Editing Model Parameters

The TPS7H5001-SP WCA Model allows for editing internal parameters through the use of the F11 window in SIMPLIS. After opening the schematic file "TPS7H5001_SP_SIMPLIS_Flyback.sxsch" simply pressing F11, or sometimes CTRL + F11 will open up the F11 window.

Editing the tolerances can be done in this window by changing the tol parameter for the specific distribution chosen. WC(tol) is used by default, but there are different distributions that can be chosen.

Distribution Name

Definition

WC(tol)

Worst-Case. Returns either 1.0-tol or 1.0+tol chosen at random.
Unif(tol)Uniform. Returns a random value in the range 1.0 +/- tol with a uniform distribution.
GaussTrunc(tol)Truncated Gaussian. As with Gauss() but values greater than (1 + tol) and less than (1 - tol) are rejected, and the program picks another random number inside the Gaussian distribution.
Gauss(tol)Gaussian. Returns a random number with a mean of 1.0 and a standard deviation of tol/3. Random values have a Gaussian or Normal distribution.
