*Error_Message:

File too large: "input.raw/tran.tran"

*Problem:

You are using MMSIM 6.1, 6.2, 7.0 or higher and are running a long transient
simulation. In previous versions of spectre, the tran.tran file was broken up
into 2 Gig files. In these MMSIM versions, one large file is created.

You cannot read this large file using IC 5.1.41 awd or wavescan.

*Solution:

In IC 6.1 we have added support for native large files and that also means that
MMSIM can now write them. However, IC 5.1.41 cannot read these files.

The default in MMSIM 6.X and higher is to write the large files. To view the
file, you will need to use the IC 6.1 waveform. tool ViVA.

To use MMSIM 6.X and higher with IC 5.1.41, you MUST set these variables:

For Spectre writing PSF data:

setenv PSF_WRITE_CHUNK_MODE_ON true

For UltraSim writing PSF data:

setenv PSF_LARGE_FILE_ON false

If you do not set these variables, MMSIM may write a file which cannot be read
in IC 5.1.41.
