Title: 64 bit cadence, icfb
Post by wave on Nov 11^th, 2008, 10:56am

Hello - I believe we have a 64b version of Cadence.
How do I verify and launch icfb?

Perhaps:
icfb -64 &

thanks
Wave

I would recommend to set the UNIX environment 'CDS_AUTO_64BIT' variable to
CDS_AUTO_64BIT=EXCLUDE:si.exe
This will tell Cadence DFII to use all existing 64 bit executables
except CDL-in/out.

There is no 'icfb -64'.

The focus on 64 bit support has always been to provide 64 bit executables where there is a capacity need. There is no benefit in running 64 bit apps otherwise (it just increases your memory consumption!)

So support has (so far) been limited to layout, stream in/out, physical verification, and simulation. That means for DFII, the "layout" executable is available in 64 bit mode.

In the upcoming IC614 release, Cadence should be providing 64-bit support across Virtuoso, as this is becoming increasingly necessary.

Regards,

Andrew.
