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):
2. Install libstdc++2.10-glibc2.2 package.
Unfortunately, this package is absent in recent Ubuntu versions, so download it from Ubuntu Dapper repository: https://packages.ubuntu.com/dapper/libstdc++2.10-glibc2.2 and install it:
3. Make some necessary links
4. Install en_US locale (Ubuntu uses UTF8 by default):
5. Probably you will need to make some changes in your xorg configuration:
Add following strings into /etc/X11/xorg.conf
(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:
and restart session (NOTE: it will restart your current session!):
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.
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:
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.
