Setting Up a New Cadence Project

Setting Up a New Cadence Project Using OpenAccess and the IBM_PDK

Make a new directory to use

[maryh@node1 ~]$ mkdir project2
[maryh@node1 ~]$ cd project2

Copy the MOSIS files to this directory, making sure get .cdslib and .cdsenv. These files come from the IBM_PDK home, in /IBM_PDK/cmrf8sf/V1.6.0.3DM/cdslib51/examples

[maryh@node1 ~/project2]$ cp -R /net/sw/mosis/IBM_PDK/cmrf8sf/relDM/cdslib/examples/* .
[maryh@node1 ~/project2]$ cp -R /net/sw/mosis/IBM_PDK/cmrf8sf/relDM/cdslib/examples/.cds* .
[maryh@node1 ~/project2]$ ll -a

Our setup has all these files as read-only so no one accidentally overwrites them. This requires running the chmod 644 command to allow the owner to write to these files.

Note that the .cds* files can also be located in the user's home directory. However, those in the project directory take presidence over ones in the home directory.

Start virtuoso Note in earlier versions the command was icfb. Note that if everything is working properly, you will have an IBM_PDK menu choice.
```
[maryh@node1 ~/project2]$ virtuoso &
```
If the menu isn't present, scroll back through the log to find out what went wrong. Even if the menu does appear, still check the log for other errors. The log is your friend.
Next step is to merge the display file. In the CIW (which is the window that opens after starting icfb), choose Tools -> Display Resource Manager
In the next window, choose Merge
Read the info message that pops up which explains what's happening here.
In the window that appears, select all the drf files, starting with cmrf8sf. Name the destination DRF, display.drf and hit ok. Then close the Display Resources Tool Box window.
In the CIW window, choose Tools -> Library Manager
Make yourself a new library to use for your design.File -> New -> Library
Give it a name
Choose Attach to an existing techfile
Choose the cmrf8sf library to attach
Make a new cell view with File -> New -> Cell View
Give the cell a name. Note to change the Open with to Schematics XL from Schematics L. It's not a big deal, but if you don't do this, you'll get a message about not having the Schematics L license when you open the file. (It will then ask to use a higher license and everything will work fine.)
Start drawing the schematic!

When quitting, this error might appear. Just save the file as display.drf again.
