Finally I've got everything working on Ubuntu 9.10. Hope this howto will be useful.
I'm not going to describe in details how to install Ubuntu, Cadence etc. but additional tweaks in order to get it working.
0. Clean install of Ubuntu 9.10 386 Desktop
1. Install additional packages necessary for Cadence.
Maybe some of these packages are already installed on your system, but
to be sure try to install all of them (of course, all of these could be
installed in one go):
| Code: |
sudo apt-get install libelf1
sudo apt-get install ksh
sudo apt-get install nscd
sudo apt-get install policykit
sudo apt-get install ureadahead
sudo apt-get install csh |
2. Install libstdc++2.10-glibc2.2 package.
Unfortunately, this package is absent in recent Ubuntu versions, so download it from Ubuntu Dapper repository: http://packages./dapper/libstdc++2.10-glibc2.2 and install it:
| Code: |
| sudo dpkg -i libstdc++2.10-glibc2.2_2.95.4-24_i386.deb |
3. Make some necessary links
| Code: |
sudo ln -s /usr/bin/awk /bin/awk
sudo ln -s /usr/bin/firefox /usr/bin/netscape
sudo ln -s /usr/lib/libstdc++-3-libc6.2-2-2.10.0.so /usr/lib/libstdc++-libc6.1-1.so.2 |
4. Install en_US locale (Ubuntu uses UTF8 by default):
| Code: |
| sudo locale-gen en_US |
5. Probably you will need to make some changes in your xorg configuration:
Add following strings into /etc/X11/xorg.conf
| Code: |
Section "Extensions"
Option "Composite" "Disable"
EndSection |
(if you do not have /etc/X11/xorg.conf either it is not necessary for
your graphics card, or just create this file and add above lines to it)
Reconfigure your xserver:
| Code: |
| sudo dpkg-reconfigure -phigh xserver-xorg |
and restart session (NOTE: it will restart your current session!):
| Code: |
| sudo /etc/init.d/gdm restart |
6. Install Cadence IC5141, IC610, Assura, MMSIM61 etc.
7. In order to use cdsdoc you will have to make some changes in Cadence itself:
a) Locate all instances of libgcc_s.so and libgcc_s.so.1 in Cadence
hierarchy (they will be located in PACKAGENAME/tools/lib/ or
PACKAGENAME/linux/tools/lib/ , where PACKAGENAME is mmsim61 or assura or
ic610 or ic5141 whatsoever) and rename all of them to *.old, e.g.
| Code: |
mv mmsim61/tools/lib/libgcc_s.so mmsim61/tools/lib/libgcc_s.so.old
mv mmsim61/tools/lib/libgcc_s.so.1 mmsim61/tools/lib/libgcc_s.so.1.old |
It is very important that you will rename all instances of libgcc_s.so
and libgcc_s.so.1 that are in Cadence hierarchy but leave
/lib/libgcc_s.so.1 intact.
b) Locate all instances of cdsdoc and obServer files (they will reside
in PACKAGENAME/tools/bin/ or PACKAGENAME/tools/bin/ , where PACKAGENAME
is mmsim61 or assura or ic610 or ic5141 whatsoever) and open them in the
text editor (e.g. nano) and make the following changes:
| Code: |
#Standard x86 systems
# LD_ASSUME_KERNEL=2.2.5
LD_ASSUME_KERNEL=2.6.31
export LD_ASSUME_KERNEL |
Instead of 2.2.5 you need to write your own kernel version. Current version of your kernel you could find using
You'll get something like
You need to use first three numbers as shown above.
If there is no such a section in obServer file, just leave it intact.
It is important that you will change cdsdoc (and obServer) that are in
your PATH, but you'd better change all of them just in case.
That's it. At least for me - everything works fine on my Ubuntu 9.10 386
Desktops. If you'll find that I've forgot something, and you are not
able to run Candence on Ubuntu after you make all these changes, let's
try to understand what is going wrong together.
