Most customers use Cadence products on networked computers, adding a few steps to the installation and configuration process. The exact procedures depend on your hardware and your operating system, so you may also need to refer to their documentation for specific details.
Sharing Files among Platforms
If you are installing Cadence products for more than one platform, you can save disk space by having the different platforms share as many files as possible. Most Cadence directories are platform specific, but you can share several install_dir directories among platforms:
|
adm |
doc |
lib |
local |
veriloglib |
framework |
share |
Distributing Cadence Products across File Systems
The ideal situation is to have one disk large enough for all of your Cadence products. However, if that is not possible, you can distribute the software in several file systems. Possible relocation alternatives are
- By product: the largest products are Design Framework II and Allegro.
- By platform, such as tools.lnx86
Sample Automounting
To run Cadence software, you can mount directories using either a hard mount or an automount. If you install the Cadence software on multiple file servers, you can configure the automounter on the client to transparently select an accessible file server from which to mount the software.
This section assumes that the automounter is up and running throughout the network, and that the "hosts" option is part of the automounter's configuration.
To configure the automounter (instead of using hard mounts), create an /etc/auto.cds file that lists the mount points on each redundant server. A sample /etc/auto.cds file follows:
share -ro,intr server1:/cds/share \
server2:/cds/share \
server3:/cds/share
tools -ro,intr server1:/cds/tools.lnx86 \
server2:/cds/tools.lnx86 \
server3:/cds/tools.lnx86
This sample file for a fault-tolerant configuration configures the automounter to mount the Cadence software from one of three redundant file servers. A single server configuration does not contain the server2 and server3 lines.
After you create this file, reference it in the appropriate place. For example, if you are using an /etc/auto_master file, add the following line to the file:
/cds /etc/auto.cds
If the file server goes down while the mount is in effect, the file system becomes unavailable. When this happens, users should exit all Cadence applications, wait five minutes, and start the applications again. The automounter will select a file server from which to mount the software.
For more information about automounting, see the documentation for your operating system.
