Installing Cadence

The installation (and use) of the EDA package Cadence seems like folklore, nobody seems to know what they are doing, while some "gods" out there seem to get it right, they are not telling.

Names of packages, and what they do

It seems that even the package names are not well understood.

Cadence Name What I think they are
OpenAccess This is an "open" database that allows interoperability between different vendor's products. It is an industry standard, not a Cadence thing. At the time of this writing (2007), this is a new thing, and not widely implemented. However, should it be widely adopted, it will ease the interoperability of various EDA programs.
IC Analog chip design. Use this for designing transisters on a piece of silicon. Also for RF chips. While this is initiall just for IC chip design, it contains lots of the "foundation parts" of Cadence -- most of the other packages depend on this being installed.
IUS (Old package name was LDV.) Digital design stuff. For VHDL. Also, has some verification tools.

First, what to install first.

It seems that this OpenAccess needs to be installed first. IC seems to depend on it.

  1. OpenAccess
    • Should be called the generic name.
    • Create an instance of it called .../openaccess
  2. IUS
    • don't remember
  3. IC
    • On configuration, you need to deal with IUS

There is some file in /software/Cadence/IC/tools.lnx86/dfII/samples/local called cdsinit. Read it, and follow the instructions. (Make a directory 'local' and copy it there.)
