to solve how segv error

[abida.munshi]

While simulating a MOSFET structure, i am getting the error message,
"Process interrupted by signal SEGV". The code written is for obtaining
switching characteristics of mosfet.....

That's a segmentation fault, I believe, implicating the code,
or more likely the memory management scheme invoked
by the compiler. You may have options there that you
can call out, to do better. But look, too, at things like
how the model behaves at "out of bounds" terminal I, V -
blowup or even simply non-convergent numerical behavior
can cause excessive memory and filesystem data volume.

Very small unrealistic capacitances can cause a lack
of transient convergence. If you get to choose between
numerical methods, try an alternate that tends to be more
stable (like Euler in SPICE, better than Gear2 which is way,
way better than TRAP for everything but solution time on
well behaved unchallenging circuits).
