Detecting DFII bit mode?

berndf over 15 years ago

Hi,

is there a way to detect the bit mode DFII is running

Sub version: sub-version IC6.1.4.500.1 (32-bit addresses) <- ???

either before invoking virtuoso with a command line option or

with SKILL?

Thanks,

Bernd

Hi Bernd,
I wrote CCSis64bit.il for this purpose, you should be able to get it from the solution 11153048.
It should work okay I believe, let me know if there are any problems with it.
Regards,
Lawrence.

Hi Bernd,

You can also use system.LP64 to tell if it's 64 bit. system.? will tell you the available properties.

system.ILP32 is true for 32 bit machines.

Regards,

Andrew

Hi Lawrence,

Thanks for the prompt reply, but

getVersion(t) does not return a string containing any bit mode

infromation, at least not in my version.

getVersion(t)

=>

"sub-version IC6.1.4.500.1 "

Regards,

Bernd

PS: Is there a way to change to plain text mode for editing in thi forum?

Hi Bernd,
I get the following when I invoke 'virtuoso' in 64-bit mode and then run getVersion(t) in it:

sub-version IC6.1.4-64b.500.4

So, if you do not see the "-64b" part of the string, then the executable is running in 32-bit mode, or at least that's my assumption.
However, I was not aware of the system.LP64 or system.ILP32 properties (these do not appear to be documented?, but cool information Andrew, thanks!) - this appears to be more definitive.
Regards,
Lawrence.

Lawrence,

There's a recent CCR to get these properties documented, so hopefully they will be in the future.
