This is going to start out like the other 53 pages of power supply questions "I'm a student working on a capstone project making an SMPS....". I have 12 months before the final design is due.
I'm thinking of purchasing some software to use at home for the designing of the PCB. The cheapest solution I can think of is Eagle for the eventual complexity I'll have (powering a ~150w load).
Now for the software addons. I was wondering how necessary are SI (Signal Integrity) tools for SMPS designs? I haven't decided on the topology yet, but I know the switcher and controls could generate high frequency signals so it seems pertinent. Now the package for Eagle also seems like the cheapest SI tool, FSPICE at $1k. Now I wouldn't' mind avoiding dropping 1k on this software but if it's unavoidable then its understandable, with a certain amount but not all being reimbursable.
Background: Pertinent to SMPS design: Course on Transmission Lines, Course on intro to Power Electronics, standard EE course on Intro to Power Systems, Course on Linear Control Theory and Discrete Time Controls. Otherwise standard courses an EE senior would have.
Is the investment worth it?
Edit: I should mention I only brought up the layout and EMI issues because of this: http://ecee.colorado.edu/~ecen5797/course_material/layout.pdf
