hey. theres a piece of simulation software thats been commercial but is now free. its called Micro-cap 12. check it out. the list of components is pretty extensive. i used to use the student edition in college and it was great. it was going for over $4800.00 not too long ago but the company folded and let it go now for free. its really good... ill bet that will solve your problem ...
