Are you using IC5141 with spectre from an MMSIM release? If so, you
probably
need to re-enable the "chunk" mode for writing PSF. In older spectre
versions,
big files used to get split into 2Gbyte chunks, because large file sup****t
was
not particularly common in many OS versions. However, that's no longer
true - so
spectre from MMSIM61 changed to write large transient PSF into a single
big
file. However, sup****t for reading such big files wasn't added into IC61
(I
think), and so if running a new spectre with IC5141, you need to do:
For Spectre writing PSF data:
setenv PSF_WRITE_CHUNK_MODE_ON true
For UltraSim writing PSF data:
setenv PSF_LARGE_FILE_ON false
