Hi,

While running HSPICE simulations with following options:

Code:
.OPTION AUTOSTOP
.OPTION POST=2
.OPTION MEASFORM=3
.OPTION PROBE
I am getting .mt# files as blank. The output is not 'failed', but the files are completely blank with 0 bytes size.

The weird thing is with same options and measure statements I got proper output for one of simulation run, all others are failing. In each case the .tr# files are properly generated with appropriate resulting waveform.

I checked .lis, .warnlog and other corresponding files but I found no clue why this is happening.

Any help will be appreciated.

Thank you.

Hi,

update:

I ran earlier simulations with
Code:
-dp # -mt # -hpp
switches, when the .mt# files produced were empty.

I ran same simulations with only
Code:
-dp #
option and now my .mt# files are properly written. But this has increased my simulation time by almost 33%!

Same simulations with
Code:
-dp # -mt #
switches gave blank .mt# files. But after checking the .lis file I saw that 'hpp' was used by the simulator by itself.

Also, with multi-processing, multi-threading and parallel precision options I tried changing the .mt# files format to HSPICE default but still files were blank.

Increasing the warnlimit to 100 has not produced any warnings about .mt# files.

I will try something more meanwhile.

Thank you.
