR: ModelSim PE Student Edition licensing failure due to
one or more problems with the license key such as:
# - it is not found
# - it has expired
# - it is not for this user
# - it is not for this computer
# - it is not for this version of ModelSim PE Student Edition.

Anyone encountered the same problem? The license file is in the top
level directory as stated in the email with instructions.

Thanks for any assistance

Hi Andrew,

I would also post this on the student_edition newsgroup:

http://groups.google.com/group/modelsim-pe-student-edition

I am not sure what kind of license you have but I suspect it is a simple
node-locked MAC based one? If that is the case make sure you set the
LM_LICENSE_FILE variable pointing to your license file, for example:

LM_LICENSE_FILE=c:\flexlm\license.dat

Alternative, you can run "lmutil lmdiag" in a DOS box to see if you get any
errors on your license file.

Good luck,

Hans.

Which OS?

There are threads on the Xilinx forums discussing incompatibilities between
Modelsim licensing and a relatively recent OS, and a possible solution. (Can't
remember the details offhand)
