Cadence Users,

to fix the error: "Out of spice memory",

close the Cadence tool you are using (icfb/icms) and edit the ".cdsenv" file in you home directory. 

In the ".cdsenv" file add the following 3 lines:

cdsSpice.init processPriority int 5

cdsSpice.init languageSize int 400

cdsSpice.init spiceSize int 600

Save the file and then relaunch the Cadence tool you want to use.  If the error persists, try raising the last 2 parameters.
